getting crypto

The two default way to get cryptocurrency is to mine and to buy from miners. After reading the three chapters, you should be familiar in buying cryptocurrency coins. However, you may chose not to buy for various of reasons such as afraid of the loss, still not comfortable with cryptocurrency, or you just do not have a penny to spare. This chapter presents other methods of getting cryptocurrency mostly free but also mostly not much amount.

Using Crypto Powered Products

The best way for starters to get cryptocurrency coins is to try using crypto powered products. It is a good introduction for starters to see what innovations are being developed in the crypto world. While current services such as Google and Facebook keeps profit for themselves, most crypto powered products shares their profit with the users where most of their concept are products are useless without you customers. Even if they do not have profit yet, they can share to you the coins first and add value to them later.

Crypto Powered Browsers

I will take a guess that most of you who are here are Internet literate where you use browsers most of the time. Time to change your browser. Use a cryto powered browser. Disclaimer, most of them are not necessarily decentralized but they give you crypto tokens for using them and they provide extra functions related to cryptocurrency.

Brave Browser

brave rewards tips

The most popular one today is Brave browser, available on most operating systems which are Windows, Linux, MacOS, Android, and IOS. Brave browser changes how online advertisements are presented. From their study that many unwanted advertisements and trackers annoys online user's experience. Not only they contribute to heavy data usage but also getting your personal information for free and without your consent and even worse some of them are malicious. Download and install through this link:

brave shield tor

Brave browser returns the power to you, where you decide whether you want to see advertisements or not and if you choose to see an advertisement verified by Brave you will be rewarded with Basic Attention Token (BAT). From user's perspective a random notification will pop up informing you that there is an advertisement. You can choose to click and see for the reward or ignore. The BAT reward either can be kept for yourself or be tipped to the owner of the website.

Netbox Browser

Netbox Reward Distribution

Netbox browser is said to be decentralized browser where you are rewarded with Netbox (NBX) for using it. The browser have basic Netbox wallet functionality such as send, receive, and backup keys. The most interesting function for me now is the staking function where you can lock your earned NBX to receive more NBX rewards. Unfortunately, it is only available on Windows operating system. Download Netbox browser through this link:

My Netbox Activity and Staking Rewards Transaction

Bittube Extension or Browser

Netbox BitTube

Bittube is my favorite because you do not need to use the browser but you can install the extension on your existing browsers. For example, in Windows, I use Netbox browser with Bittube extension earning NBX and TUBE reward at the same time, and in Linux, I use Brave Browser with Bittube extension earning BAT and TUBE reward at the same time. They called the service airtime which rewards you in Bittube coin (TUBE) for the time you spend browsing while using Bittube extension. Download Bittube through this link:

bittube adblock vpn monetize tips

Other than the similar adblocker function in Brave browser, Bittube provides a very interesting feature for me which is monetization where if anyone especially with Bittube extension installed visits my website, blogs, social media, and other platform, I will be rewarded with TUBE. Other than that, it is originally a video platform like Youtube which is good for me as a content creator. Therefore, I invested in TUBE by staking up to the highest level to get maximum reward.

Cryptotab Browser

Cryptotab CPU Mining

This browser is a fork of Chrome with CPU Bitcoin mining installed. All you have to do is download, install, and press the mining button to start mining. This simplicity is good for starters who either do not want to buy Bitcoin or want to try mining experience but do not want to go through the technicallity. Though it can take days to earn even a Dollar worth of Bitcoin but in roughly two days you will earn enough pennies to withdraw to your wallet. Disclaimer, it technically does not mine Bitcoin but altcoins which will be converted to Bitcoin. Download using this link which are available on Windows, MacOS, Android, and IOS.

Crypto Powered Search Engine



Presearch is an open and decentralized search engine that rewards you with Presearch Tokens (PRE) for your usage, contribution, and promotion. Presearch is on the way to release future versions of the open source platform that will utilize a blockchain-based index curated by the community. These are descriptions from their website and register first using this link before you can earn.

Crypto Powered Social Media Platform



Torum is a social media platform that rewards users' engagement in Xtorum (XTM). The interface design is similar to Facebook giving familiarity to new users. Currently it is still in beta phase and will move to decentralization in the future. Therefore at the time of writing of this chapter, you can only join through invitation link As for me, I am waiting for their smartphone application to come out and at least a mobile friendly website. Different from most crypto powered social media platform, the token reward is gamified by giving you daily, weekly, and monthly missions such as login, make, and share a post everyday, comment on three posts, and like five posts for rewards. Torum will be more than just crypto powered social media. In summary, it will be an exchange integrated with a social media and other products providing utility of XTM token. If you are interested for more information, join now and take a look yourself.



Minds is a free and open source distributed social networking service that uses the blockchain to reward the community with tokens. Minds has become popular for its commitment to privacy, decentralization, optional anonymity, radical transparency, free speech, and user rewards in contrast to the surveillance, secrecy, censorship, and algorithm manipulation it alleges, occurs on many proprietary social networks. Smartphone application is also available and the interface design is as familiar as popular social networking platforms. Join using this link



An emerging social media platform that rewards you in Uhive tokens. The concept is having many spaces and you choose what space to follow (kinda like myspace?). They also have a smartphone application that is well designed. Join at and Use my referral code (GY3WKO) to earn an extra 25% tokens on all your new purchases.



Unlike other platforms, Voice is bot-free and only allows one account per person. This means interraction between real people and no shadiness. You can get rewarded in Voice token for creating popular contents. Currently, it is still in invitational phase and I am still on the waiting list.

Crypto Powered Blogging Platform

Steemit & Hive Blog & Blurt


Steem is its own blockchain initially for contents where they are decentralized. You get rewarded in Steem in Steemit if you make a comment on a post and other people upvoted your comment. It is also said that you get a portion of the reward if you upvote and then other people upvotes after you but I am not so sure. Yes, there was an internal conflict in Steemit where Justin Sun bought it and ended up splitting between Steem and Hive blockchain where Hive is a hardfork of Steem. However as a starting user or content creator, why do you care? Just join both Steemit and Hive Blog and see how it goes. Also Steem and Hive are the blockchain. There are other platforms out there other than Steemit and Hive Blog which I have not explored. Recently, another fork came out called Blurt World where the difference is there is no downvote. Unlike Steem and Hive where those who hold the most coins have the ability to destroy posts that they do not like, Blurt cannot be controlled by whales. Join now at,, and




I first saw Uptrennd as a social media that rewards users in 1UP token for their engagements such as reading posts and commenting but then I saw it to be too much to be just a social media platform because of the length of the posts. Usually a social media platform have people posting few sentences of status but most of the post I see are more like blog posts which is longer than status. Also, be careful when commenting here. At first I did not know that users get 1UP token just for commenting so many people spam just to get the reward. The community hates comments that are not informative even comments such as "keep up the good work", "what a nice post", and "you did well" are regarded as spams. You have to give more informative comments such as asking related questions and giving feedbacks. Join now at



Publish0x is a crypto agnostic platform that rewards you in various of tokens for reading a post. The system is a tipping system but they provide the tips for you. Also, you choose how much to split between you and the author of the post. Naturally, it attracts fantastic posts where this is one of the platform where I found hidden crypto gems also a good place to keep up with cryptocurrency news while getting rewarded. Join now at

Crypto Powered Multimedia Platform


LBRY is a video platform dedicated for censorship resistance and content ownership. As a viewer, you get rewarded by watching videos and following content creators in LBRY credit. They are very fierce in inviting users who hates Youtube's censorship. If you have a Youtube channel, you can back it up to LBRY in just few steps and it will remain synchronized where you do not need to upload to LBRY, just upload to Youtube and LBRY will duplicate the video to your LBRY channel for you. Now they have Odysee which is just the same as LBRY but better design. Join now at$/invite/@0fajarpurnama0:e


bittube tv

Bittube is similar to LBRY but they do not solely focus on multimedia. They have airtime, browser, adblock, virtual private network (VPN) service, content monetization, and TUBE payment. It is more likely that they will expand their services in the future. For now there is and but before that you need to install the browser extension and register through this link:



Dtube is built on top of Steem blockchain though they are changing their reward system to their own Dtube token. Since it is Steem, the system is almost the same. You get rewarded if you make a comment and other upvotes it. Now this one is really decentralized that they may not keep a video storage on their own server but straight to interplanetery file system (IPFS) where you should always have a backup of your own video as they can disappear. My videos are lost which I do not know why but I suspect that my videos are not popular enough where not enough nodes are storing my videos and those nodes now are down.

Crypto Powered Gaming Platform


Rather than just rewarding players with coins for playing their video games, their implementation is more to Nonfungible Tokens (NFTs). NFTs are like ownership of digital medias powered by the blockchain. Think of it as Monalisa painting where even if you create the exact duplicate of it, it will not have much value to the original. Eventhough the quality is the same, but the fact remains that it is the people that gives them value. If people says it is not valuable, then it is not valuable even if they exactly the same. If you think that NFTs are stupid like you can just copy the digital media, you will be even more stupid if you do not accept the reality that people gives them value and not take profit. The earliest example is Decentraland where you can own lands in virtual reality currently exchangeable in their native currency called MANA.

decentraland market

Well, I do know one site that have collections of classic games such as ones in old Nintendos and Gameboys at Roller Coin. If you play those kinds of games daily, better to play at and earn pennies of cryptos. Alas, I became more busy as I get older. Eventhough I really wanted to play games a lot, I did not have the chance. Therefore, I cannot discuss about this topic much. Hopefully, I can get rich one day, so I can start switching my income from jobs to playing games like those content creators.


Earn Cryptocurrencies

Earning is the best way to get cryptocurrencies without fearing of losing its value because it is in our nature when we invest or trade, we do not want to see losses but by earning we most likely avoid that psychological problem. You can work for people who owns cryptocurrencies by doing some physical labors such as in part time jobs for example performing deliveries, sorting goods, doing errands, and even providing therapies such as massages. Aside from those activities, here are some online activities that I have experience on that can earn cryptocurrencies.

Common Tasks


I define common tasks as tasks that almost everyone can do. For examples, answering surveys, testing applications and games, and viewing advertisements. The best application that provides these tasks for me at the time of writing this book is Cointiply. In my opinion, it is like an intemediary, bridge, broker, or third party application that connects common task providers in one place. Other than its website, an Android smartphone application is available as well and hopefully for IOS in the future too. Join now at There are probably more platforms other than Cointiply, but I have not explore more especially freelance sites that are paid using cryptocurrencies.

Content Creation

Many people became content creators due to the passive income made from advertisements and donations. Nowadays, you can become an independent writer and a multimedia content creator who have your own channel. Long before I was in cryptocurrency, I was a blogger and a Youtuber. Thanks to the integration of cryptocurrencies, the income that can be made from content creating expanded.

Personal Monetization

blog layout monetization

Thanks to advertisement platforms such as Google Adsense anyone can monetize their contents meaning earning passive revenues based on the viewers of the contents. There is also another kind of advertisement platform that can monetize your hyperlinks such as AdFly. Other than advertisements, there is Patreon that is dedicated on providing platform for premium contents. Then, there is digital currency platforms such as Paypal that allows for easy donation. Today, there is cryptocurrency that expands the monetization possibilities:

  • Simpler donations where you only need to show your coin address' QR code on your contents for viewers to donate. There is also Brave and Bittube where the viewers only need to click a button to donate when viewing your contents but only in their BAT and TUBE. Very soon, web3, unstoppable domains and other crypto innovations are comming where even QR code is no longer necessary but viewers only needs to click a button. Not to forget to mention that cryptocurrency donation can be transparent, therefore anyone can see the donation transaction flow.
  • Bittube have their airtime monetization function where you only need to post a view lines of script on your contents. The result is that you are rewarded with TUBE for the viewers' time viewing your contents especially Bittubers.
  • Though Google Adsense and AdFly only pays you in fiat currencies but there are other platforms that pays you in cryptocurrencies such as MellowAds and A-ADS. The method of advertisements are also expanding such as VIDY that smartly puts advertisment videos in some words of your articles.
  • There is the controversial JavaScript mining where it is controversial because it visibly use the resource of the viewers. Eventhough advertisements is the same because the more ads and trackers adds more to the network traffic which also means resource drainage but not as visible as JavaScript mining. JavaScript mining is a monetization method where the viewers donate computational power to you for mining cryptocurrencies. A dedicated platform for this is Coinimp where all you need to do is copy the script into your contents and the viewers that opens your contents will mine cryptocurrencies for you. The controversy back then is the lack of consent for the mining where most practices does not inform viewers that there is JavaScript mining which means that viewers are not aware that they are donating computational resource which is also electricity to mine cryptocurrencies for the content creator. However, if you use it correctly, the possibilities are endless. To start of you can ask for consent to the viewers before starting JavaScript. At least inform them that JavaScript mining is implemented and how much CPU percentage was set for mining. For me, I provide an interface that allows viewers to start and stop mining as they wish and how much CPU usage they are will to contribute. An innovation example in accessing premium contents is that if they do not want to donate money, they can donate CPU usage after some time or some hash power amount as a payment for premium contents. This can be used as donation method as well where for example the amount of hash power they contribute is recorded and shown.

Most of the monetization method requires the function and allows JavaScript. These monetization will not work for example on Facebook, Twitter, and Medium. Here are some blogging platforms that allows JavaScript:

Also some online code editors:

Crypto Powered Products Previously Mentioned

publish0x earning

There are many platforms today that does not require you to configure your own monetization. They handle it for you where all you have to do is just focus on creating your contents. In this subsection is the products I have mention where previously I only state that you are rewarded cryptocurrencies for viewing. You should also know that content creators are rewarded as well:


Crypto Powered Products Newly Mentioned

In this subsection are crypto powered products that I have not mentioned because they only reward content creators only and not viewers:

Read Cash
readcash is another platform that pays writers in cryptocurrency. Currently, they stated clearly that they have no intention of storing the contents on chain and fighting against censorship is not in their scope. They do hate censorship but they simply want to focus on rewarding content creators. Their form of reward is in Bitcoin Cash because it is designed for low transaction fee. Join now at

Referrals or Affiliate Marketings

Cryptotab MLR

If you realized that at the end of each subsections, I shared my referral links to each of those products. If you used those links, I will get commissions in cryptocurrencies. That's right, in this age, sales person is not only those well dressed in suits handing flyers. Anyone can become an indipendent or freelance sales person by sharing referral links provided by the providers. Especially with cryptocurrencies, providers can generate coins or tokens before it will have any value and the borderless and permissionless system allows to quickly distribute the rewards to the sales person. In my opinion, since there are many products to refer, is better to create priorities, and as a content creator the priority of the products to refer in order from my preference are (1) demand, (2) deals, (3) profit, and (4) others.

Demanded Products

Demanded products from my definition are products that are potentially needed and are useful for customers. Examples of potential demanded products are:

  • When people asked me where to buy cryptocurrency, I redirect them to Indodax for Indonesian which is the most popular cryptocurrency exchange in the country and if they join using this link, I will 25% of their trading fee for 3 months. For those who are in Japan, I redirect them to BTCBOX and if they input HNRCWSLFLF, we all will get JPY 500 each.
  • When Indonesian people asked me about selling their cryptocurrency and withdraw them to the bank, I redirect them to Tokocrypto for desktop users, and Pintu (input FAJAR199) for mobile users because they have low fixed withdrawal fee of Indonesian Rupiah (IDR) 5000 which is around $0.4. If they use my Tokocrypto link, we each will get TKO 75, and if they use my Pintu code FAJAR199, we each will get a random reward ranging from IDR 5000 - 1000000.

Examples of potentially useful products but not necessary demanded are:


Deals are referral links that not only profits the inviters but the invitees as well. In other words, it is more profitable to buy, subscribe, or register to products using referral links instead of the regular way. Go to to see the rest of my deals, some examples are:

Profitable Products

They are not deals because they are only profitable for inviters which for me can be in form of one time reward amount, multi-level referral system, and creative referral system.

One Time Reward Amount

My next highest one time reward amount referal links after, Bybit, and Phemex, are Coinbase earns where each links, will reward me up to $40 and they will earn cryptos for learning where I collected $50 in just an hour.

Multi-level Referral System

The next one is multi-level referral system, if you know the term multi-level marketing, that is exactly it where if the people I invited invites more people, I get rewarded as well. The three products that I found have multi-level referral system are Cryptotab Browser (, Cash Magnet (, and Switch Here (

Creative Referral System

Another referral link that is fun to share is creative referral links. For example Publish0x gave me a unique refferal identification (ID) of "?a=4oeEw0Yb0B" where I can attach to any Publish0x links to refer to someone to receive commissions even if they are not my articles. For example, if I find interesting articles, I can share to my friends or post to the social media while attaching my referral ID to the articles' links, and if someone registered using that link, I will receive a commission. This feature is also provided by Read Cash, Steemit, Hive Blog, and Blurt.

Content Creation + Online Referral

As I said before, with online referral, we do not have to wear glamorous suits and sweet talk people face to face. We can use online advertisement platform or even just post on our social media. If you are a content creator, you can write articles, do podcasts, and make videos related to the products and insert a referral hyperlink within. This way, you can do affiliate marketing while adding contents on your platform to gain more views to increase to increase your monetization. This chapter itself is an example where I write an online book and have referral links in them hoping for customers. If you think further, you can even make your own advertisement by creating a hyperlink image where you make an image or animation that can attract viewers to your referral link and have them click the image and register. Note that you will be a direct advertiser where you only get revenue if viewers register to your referral links unlike being a publisher in adsense.

Almost Free Coins spin

There are sites that all you have to do is visit them and you will be rewarded in coins for doing so. They call this a coin faucet because it is illustratable as opening a faucet to get a drop of water, where instead of water you get a drop of coin. Though visit interval varies from site to site, most of them rewards you for visiting every hours and most of them are in form of lucky slot machines where you get an extremely small chance to win big for example of to $100. Other than Cointiply, here are my favorite faucets:

Active faucets where they are active in Twitter:

I have more list on Well, if you are only in for the free coins then no problem but becareful if you plan to deposit some coins to gamble or whatever because there are many scams. This section's title will close this chapter as it is called "almost free coins". Not only these faucets, but everything I mentioned here is in my opinion almost free coins. If it does not cost you electricity and Internet, at the very least it cost you your time. Whether to do this as a job is still debatable and still research in progress from my side. However, this still provides an opportunity for those who only want to get very small amounts of coins where it is not possible by buying.

Digital Currency
Thanks to the development of information and communication technology, currency can be made digital and online. Digital means that currency can be implemented on computers where processes can be automatic and fast. Online means that currency can be used on the Internet which allows transactions and other usages from anywhere in the world at anytime leisurely. Today, digital currency is used for online shops and online payments. For example, I pay my electricity, water, phone, internet, and other bills from my home using a smartphone that is connected to the Internet. I also can order items, foods, and other stuffs from my home. Digital currency can also be used to conveniently participate in the global financial system such as loans, investments, and installments.

Due to the title of this book, you probably want to ask, what is the relationship between digital currency and cryptocurrency? Cryptocurrency is just one of digital currency. Digital currency is the general category. From my knowledge, I know the following digital currencies:

  • Digital Fiat Currency: currency backed but centrally controlled by the government made digital. While for paper cashes the government needs printers to print and coins needs to be smithered, digital fiat currency can be created at a press of button on the government's server. While cashes and coins are distributed physically, digital fiat currency can be distributed digitally and online to the citizen's application. Since this digital currency is centralized, the government have complete control over. Other than being able to print and distribute, the reverse scenario is also possible which are deleting, taking back, and even denying citizen's of financial service. Example digital fiat currencies are digital dollar, digital euro, digital pound, digital yen, digital yuan, and digital rupiah.
  • Digital Private Currency: currency made and controlled by an individual or group. These currencies today are mostly scene in companies such as Amazon points, cupons, and tokens.
  • Cryptocurrency: currency based on crytographic technology which allows the possibility of distortion and manipulation resistance, distribution and decentralization, censorship resistance and unconfiscatibility, privacy, and openess.

Bitcoin The First Cryptocurrency

The easiest start to understand cryptocurrency is to understand Bitcoin. Bitcoin is the first cryptocurrency created by Satoshi Nakamoto in 2008. The ideal concept of Bitcoin is to have the properties of openess, borderless, censorship resistance, unconfiscatibility, distortion resistance, manipulation resistance, distribution, decentralization, and pseudo anonymous. Disclaimer that the mentioned concept is idealized and in reality may not be perfect. Also in this book contains no technical explanation about cryptography and other technologies behind cryptocurrency because this book is inteded for users only. Instead, only illustrations or parables are provided and may not be fully accurate.

While in Bitcoin that blockchain is like a ledger that contains all previous trasactions secured from distortion or transmutability, as a user you can think of it as a history that is secured with a technology that can easily detect if there are slight changes or modifications with the purpose of preventing them. Unless you are a corrupted authoritive figure, you should agree the history should remain truthful as it is and should not be distorted. Blockchain is such a technology that prevents distortion of history where in this case preventing corruption of financial transaction.

Maybe you have heard about the latest Wirecard issue where one billion dollars was lost, or previous scandals such as seven billion dollars accounting error by Worldcom, Enron's hidden debt, or even the Charles Ponzi scheme back in the old days. If not, most probably you have heard of financial corruptions happening in your country or local area. I still remembered my teen days in Indonesia where there was Century Bank scandal. Nobody knows where the money went and the rich people who put their money their lost all their savings. I remember seeing the news that once a rich woman must know work as a laborer at any construction sites. Who knows if there were any that have to work as a maid or as a slave after losing their savings. I firmly believe in the absolute energy theory where energy does not disappear but transferred out. Obviously, the money did not disappear, someone must have taken that money. With blockchain technology, transactions can be securely recorded in details, preventing these kinds of scandals.

Distributed System
Blockchain is a good way to record history due to the mechanism that a slight change can be easily detected but unfortunately, blockchain alone is useless. If there is only one copy of blockchain in one server, how to know modifications if there are no reference? Well, you can just have backup of the blockchain or record the modification that occur but do you really trust the entity to be honest? They can just corrupt the copy and the modification record. This is where distributed system comes in. Blockchain does not only exist on one server but many servers that are distributed and able to verify each blockchains.

After inventing the blockchain and implementing distributed system, Satoshi Nakamoto invented proof of work which is some sort of mathematical algorithm to emulate working in computers as people sweat when working. By combining blockchain, distributes system, and proof of work invented decentralization where any computer nodes can process transactions and other nodes can verify. While the current financial system requires intermediaries to build trust in transactions, Bitcoin does not require intermediaries as the algorithm allows every node to reach a concensus. While the current financial system is centralized where decisions are made by the top authorities, Bitcoin is decentralized working solely on algorithm, meaning that no entity can control.

The proof of work is like a competition to solve mathematical problems which are too technical to be included in this book. If you are curious, read the 2008 white paper by Satoshi Nakamoto or find other sources. Those who works are rewarded with Bitcoin which is why the process is illustrateable to mining. This is also how Bitcoin is generated.

Open and Transparent
The whitepaper is open for anyone to read currently at source code is open for anyone to use currently on It is even possible to fork the code and start a new coin. The Bitcoin network is open for anyone to participate whether as a user, a node, and/or a miner and transparent for anyone to see. All transactions are transparent, who mines and received Bitcoin supply are known, and the total supply of Bitcoin in existence is also known and determined which is 21 million and will be never less or never more. Therefore, Bitcoin is neither deflationary nor inflationary overall.

Your Bitcoin are safely stored on the network and nobody except for those who knows the keys can access and ideally, only you should know the keys. By keeping the keys safe to yourself, no even the highest authorities can confiscate your Bitcoin. This surprisingly works well in oppressive regions where the governments who were suppose to serve the people grew corrupted in power. The private keys used to be a large complicated set of characters but now there are keys in form of seed phrases. This is also related to borderless, where you only need to remember the seed phrases in your head and you can travel to anywhere in the world without the needs to carry your funds physically and most of the time without anyone knowing. It is like keeping the funds in your brain. However, there is also a risk where if you lose the keys, you lose access to your funds forever. Therefore, self responsibility is also raised to the max.

Bitcoin uses peer-to-peer (P2P) network where for as long as there is a peer nearby, anyone can connect to the network to perform transactions or other activities. The Internet is included in this network where for as long as you have a computer device connected to the Internet, you can use Bitcoin. If you are unfortunate to not have Internet, there is still an opportunity to any broadcasting wave for example use radio to broadcast your transaction. Anyway, with the world today from almost anywhere in the world you can access Bitcoin meaning that you can access your funds.


Again Bitcoin is P2P where for as long as there is a peer node nearby, you can connect to the network even if Internet is censored. Authorities can always try blocking every nodes but good luck in blocking emerging nodes daily. If you have used any Bitcoin wallet, you probably wondered why they give many warnings of not to make mistake in inputing the receiver's address. That is because the transaction is irreversible not only to prevent distortion and manipulation but to prevent censorship. If a transaction is reversible, authorities can easily demand to reverse your transaction if they do not like it.

Bitcoin is pseudoanonymous where the anonymity depends on how you use the coins. You can choose to be identified from the start but if you choose to be anonymous, you need to know how to use the coins correctly where the basic is just not to send your coins to any address that may expose your identity. If you have to do so, then create a new address and get new coins from another source.

Bitcoin to Other Coins

Bitcoin maximalist may say that other than Bitcoin are scam coins, only Bitcoin is the truth, but in my opinion, that thinking will only cover one of the beauty of Bitcoin. The beauty of Bitcoin is that it is open source where anyone can reuse the code and modify. If anyone wants to build something different or just does not agree with some function of Bitcoin, then they can freely create another coin and take a different path instead of fighting to change Bitcoin which isn't that the same as war?. Then let the people choose which coins they prefer. The freedom to choose is one of the beautiful contribution of Bitcoin.
For remmittance, I do not use Bitcoin because currently is at least $5 more expensive. Five dollars are maybe a small amount for people in developed countries but for us in developing countries is the cost of 4-7 meals. Bitcoin maybe the cheapest option in developed countries but in places that I went to which is remmittance from Japan to Indonesia, Brastel Remit which is non-crypto is cheaper. For my case, using Litecoin is the cheapest. Although there are BNB and XRP which are cheaper, the exchanges that I used in Japan does not have them or offer only expensive rate. If your argument is that because I am using fiat, that is an irresponsible argument at least in this time because almost all of us earn in fiat. If your argument is that because I measure in fiat, I will answer because almost all items are measured in fiat for example, would you spend $5 in transaction fee to buy $1 of coffee? See Chapter 3 for more details. There is already a layer 2 solution which one of them is the lightning network but we are still waiting for the technology to develop and for merchants and exchanges to implement.

Alternative Coins
You probably have heard that there are thousands of alternative coins (altcoins) out there and are growing to millions. With many coins out there, how do we study all of them? Well there is always a way of studying them one by one but as a starting user, the simplest way is to study Bitcoin first because most of these coins have the properties of Bitcoin but with few or many twists. Here are some examples:
  • Ethereum: the first coin for decentralized application and services which includes decentralized exchange (DEX) and decentralized finance (DEFI). I heard that the story behind this that one of the founder Vitalik Buterin wanted to build these on Bitcoin but the Bitcoin developers disagree because it will spam the network and other reason. The Bitcoin developers stated that they only want Bitcoin for transaction only. This is way Vitalik Buterin went different path and created Ethereum instead.
  • Monero: the first coin that focuses on privacy and anonymity. Bitcoin is pseudoanonymous where if you send to certain addresses may expose your identity. Monero uses an algorithm to make the transaction untraceable ideally. Monero also resist application-specific integrated circute (ASIC) and graphic processing unit (GPU) mining so that regular people can have a chance to mine using their computer processing unit (CPU).
  • Stable coins: coins that are pegged to certain values usually by having the assets in reserve. Example fiat pegged coins are: USDT, USDC, and TUSD are coins pegged to dollar where one coin is worth one dollar, EURS is a coin that is pegged to Euro, BKRW is a coin pegged to Korean won, bitCNY pegged to the Chinese yuan, BRZ pegged to the Brazillian Real, and IDRT, IDK, BIDR pegged to the Indonesian rupiah. There are also coins such as DAI that are not pegged but uses algorithm to adjust themselves to certain values. An interesting type of stable coin that emerges today are commodity stable coins such as XAUT and PAXG that are pegged to physical gold.
  • Content coins: coins where the blockchain is specified for sharing social contents. The early projects are Steem and Hive where they build a decentralized blogging platform. The new ones today on this writing are LBRY and BitTube that are well known for focusing on multimedia contents. Recently new ones emerged which are Blurt and Revain
  • Various mining algorithm: Bitcoin uses SHA256 proof of work (PoW). There are many other coins using different proof of work algorithms such as Equihash used in Ethereum, Scrypt used in Litecoin, Cryptonights which favors GPU and some CPU, and Yescrypts which favor CPU. Other than proof of work, there are proof of stake (PoS) which the algorithm is based on the amount of coins locked where Peercoin is the first one to implement and Ethereum is said to migrate to PoS in the end of 2020. The other one I know is proof of capacity where it uses the amount of hard drive storage. Many more algorithms are emerging.
  • Utility coins: the properties of these coins are usually the same to many coins but they offer special services to their platforms. For example exchange coins such as CRO, BNB, HNST, AWC, TWT, KCS, and TOKOK gives you discounts if you use those coins. If you use MCO (deprecated and now just CROTernio, you can get their crypto powered debit or credit cards. You need BitTube as a payment to buy more storage on their platform.
  • Fan coins: for example DOGE is initially created as a joke currency where the label uses a cute Japanese dog called Shiba Inu (Hachiko if you know) which is intended for a fun community. If you like sports then you probably should take a look at CHZ.

There are many other coins like there are many companies out there where you need a whole team to research them all. You can legitimately get rich buy investing into altcoin because the concept is the same that you invest in good things before anybody knows. For example I bought $70 worth Statera when I saw there post and read that they are a deflationary coin on defi and when I saw that price was still steady, I estimate that they are still early and finally my Statera once worth over $200 and sold $70 to return my capital and now I'm in profit. Also altcoins are the most dangerous investment I know because new stuffs have a high risk of not surviving for example I bought almost $100 of Inmax as a random gamble and for years they have not launch their exchange and $100 plummelled to $1 meaning that I completely lost the gamble. Also, beware of scams that anyone today can make their tokens, they could even name them Bitcoin for example if you buy these named Bitcoin token it cannot be used on the Bitcoin network because they are not the same. Therefore, always do your research first.

Government and Other Private Blockchain

The governments, banks, and companies said they are interested in implementing blockchain. You often heard they said yes to blockchain but no to Bitcoin or blockchain has value but Bitcoin does not have. What do they mean? They like the blockchain and the distributed system but they do not like the decentralization, openess, censorship resistance, unconfiscatibility, and privacy. They are in control of the global financial system, implementing Bitcoin means the same thing as giving up control such as their ability to print currency, their ability to distribute to whomever they want, and their ability to enforce monetary policies.
In summary, they want to develop a currency that uses blockchain and distributed system but centralized, censored, closed, and controlled. While the general cryptocurrency are open for anyone to participate, government blockchain currency development are closed to the government only such as the distributed nodes are only governmental nodes and if there is mining then only the government nodes can mine which means that only government nodes are allow to process and verify transactions. I am not sure what their motives are but in my opinion probably to increase the security when they implement digital currency and to prevent internal corruption but still have the power to manipulate the blockchain if they deemed necessary and to have monetary control over their citizens such as who can use, who cannot, what services are allowed, and freeze or even forcefully take the citizens' balance when necessary. What about company blockchain? Like Facebook Libra, while government blockchain are closed to the government, company blockchain are closed to the company where the company decides who can enter the space and have control.

Correlation to Our Lives
Now that you know how amazing Bitcoin and other cryptocurrencies are but unless you are hobbyist, follower of economic news, or have faced financial turmoil before, you probably asked, what does cryptocurrency have to do with our lives? In rough questions are so what, what about it, and then what? You maybe living very well right now. You have a large amount of cash in your pocket and balance in your bank account and you can buy what you need or even what you want and now, you are even fasinated that you can swipe your debit and credit card anywhere for payments or you can purchase online. Then, why do you need cryptocurrency? For starters, there are people out there that are not as fortunate as you such as people who have their local currency value destroyed, denied access to banking or banking services are just not available, have banking but currently restricted due to oppressive authorities, or in anyway denied participation in the global financial system. Mainly cryptocurrency are for these people. Other than that, cryptocurency are for developers, visionaries, supporters, opportunist, educators, tech geeks, speculators, and more. To truly understand cryptocurrency, it is necessary to know about the previous and current financial system.

Financial Value

Most of us are probably born with fiat currency or public simple term cash accepted as money which is a tool to communicate value. Simply with money you can buy anything and most of us believe that money is our primary necessity which is not true. Money is just a tool, it is what we can get with money is our true necessity. If you cannot understand that, then you lack history lesson or logic. Ask yourself a question, does money always exist in the past? The answer is no. If you go back in time and give people dollars, they would think you are crazy. Why would they give you stuffs for a piece of paper?

The oldest form of trading is barter. I need water and you need food so I trade some of my food with you to get some water. However, barter have scaling, practibility, and divisibility problem. I have food but not everybody needs much food, you have clean water but not everybody need much water, and someone have clothes but not everybody need much clothes. I need clothes and found someone who has that also needs food. I have to negotiate how much food to give and how much clothes that person will give. Very impracticle and people began to demand a single unit that can measure the value of every item or an item called money that can buy anything.

People began experimenting with salt, sugar, crops, shells, and other commodities as currencies but only one type was admitted through out history and that is precious metals. Mainly gold and silver have the property of immutibility which means no one today can create gold, you have to mine gold. This means today that gold is scarce which is known to have limited supply. The property of gold also cannot deteriorate which the form of gold you have now will remain the same almost forever which indicates a good commodity to store. Gold is divisible where items can be valued in weight of gold for example a meal is worth a few miligrams (mg)s of gold. People began to create gold coins that makes trading much more practical then before.

In my opinion, for average people, gold was doing well as a currency but gold was not practical enough to be used on nation scale for example it is very heavy to carry for massive transaction not forgetting to mention costly as well and risk of being raided or anything that can lose the physical golds. Dividing gold is still not easy for regular people where you need smithing which means that there is a limit to the divisibility. Say that I carry a few mg of gold but I only want to buy one candy, usually I cannot but have to purchase many candies or other items.

This is where paper money comes in. Instead of carrying heavy gold, we trust banks to store our gold and receive a certificate or a kupon where each of them represents an amount of gold. That is the good dollar I knew, where each dollar can be exchanged to fixed certain amount of gold. Paper money are easier to carry and easily divisible and vice versa. It is also practical enough to be used as a medium of exchange on a nation scale. Then comes banking, the digital age, and online transactions and you know the rest.
Everything is well when the government and their partners are righteous but what if they are not? In 1971, Nixon ends the Breton Woods system by taking the Dollar of the gold standard. This means that the Federal Reserve will no longer exchange the fix amount of gold to the Dollar. The deeper meaning is that they can print as much Dollar as they want whilst previously they need the gold to backup the printing. At least they should have some goods to backup the Dollar but they do not and print out of thin air. Now, they have the capability to do quantitaive easing. Although the intention is noble which is to stimulate economic growth, the reality is indirectly forcing you to fund their projects. You should agree that donation cannot be forced nor without consent.
Most of us in the open crypto world are sarcastic of banks at that with similar statement of why should the banks be afraid of taking risks if there is the government to back them up? If they win huge profit in their investment then most of the profit is theirs but if they lose then the government will save them by printing fiat currency in giving it to them and do you even know what that means? That means devaluing the cash that you hold which is the same as giving pieces of the cash to them. Logically, is not the government who bailed out the banks but you the citizens who bailed them out except for those who sold their cash and bought physical goods. Think of it like this, you worked hard in a gold mine to get physical gold and then there are many alchemists who can create a lot more gold very easily from nothing. Usually the amount you mined is enough to get a decent amount of food but these alchemists also needs food. These alchemists offers a lot more gold for the same amount of food that you demand. Now, who will the food seller sells the food too? Ofcourse the alchemists, now it is the norm that food cost a lot amount of gold, how much food can you get? Almost nothing, all that hard work in the gold mine suddenly becomes useless since the birth of many gold alchemists. This is what you call inflation. The Dollar and other fiat currency are now the same, where the federal reserves, central banks, or government are now the alchemist. They can create cash as much as they want give them to whomever they want.
In the banking crisis of 2008, they perform alchemy and transmute papers into Dollars and give them to the banks. Bitcoin might not have been invented if they bail out the citizens instead of banks or the least just let everything collapse, accept their mistakes, and build a new better system. If you see the message in Bitcoin's genesis block which is the very first transaction, it states discontent of the second bail out. The exact message is "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks". In my opinion, Bitcoin was a protest for the government's irresponsible control of the fiat currency so Bitcoin was invented as a currency that no one can control or politisize.

Before proceeding, let us take a look at some other currency debasement history. Most of the information I got from Guide To Investing in Gold & Silver by Michael Maloney and I strongly recommend watching his Hidden Secrets of Money Episode.
The fall of the Roman Empire in this perspective is caused by the overfunding of conquering other regions where the government ran out of funds. They started by debasing their coins by embedding less gold and silver and ended by forcing the merchants to lower their goods' and services' price. Naturally, the economy fell. Before the Roman Empire, there was Athen where they also find a clever to overfund the war by mixing 50% copper into their gold and silver coins and perform deficit spending.
It is known that the first paper fiat currency emerges in the 1370 during the Tang Dynasty in China. Merchants who does not accept the paper currency receives the Death penalty. Not long afterwards, it went into hyperinflation.
Around 1716 France was in great debt that even the taxes could not cover the interest. John Law proposed paper currency and economy prosper and everyone lived in great wealth. However in the end, the system began to collapse when a royal exit the system by redeeming their paper currency to gold. Then everyone started to follow, if there were no gold then silver were given, and if there were no silver then copper were given until everything collapse. The paper currency did save the economy at one time but they blew it up by irresponsible spending and more printing, or they are just living in delusion that they are using imaginary assets or in my opinion future spending power, or the reason they succeeded in the begining was quitely and indirectly they were using the wealth of the citizens by printing more currency which is actually the same as increasing the taxes many times fold but the citizens were ignorant of the truth.
At the beginning of World War 1, Germany conducted heavy currency printing out of thin air but inflation was slow to follow. This was because of dire times that the civilians were conservative therefore, less currency in circulation, and they believed in the currencies purchasing power so they save them meaning higher demand for currency and less demand for goods and services. When times got better, the demand were reversed. Everybody wanted to spend and in no time hyperinflation followed.
After the 1900s, the Dollar and similar fiat currency went through similar events which are overfunding of wars. In the end, they exit the Breton Woods system by cutting the Dollar off the gold standard. Today they can print as much fiat currency as they want. As the previous explanation about the 2008, the authorities decides who should be rich and who should be poor like a deity deciding who lives and who dies manipulating the natural law of the free market which was no doubt unfair.
Even today, Zimbabwe is still a well known case of hyperinflation where they print their fiat to oblivion that you can even find markets selling mountains of cash as souvenir. Today, Venezuela is in the lead for hyperinflation.
Bitcoin and other cryptocurrency can be a solution because their supplies are transparent and more fair than the current fiat currency. However, there are other solutions for this issue. The oldest form of money that have survived for centuries are precious metals such as gold and silver. If your goal is only to preserve your wealth, then buying gold and silver have proven to be a great solution historically. Other than precious metals, you can go back to the basics of money and ask the question of why you need money in the first place, and that answer is because you want to buy goods and services. Simple examples are stocking food supplies, have shelters which include houses, and buy items that you need and items that you think will be useful in the future. To go further, start being self sustainable such as grow your own fruits and vegetables, build a farm, secure your own water supply, or even build your own electricity source such as using solar panels, wind turbines, and other renewable energy sources. Once you become smarter, you probably want to start your own business instead of just holding those cashes.

Financial Freedom

This book does not emphasize cryptocurrency as a solution to financial value. You can find gold bugs in agreement with Bitcoin activists regarding the problem with the current financial system but does not agree with Bitcoin especially other cryptocurrencies mainly because they do not have physical form and many other reasons. Like this book stated previously that if the problem is only financial value, there are other solutions which proof historically effective. Eventhough these years Bitcoin and some cryptocurrencies have the best performance, regular people cannot handle the short term volatility. However, before the purpose of tackling financial value, Bitcoin and other cryptocurrencies are created for a larger purpose.
In my opinion, on the creation of Bitcoin in 2008, the value loss of fiat currency was not the primary problem. The primary problem is the global financial system heavily controlled and maybe politisize. Remember that the current local currency that we hold are no longer backed by any value and the central banks along with the government can print as much as they want, and remember that that kind of printing is taking value from you and giving them to others. They can decide who gets wealthy and who gets poor. I am aware that I am bashing the authorities one sidedly. If I were in their shoes, what would have I done differently? I do not know but this book is mainly for you users and citizens. I believe to put my friends, families, and myself higher priority than the nation, it is the default nature. Wise people immediately escape to precious metals and other assets but do you know that often when a country's financial system is about to collapse, they implement strict monetary policies. This book is about how to save yourself when they abuse the fiat system and not about whether their decisions are right or not. In fact, I do not really care about debasement, printing out of thin air, counterfeiting, inflation etc but I care about the freedom to utilize and manage our own wealth however we want or to join and exit the system whenever we want which is why I am in cryptocurrency. The previous subsection discussed only the intial phase of falling economy which is debasement. When debasement starts to fail, the following usually happens which happened in all the debasement examples of the previous subsection:
They may demonetize bank notes. Although theoretically there should not be any changes but in reality may indirectly affect the citizens. For example in India 2016, there were shortage of cash, long bank queues, and short deadline where there were citizens who did not have the opportunity to exchange their bank notes. This means they are now holding useless paper cash which means they got their wealth stolen indirectly.
They will start to ban exchanging and trading assets other than their fiat currency, for example they banned transactions in gold and other foreign currencies such as the Dollar. Other examples that are happening during the writing of this book are China discouraging its people from buying precious metals, FDIC discourage you from withdrawing cash from the bank, the global stock market closes temporarily during the black swan event due to COVID-19, and more severe example is Zimbabwe permanently shutdown its local stock market accusing it to be responsible for the collapse of their fiat currency once again and also they block all electronic and mobile payments.
They implement stricter travel rule for example rumors of China not allowing its citizens to bring their wealth outside of its country without the government's permission.
When it gets worse, they force exchange your assets into their fiat currency such as the Executive Order 6102 that confiscates citizens' gold.
Even worse is the Corralito Affect in Argentina where they frozed the citizens bank account forcibly covert 1 Dollar to 1 Peso which then they released the peg and immediately 1 Dollar became 4 Peso and got more expensive. The worst case is that they truly confiscate or seize your asset like how Cyprus in 2012 seize bank deposits where seizing only normally happens to criminals.

The last thing that they will try to do is to force control the price of the market to their fiat currency. This happened a few years later in the United States after President Nixon no longer supports the convertibility of the Dollar to gold. The worst was near the end of Roman Empire where they released a law that citizens are forced to work and continue family business but at a controlled price punishable with Death.

With Bitcoin and other cryptocurrency, regulatorily can be banned but technically cannot be stopped or censored, technically cannot be confiscated where the only way is to persuade, pressure, or social engineer the owners to hand over themselves, both the supply function and distribution are algorithmicly and mathematically defined which ideally is neutral and not controlled by any single entity, and also most are open and transparent.

Wide Adoption Have Not Started
Eventhough cryptocurrency can potentially be a revolution in finance, is still only a potential. This means that you cannot switch from the current centralized fiat system to the new decentralized system like flicking a switch or changing a bit from 0 to 1 and vice versa. This is because the age of decentralized finance has not yet come.
Unless you are in a specialized region, you will have a difficult time living if you sell all your fiat currency to cryptocurrency. Like the fiat currency (dollar, pound, euro, yuan, yen, etc) that you hold, cryptocurrency is just a tool to express value. Your true desires are not these money or currencies, but the goods and services that you can obtain with these such as food, water, shelter, and luxuries. Although the value of cryptocurrencies rises in terms of fiat, it is not enough adopted. People still prefers to trade in paper currencies such as it is hard to buy items with cryptocurrencies while anyone are willing to accept your dollar for items. Therefore, you need a bridge that can quickly and easily switch between fiat and cryptocurrencies.
The simplest bridge that you can find are people who are will to buy and sell cryptocurrencies. Next in line are merchants who are willing to accept cryptocurrencies for payments. However, they are difficult to find for now as cryptocurrency is still in a socialization phase. The easiest bridge that you can find today are online 3rd parties that are willing to buy and sell cryptocurrencies.

Crypto Debit and Credit Cards
Another way to spend your cryptos are by using cryptocurrency powered debit and credit cards. The simple mechanism is first you power your cards with crypto coins and second use the card in any stores and automated teller machines (ATM)s that accepts VISA and Mastercard. You can also shop online for as long as they accept VISA or Mastercard powered debit and credit cards. I know only three, so please comment if you now more.
  • Today, is globally on the center stage for crypto powered debit and credit cards. Many people trust them, they support many coins, and they have other great services. Also they are big and are very good at marketing. Their card offers many cashbacks and discounts where for crypto enthusiast, the cashbacks are in crypto coins. The best deal I can offer you is by registering using mine or other's referral link where if you input q4pv8f6y8t in the referral section, not only me but also you will get a $50 welcome bonus in MCO. Although you need to apply for a Ruby Card by staking 50 MCO for 180 days to unlock your welcome bonus. Well, if you are rich, you can stake more MCOs and apply for better cards. Currently the card ships in US, EU, UK, and New Zealand, and more countries are coming soon.
  • Ternio Block Card. If I'm not wrong, I found this from advertisements which is also a debit card that you can power with few cryptocurrencies. You can get cashback in crypto tokens as well. Use my referral link and deposit $100 and we both will receive $10. There is a monthly service fee, therefore do not deposit if you do not plan to use.
  • Vandle Card Japan. In Japan, my friend found a debit card called Vandle that can be topped up using bitcoin or bitflyer. This card is challenging for foreigners because it is all in Japanese, so get help from Japanese or use translate app.
  • Coinbase Card. Coinbase also releases a card and use my link to get $10 bonus after exchanging $100. They are available in Austria, Belgium, Bulgaria, Croatia, Cyprus, Denmark, Estonia, Finland, France, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, and the UK.

Fiat Digital Wallet
The hottest news currently is that Paypal and Venmo plans to provide buying and selling bitcoin in their services. I admit that I rarely heard about fiat digital wallet that supports direct bitcoin exchange. For now, I only heard about the following:
  • You can deposit and withdraw using OVO in Indodax.
  • You can deposit to OKEX using Gojek.
  • LINE Japan made a patnership with BITMAX.
So leave a comment if you know more.

Find other adoptions and leave a comment if you know more.
  • You can buy gold and silver using BTC in
  • You use Moon Browser Extension to shop online such as on Amazon and Ebay with BTC and some other cryptocurrencies.
  • Indogiving collaborated with Tokocrypto to accept donations in cryptocurrency and below is my experience:
    • 00:00 Opening
    • 00:20 Indogiving website
    • 00:30 Finding cause to donate
    • 00:40 First donation in ETH
    • 01:15 Sending ETH to the donation address from Indodax wallet but does not work
    • 02:25 So I have to rally to Tokocrypto and does not work either
    • 03:30 So tried using Binance wallet and succeeded
    • 05:05 Input the TXID as the proof of payment
    • 05:30 But it failed
    • 06:30 So I contacted the support
    • 07:00 Finally succeeded and a lesson not to use exchange wallet for transaction
  • Software services such as VPNs, phone credit, musics, videos, subscriptions, games, etc. Another one is crypto related goods and services such as miners and a t-shirt with Bitcoin logo. Below is my experience paying my friend's online course using Bitcoin:
    • 00:00 Africa Blockchain Alliance Developer Program
    • 00:25 Payments that they accept
    • 00:50 Choosing Bitcoin payment
    • 01:24 Bought Bitcoin at Coincheck Exchange
    • 01:35 Pay from Coincheck Exchange (Withdraw)

    • 10:00 Exploring their website more.
    • 11:40 Check delivery status.
    • 13:15 Delivered and unpacked.

Centralized/Custodial Exchanges
For common people who have bank accounts, the easiest bridge for them are centralized or custodial exchanges because they supported crypto to fiat exchange and fiat withdraw to bank accounts. Another reason is because the system is still similar to the current banking system which means everybody is familiar with them, while decentralized exchanges are something that most people do not yet understand. The best exchange to start with is the nearest to you for example, if you can visit their office, then that's probably the best starting point. At the very least, find an exchange that is in your home country and your country of residence.

Remittance Example
This figure shows an example of remittance for those who does not have cryptocurrency. If you already have cryptocurrency, you can skip 3 steps. The steps are:
  1. Deposit your fiat currency into a bank.
  2. Deposit/transfer that fiat currency to a cryptocurrency exchange.
  3. Buy a cryptocurrency.
  4. Withdraw/send that cryptocurrency to a cryptocurrency exchange in another country.
  5. Sell that cryptocurrency to the country's local fiat currency.
  6. Withdraw/transfer that fiat currency to a bank in that country.
  7. Withdraw cash from the bank or ATM.

Exchange to Start

My home country is Indonesia where I have most of my identifications and accounts and most likely I will stay there often so for my case I will register for cryptocurrency exchanges in Indonesia such as Indodax, Tokocrypto, Upbit, Luno (input "S24B5E" in referral to get your bonus), Pintu (input "FAJAR199" in referral to get your bonus), Zipmex, Tokenomy. If you are staying in your home country then you can finish your starting phase up to this point but for me, I'm currently studying in Japan therefore, is a good choice and also an opportunity to register to exchanges in Japan. For now only registered in Coincheck, and BTCBOX (input "HNRCWSLFLF" in referral to get your bonus).

Why should you start with the closest first? Because they are centralized or custodial which means you are giving your funds to them and trusting them that they will manage your fund properly. The moment you give them your funds, they can take it and use it as they wished, which is why trust is very important and is the weakness to the current system compared to the new decentralized system. There are many variables that builds trust such as being regulated, many users, good reviews, clean history, and among them is physically close to your distance where if anything happens to your funds, you can just visit their office.

Example Usage Guide

Actually this post is for my friends and maybe potential future seminars that I will host to introduce cryptocurrency to new people. I will give an example guide of using one of the exchanges in my home country which is Indodax and one of the exchanges in my country of residence which is Coincheck. However, once you know how to use one of them, you mostly likely can use the rest with few difference because they may introduce different functions but the basics are:

  • Have an email address and prepare your identification documents.
  • Opening their websites, registering, verify email address & mobile number, login, explore, etc.
  • Deposit and withdraw cryptocurrency.
  • Deposit and withdraw fiat from or to bank account.
  • Buy and sell coins instantly.
  • Read charts, orderbooks, and bid prices in an auction-like market.

Finally, the fees that you need to check whether there is or not:

  • exchange rate
  • deposit fee
  • withdraw fee
  • trading fee
  • other transaction fee

You can check on their websites because they can change for example Indodax's fees: and Coincheck's fees:

Simple Indodax Guide

Indodax Registration
1. Prepare your identity cards, your email address, paper and a marker, and visit Fill in your desired username, email address, desired password, and phone number.
2. You will get an email to verify your Indodax's email address. Click the link.

Indodax Verification
3. If not automatic, go to menu and profile, and fill in your profile. Finally, click the verification button.
4. Fill in the form and upload your identity card.
5. From Indodax, take a selfie like on this image and upload. Wait for their instruction and if all is well, then you are fully verified.

Indodax Deposit and Withdraw
6. Go to wallet either on the top or left menu.
7. To deposit or withdraw Indonesian Rupiah from or to bank, choose IDR and the deposit/withdraw menu.
8. If you don't have any coins, you can start buying here but before that you have to deposit Indonesian Rupiah. Just find the deposit button and follow the instruction and finally find the confirmation button to confirm your transfer.

I also made a video of depositing IDR from OVO digital wallet if you are interested:

  • 00:00 Opening
  • 00:12 Already in Indodax website
  • 00:35 Click wallet menu to find OVO deposit menu
  • 00:38 Choose IDR
  • 00:41 Choose deposit
  • 00:51 Choose OVO
  • 00:01:00 automatically use registered phone number
  • 00:01:10 receipt issued to OVO application
  • 00:01:35 final result
9. Now one of the highlights of this chapter is to withdraw fiat to bank account where in this case is Indonesian Rupiah. Just click the withdraw button and follow the instruction. If you are still in coins and don't have IDR, you have to sell your coins first.

Here I successfully withdrawn my IDR to my Bank Negara Indonesia (BNI) account. In Indodax, the IDR withdrawal is fast where for me took only an hour or two but the fees are high which is 1% and minimum 25k IDR.

  • 00:00 IDR withdrawal menu.
  • 00:27 Input amount, bank name, and account number.
  • 02:35 Confirm through email.
  • 03:20 Withdrawn successful proof.

Another example is that I withdraw using Luno (input "S24B5E" in referral to get your bonus). It's cheap with only 6.5k IDR but took almost 3 business days although they stated that it should only took 1 business day.

  • 00:00 0 deposit fee for other than BTC
  • 00:11 0.0001 BTC deposit fee
  • 00:21 Send BTC from Exodus to Luno
  • 01:16 Exchange BTC to IDR
  • 01:36 Add bank account
  • 02:02 Request IDR withdrawal to BCA
  • 02:38 Withdrawal successful with 6500 IDR fee but took 3 days
10. To send or receive coins, choose the desired coins and follow the instruction. The method is the same as chapter 2 of how to send and receive cryptocurrency by copy and pasting the address or scanning QR code and make sure to double check as the process is irreversable.

My example of directly withdrawing Raven Coin that I mined in MiningpoolHub.

  • 00:00 MiningpoolHub withdraw menu.
  • 00:37 Registering Indodax account receiving address.
  • 02:10 Request withdrawal.
  • 03:12 See transaction history.
  • 04:20 Withdrawal successful.

Check Other Menus
11. Check other menus yourself:
  • Security: set password, phone number, 2FA, etc.
  • Mobile App: help page to mobile app.
  • Trade API: for 3rd party program such as TabTrader or writing your own program.
  • History: see your transaction history
  • Affiliate program: get commission for referring other for example my referral link is
  • VOUCHER: the only way I know to send IDR between Indodax and Tokenomy members without fees.
  • Help and other menus: just visit yourself

12. If you only want to buy and sell bitcoin instantly using IDR without complicated methods than just go to "Buy/Sell Bitcoin Instantly" menu.
13. If you want to get other coins or trade then go to market, choose a coin to trade, and you will greeted with a price chart.
14. You are on an auction like market where you bid prices. You need to get familiar with the order book. This is where sellers and buyers book prices. You can see the latest price sellers offers and buyers bid, and how much supply and demands there are.
15. Once you read the chart and the order book, now you are ready to trade. The "instant" option means you accept the latest price and trade instantly, while "limit" you set your price, usually you want to book cheaper price for buying and more expensive price for selling. You then wait hoping that someone accepts your offer. "Stop" loss are for traders who trade only to seek profit and it is an option to cut their losses.

Simple Coincheck Guide

Coincheck Registration
1. Prepare your identity cards, your email address, paper and a marker, and visit Fill in your desired username, email address, desired password, and phone number. You will get an email to verify your Coincheck's email address. Click the link.

Coincheck Verification
2. If not automatic, choose the person icon, and fill in your profile. Finally, click the verification button.
3. Fill in the form and upload your identity card. Take a selfie with your identity card. Exchanges in Japan are stricter than in Indonesia. Additionally, you need to upload a document that proofs your address such as electric bill and official letter from local government. The more you are rejected, the harder the requirement gets until you are asked to take a video of yourself. If you are not a Japanese, it can be extra challenging as you are required to write your name in Katana and if you are living in Japan, you are required to write your living address exactly in Japanese character as on your identity card.

Coincheck Deposit and Withdraw
4. To deposit Japanese Yen from bank, choose main menu, then wallet, finally deposit. Usually there is no fee once a month if you transfer from the same bank as they requested, if not, it usually cost ¥440. You can also transfer from convenient store in Japan and also use paypay, although they are more convenient but usually more expensive.

I also made a video of depositing JPY from Japan Post Bank for foreigners in Japan:

  • 00:00 You need to pass know your customer (KYC) first.
  • 01:25 In website, go to wallet and choose deposit Japanese yen.
  • 02:19 A detailed instruction of where to transfer.
  • 02:40 Go to JPPost Bank
  • 02:54 Choose Remmittance.
  • 03:05 Input pin and choose other bank.
  • 03:20 Input "su" and find SBI, then "ho" and choose account.
  • 03:45 Insert the account number instructed on the web.
  • 04:05 Input deposit amount.
  • 04:20 Do not use your default name, change to user id etc as instructed.
  • 05:55 Input your phone number.
  • 07:35 Deposit successful.
5. To withdraw Japanese Yen to bank, choose main menu, then wallet, finally withdraw. Register your bank information, there's a fee for withdrawing, and finally press withdraw button after filling in your desired amount.
6. To send or receive coins, choose send or deposit coins, then choose desired coins and follow the instruction. The method is the same as chapter 2 of how to send and receive cryptocurrency by copy and pasting the address or scanning QR code and make sure to double check as the process is irreversable.

I made an example of transferring coin from Coincheck to Indodax and also possible fees if remmitting JPY to IDR from Japan to Indonesia:

  • 00:00 Send BTC from Coincheck to Indodax
  • 03:35 Fee calculation
  • 08:40 Sell BTC to IDR


If you prefer my video explaination:

  • 00:00 default trading page
  • 00:30 buy and sell coin instantly
  • 00:40 chart, orderbook, etc.
  • 02:00 demo trading.
  • 05:40 open order.
  • 07:50 demo instant coin buy.
  • 10:30 coincheck's beautiful trading view.
7. If you only want to buy and sell coins instantly using JPY without complicated methods than just go to "Buy Coins" or "Sell Coins" menu. It's the opposite to Indodax where Coincheck have many coins for instant transaction and only Bitcoin for trading.
8. The default home menu at top takes you to trading Bitcoin. The chart is on the separate menu, but for me, I prefer using the tradingview for trading.
9. Coincheck's trading view is one of my favorite function. You are on an auction like market where you bid prices. You need to get familiar with the order book. This is where sellers and buyers book prices. You can see the latest price sellers offers and buyers bid, and how much supply and demands there are. Once you read the chart and the order book, now you are ready to trade. The "instant" option means you accept the latest price and trade instantly, while "limit" you set your price, usually you want to book cheaper price for buying and more expensive price for selling. You then wait hoping that someone accepts your offer. "Stop" loss are for traders who trade only to seek profit and it is an option to cut their losses.

Enter With a Wallet
You may have been regularly following the news and you may have been diligently following the price. A funny story from a student of Ivan on Tech Academy, that student learned how to program smart contracts and other cryptocurrency related technology but do not know how to buy coins, receive coins, send coins, and use coins. This chapter will guide you of how to enter cryptocurrency space.
To enter the cryptocurrency space, you need a medium that can receive, send, and perform other interactions with those coins. A simple medium is called a cryptocurrency wallet which you can carry to anywhere in the world. The first category division of a wallet is divided into three either custodial, semi-custodial or non-custodial.

Custodial Wallet
A custodial wallet is basically cryptocurrency served to be as similar as the current banking system. You do not want to hold the responsibility of securing your own coins. Therefore, you store your coins into a cryptocurrency bank and trust the bank to secure your coins. Another reason why starters prefer custodial wallets is because of the support. When the user have problems with the interface, exchanging, depositing, withdrawing, and even when they lose their password, the support can help them. When anything goes wrong, the users can even blame the support and may even get refunds. A good custodial cryptocurrency bank for starter is Coinbase. Not only they try to make it as simple as possible for you but educate you as well so that one day you are ready to handle non-custodial wallets.
One user feature that remains the same in custodial wallet is the users' perspectives transaction mechanism or the send and receive coin function. The transaction process remains irreversible where if you input the wrong address even with the smallest typo, you will lose those coins forever. That applies when to transactions between the custodial wallet and the outside wallet while for internal custodial wallet, they can fix your mistake because it is internally controlled. In the past, custodial wallets always gives warning about to be careful when typing an address before sending or receiving while non-custodial wallets does not give warnings at all where starters are often lose their funds because they are not careful when typing addresses. Some custodial wallet have an advance feature of detecting address typos.

Semi-Custodial Wallet
A semi-custodial wallet is wallet where both you and the third party have the keys to your funds. The purpose is to ensure that you can recover your keys whenever you lose them while at the same time trusting the third party to secure your keys and not be irresponsible with your funds. For now, I only know one type and that is a web wallet where you open a website which is a wallet service where you can register, input your username and password to use the wallet but they also let you have the keys. However, the semi-custodial that I described I cannot find or have not existed yet. The current semi-custodial wallet method that I know is where the third party stores only the encrypted keys and needs your password to decrypt them. They do not store your password where if you forget your password, the keys are the only way to restore your funds. They called this, hybrid wallet. There are also non-custodial web wallets where they just provide the interface to access your wallet sparing the necessity of installing a wallet application on your computer device. Usually, you need to import your keys everytime you open the web wallet to access your funds.

Non-Custodial Wallet
Non-custodial wallet is the original concept of cryptocurrency. While custodial wallet keeps your funds in the custody of third party, non-custodial wallet returns full authority and ownership to you. This concept was introduced because people are losing trust with third party where they act irresponsible to their customers' funds. This concept is also for those who are in oppressive region where the authorities becomes tyrants, telling you what to do with your assets. With non-custodial wallet, the concept is no one other than you can access your funds that includes even the highest authority. Your funds are unconfiscateable and they have to torture you to get them. However, the responsibility is also to the max where you are solely responsible. If you lose your keys then you lose access to your funds forever or if you do not secure your keys well, someone can steal them and steal your funds.

Hot Wallet
People often call this hot wallet which is a wallet that requires Internet connection to function. Well you can think of this as an online wallet although hot wallet is more appropriate because the keys are not stored online but should be safe with you and online usually refers to anything that is accessible on the world wide web (www) which is rarely the case for hot wallet. Yes, there are wallets where you can access online where the keyword is web wallet but most of the hot wallets are downloadable applications on your computer devices. For starters, I very recommend to try hot wallet first because it is user friendly and the reason why they require Internet connection is so that they can access, manage, and sort your funds faster. Also, I recommend Exodus wallet because it has a good user interface and support many coins and below is an example of using Exodus wallet:

Backup and Secure Seed Phrase and/or Private Keys
The first thing that you should do after creating a wallet is to backup and secure your seed phrase or private keys. The reason why you should backup them because if you lose them, you will lose access to your coins forever. The reason why you should secure them because if anyone knows them, they can steal your coins anytime. However once again from the previous chapter, the advantage is that you fully control your coins that no one even the authorities can confiscate as long as no one knows your seed phrase or private keys. To get your seed phrase in Exodus Wallet, find the backup menu. In the new version, you go to settings and choose the backup navigation menu.
Usually you get few words, so write them on the paper or print them out and put them on your locker or vault or anywhere safe. You can also store them on your computer but beware of hacks, malwares, and virus that can steal that seed phrase. The best case is memorizing them and never forget because the brain is currently the best place to secure things. Warning, I showed the phrase here only for educational purpose and anyone can steal the fund in this wallet because I showed it in public. In fact, I once tried putting some coins and immediately they were sent to an unknown hacker's address. Once your seed phrases or keys are leaked, immediately create another wallet, move all the coins, backup and secure the seed phrase and/or private keys, and abandon the leaked wallet. In the last part of the video, I demonstrated how coins can be stolen if the keys are leaked.
If you need the private keys of each coin address rather than the whole seed phrase then go to home, then wallet, click the desired coin, go to top right menu, and export private key.
Once you got your seed phrase and/or private keys, you don't need to worry about you computer device being broken because you import the keys into other devices and access your coins.

Sending and Receiving Coins
The other basic function is the sending and receiving coin function. Go to the desired coin and find receive button or downward arrow icon for receiving coins or find send button or upward arrow icon for sending coins, and click. If your desired coin is not on the list then click the plus (+) button or go to settings and find assets to add your coin to the list. If you still cannot find it, then you need a different wallet, search on Google for a wallet of your desired coin.
For receiving, you can find your public address in form of complicated characters which are these characters that you need to share to receive a coin. Here, you are provided with a clipboard function for copying and pasting the address and a QR which you can choose one or use both them. Those functions are there to prevent human errors in sharing the address because one character mistake can result in coins to be lost forever since transactions are irreversible, also if you share the wrong coin address (for example the sender wants to send you Ethereum coins but you share your Bitcoin address) will also result in coins to be lost forever. Always double check, even triple check is recommended. There are many places to share your address such as your blog, social media, for donation, and you can print it out put in on your store to receive payments.
For sending coin, put the payee's public address on the address section. Again use copy&paste or QR code and double check to prevent human errors and phisings because transactions are irreversible where you should also carefully check the amount like not make a mistake like putting an extra zero. Usually, you are charged with a network fee. Once you checked again and again, then send.
A transaction hash (TxID) should be generated where you check the status of transaction on any blockchain explorer of the respected coin. How wallets today are usually user friendly enough that you can click the TxID which will redirect you to the transaction status. This TxID is enough to be used as a receipt since it contains the details of the transaction. If your wallet is not user friendly enough, you can search on a search engine for example on Google you search for "Bitcoin blockchain explorer" and choose an explorer and insert the TxID on the search box.

Built-in Exchange
Some wallets have built-in exchange for you to exchange coins for example in this image shows exchanging BTC to USDT. This is a good function where very soon, all wallets will have built-in exchange.

Other Functions

The necessary functions of using a wallet have been discussed. Explore other function yourself. I may cover interesting functions in separate articles.

Other Hot Wallets Types
The Exodus wallet demonstrated in this book is a stand alone application installed wallet. There are other more convenient wallet but unfortunately today, the more the convenience, the more the security risk. Therefore, I do not recommend to store a large amount of fund here. Only use these wallets for trials and fast transactions. Another type of wallet is an extension or plugin wallet for example this image shows that I installed Guarda Wallet on my browser. If you are a browsing maniac where you are too lazy to install anything, then you can try web wallet where you just need to type the web address for example Guarda also have a web wallet at This is convenient for those who used full browser operating system such as Chrome OS. Ofcourse, since these are still non-custodial wallets, you still keep the keys.

Cold Wallet
A cold wallet is a wallet that does not require Internet connection but more accurately, is wallet that keeps your keys offline. By keeping your keys offline mitigates the risks from online malicious activities which should be safer that hot wallet. This does not only apply to keys but to any digital data that you want to keep safe. An example wallet is Electrum which is a cold storage wallet where you can open it offline but if you are online in default connects to the Internet.

Paper Wallet
As the title of this subsection, a paper wallet is a wallet made out of paper. It contains your public address to receive coins and your keys to send coins. Well, I stated that the public address can just be shown on the cashier to accept cryptocurrency payment but how do you use the keys that are on the paper? You can have a one time smartphone application for example that scans the QR code of the key each time you want to send coins and after successful transaction, the key information on your smartphone is destroyed meaning that the key will not be stored on the smartphone. It necessarily does not have to be a computer device connected to the Internet, but anyway to connect to the network and use the keys to send the coins.
You can always study the theory and perform mathematical calculation yourself to generate a public address and a private key but this book will not be 101 for users anymore if that is the case. You can start by search on the search engine such as Google and Presearch about "paper wallet generator". Extra, try to find more information about the website that you chose by reading them thoroughly, ask a trusted friend of yours, search whether they are scam or not, and try searching the social media.
After you chose a website, for example here I chose which is the oldest paper wallet generator with no issues up to now. You can always just visit the site and save page as but the domain can change ownership where there is no guarantee whether the owner is not a malicious. Therefore, I suggest to open the link to their source code and download the .html file or the whole code there.
Turn off your Internet connection and open the .html file using a browser where I recommend you do it incognito. For starting users convenience, I demonstrate in Windows but if you want stronger security, I suggest to do it in fresh Ubuntu live or even better Tails Portable Operating System or anywhere that you think is free of malware.
Randomly hover, click, scroll the mouse, and type in the text box to generate a random address. The more random your action, the better. Choose paper wallet, and print. If you don't like the default print, then you can just save image as and redesign yourself. If you want a brain wallet instead where you want to generate using your own passphrase, there is a menu.

Hardware Wallet
Let us be realistic, there will be few times in a lifetime that you will often take out your paper wallet and the more often you do that, the more riskier it is. The personal risk of paper wallet is the fragility where it can be damaged or lost. For example, getting rip in an accident and just getting wet a bit may damage the paper. Once it is lost, your coins are unaccessible ideally forever. So, you may rely on electronic storage media to reduce this risk. You can have a hard drive, usb drive, SD card, diskets, or even a whole computer device to store your keys but the important thing is to keep them clean and offline.
Though you can always store your keys or just install the wallets on a USB (universal serial bus) drive, today there are smarter USB devices specifically for cryptocurrency storage called hardware wallet. The first commercial hardware wallet is Ledger Nano but you can get a cheaper one as cheap as $50 called Trezor which I decided to have as my first hardware wallet. While paper wallet is very long term storage, hardware wallet is still practical enough to be used for frequent transaction but still I recommend using hot wallets for high frequency trading.
After turning on your hardware wallet, you can import existing wallets using your seed phrase. If this is your first hardware wallet, I recommend you to make a new one and dedicate as another place to safely hold your coins. Backup and secure the keys and set a lock pin. Then connect the hardware wallet to the computer.
For example using Trezor, install the bridge driver if necessary. Currently, you can manage your wallet by opening a browser with and visit I'm not sure whether you can save page as and open it offline but they provide a manual if you want to install your webserver to access your wallet online or locally at Trezor also plans to integrate with other application, do check, for example it is available for integration in Exodus and Binance DEX

Getting Your First Coin

Now that you have medium to receive your coins whether through custodial wallet, non-custodial wallet, hot wallet, cold wallet, or multiple of them, you are ready to fill them with coins. There are only three ways to get coins which are transacting with someone, mining, and creating one by becoming a developer who invent your own coin. In this section is recommended for new users get coins directly from someone. If you want to get them using your bank account, skip to the next chapter, if you want to mine, skip to later chapter, and if you want to become a developer skip to the next book. Finally the last message in this section is to get yourself some cryptocurrency in order to participate in the ecosystem because without them, your options are limited. Start with something small or more accurately, an amount you are willing to lose or an amount you are comfortable with because if you go in big out of greed expecting to get rich quick, your mentality may not be able to handle it because the market is very volatile where even if in the future the price will sky rocket but it may drop more than half first before that happens.

Coin ATMs
Getting coins from coin automated teller machines (ATM)s in popular areas is my first recommendation because there is no way that these machines escape the eyes of local regulators where you can almost guarantee their safety and security. Go to the search engine and type for example "crypto atm", "bitcoin atm", etc. I found a website called where you can check whether there are crypto ATMS near you. Bring some cash though I'm not sure whether you can use your bank card or not, and bring your public or receiving coin address. If this is your first time in cryptocurrency, do not forget that there are more coins other than Bitcoin and make sure you use the correct public address.

Buy From Someone Trustful
The next best option for starters to get cryptocurrency is to buy from people you trust. People in your circle should be your primary option. Ask your family and friends about cryptocurrency and ask to them to guide you to buy some. With information technologies nowadays, you have more options than contacting them one by one, for example you can post a status or broadcast a message in social media platform. However, only recommended with people you trust because you are new that anyone can easily scam you like selling you fake Bitcoins.
After you are knowledgeable enough like being able to identify fake coins, not sending money to people you cannot meet, and know the correct price in the global market, then I am confident in recommending you find other people. If you can find cryptocurrency community near you, that is great. If not, then there is that can help you lead to people near you who have Bitcoin.

Non-Custodial Credit Card Service
If you have a credit card, then there are convenient online non-custodial service you can use such as Simplex. All you need to do is give them your wallet public or receiving address. However, not all credit cards work for some reason and there are many people who does not have credit card.
