Introduction

The foundation of cryptocurrencies such as Bitcoin lies in a new technology called the blockchain; it’s the infrastructure that cryptocurrencies are built on. Blockchain is a disruptive technology that many argue is bigger than the advent of the Internet. The applications of blockchain don’t end with cryptocurrencies, though, just like the applications of the Internet don’t end with email. If you want to find out what blockchains are, the basics of how to use them, which cryptocurrencies are lucrative investments, and what hardware is needed for cryptocurrency mining, this is the book for you.

About This Book

In this book, you find helpful advice for navigating the blockchain world and cryptocurrencies that run them — from the ins and outs of wallets, exchanges, Bitcoin, and Ethereum to investing in cryptocurrencies and even mining your own.

You don’t have to read the book cover to cover. Just flip to the subject that you’re interested in.

As you dip into and out of this book, feel free to skip the sidebars (shaded boxes) and the paragraphs marked with the Technical Stuff icon. They contain interesting but nonessential information.

Within this book, you may note that some web addresses break across two lines of text. If you’re reading this book in print and want to visit one of these web pages, simply key in the web address exactly as it’s noted in the text, pretending as though the line break doesn’t exist. If you’re reading this as an e-book, you’ve got it easy — just click the web address to be taken directly to the webpage.

Some of the web addresses are affiliate links, meaning that if you click them and start using a company’s services through that specific web address, the author may earn an affiliate payment for making the introduction.

Foolish Assumptions

We didn’t want to make too many assumptions about you and your experience with cryptocurrency, blockchains, mining, and legal matters, but we do assume the following:

You have a computer, a smartphone, and access to the Internet.

You know the basics of using your computer and the Internet, and how to download and install programs.

You know how to navigate through menus within programs, how to find files on your computer, and how to create folders.

You’re new to blockchain and you aren’t a skilled programmer. (Of course, if you are a skilled programmer, you can still get a lot out of this book — you just may be able to breeze past some of the step-by-step guidelines.)

You may have heard of, or even purchased, some cryptocurrencies (like Bitcoin or Ether, for example), but you don’t really know how they work.

Although you may have invested in other markets like the stock market before, you aren’t necessarily familiar with the terminology and the technical aspects of trading and investing in cryptocurrencies.

You are unfamiliar with cryptocurrency mining but are interested to know more and determine whether it’s something you want to undertake.

Note: If you don’t have high-speed access to the Internet, you may want to get it before diving into this book. You need high-speed access to be able to work with many of the valuable online tools that we recommend.

Icons Used in This Book

Throughout the margins of this book are icons drawing your attention to certain bits of information. Here’s what those icons mean.

The Tip icon marks tips and shortcuts that you can use to make your life with cryptocurrency easier.

The Remember icon marks the information that’s especially important to know — the stuff you’ll want to commit to memory.

When you see this icon, you know the information is of a highly technical nature. You can skip over these icons without missing the main point of the topic at hand.

Watch out when you see this icon! It marks critical information that may save you headaches — or tokens.

Beyond the Book

In addition to the material in the print or e-book you’re reading right now, this product also comes with some access-anywhere content on the web. Check out the free Cheat Sheet for more on the topics covered in the book.

Where to Go From Here

The Dummies series tells you what you need to know and how to do the things you need to do to get the results you want. Readers don’t have to read the entire book to learn about a topic. Like all good reference tools, this book is designed to be read when needed and it’s divided into several parts.

If you’re interested in investing, for example, you can head to Book 5 to learn about risk management, strategy development, and the whole industry in general. Book 1 provides an overview of the world of cryptocurrencies, and Book 2 is your gateway to the blockchain technology.

Book 3 takes a deep dive into Bitcoin, which is the oldest cryptocurrency and probably the most well-known. Book 4 lays the foundation of Ethereum and teaches you, in clear language, how to design and write your own software for the Ethereum blockchain environment.

If you want to delve into cryptocurrency mining, check out Book 6, which can help you decide if and how you’re going to begin mining, including which is the right cryptocurrency for you to mine.

What Is a Cryptocurrency?

IN THIS CHAPTER

Looking at the what, why, and how of the advent of cryptocurrencies

Getting an overview of your first steps before starting your crypto journey

So you’ve picked up this book, and your first question is probably this: “What the heck is a cryptocurrency, anyway?” Simply stated, a cryptocurrency is a new form of digital money. You can transfer your traditional, non-cryptocurrency money like the U.S. dollar digitally, but that’s not quite the same as how cryptocurrencies work. When cryptocurrencies become mainstream, you may be able to use them to pay for stuff electronically, just like you do with traditional currencies.

However, what sets cryptocurrencies apart is the technology behind them. You may say, “Who cares about the technology behind my money? I only care about how much of it there is in my wallet!” The issue is that the world’s current money systems have a bunch of problems. Here are some examples:

Payment systems such as credit cards and wire transfers are outdated.

In most cases, a bunch of middlemen like banks and brokers take a cut in the process, making transactions expensive and slow.

Financial inequality is growing around the globe.

Around three billion unbanked or underbanked people can’t access financial services. That’s approximately half the population on the planet!

Cryptocurrencies aim to solve some of these problems, if not more. This chapter introduces you to crypto fundamentals.

Beginning with the Basics of Cryptocurrencies

You know how your everyday, government-based currency is reserved in banks? And that you need an ATM or a connection to a bank to get more of it or transfer it to other people? Well, with cryptocurrencies, you may be able to get rid of banks and other centralized middlemen altogether. That’s because cryptocurrencies rely on a technology called blockchain, which is decentralized (meaning no single entity is in charge of it). Instead, every computer in the network confirms the transactions. Flip to Book 2 to find out more about the blockchain technology that enables cool things like cryptocurrencies.

The following sections cover the basics of cryptocurrencies: their background, benefits, and more.

The definition of money

Before getting into the nitty-gritty of cryptocurrencies, you need to understand the definition of money itself. The philosophy behind money is a bit like the whole “which came first: the chicken or the egg?” thing. In order for money to be valuable, it must have a number of characteristics, such as the following:

Enough people must have it.

Merchants must accept it as a form of payment.

Society must trust that it’s valuable and that it will remain valuable in the future.

Of course, in the old days, when you traded your chicken for shoes, the values of the exchanged materials were inherent to their nature. But when coins, cash, and credit cards came into play, the definition of money and, more importantly, the trust model of money changed.

Another key change in money has been its ease of transaction. The hassle of carrying a ton of gold bars from one country to another was one of the main reasons cash was invented. Then, when people got even lazier, credit cards were invented. But credit cards carry the money that your government controls. As the world becomes more interconnected and more concerned about authorities who may or may not have people’s best interests in mind, cryptocurrencies may offer a valuable alternative.

Here’s a fun fact: Your normal, government-backed currency, such as the U.S. dollar, must go by its fancy name, fiat currency, now that cryptocurrencies are around. Fiat is described as a legal tender like coins and banknotes that have value only because the government says so. Get the scoop on fiat currencies in Book 5, Chapter 9.

Some cryptocurrency history

The first ever cryptocurrency was (drumroll please) Bitcoin! You probably have heard of Bitcoin more than any other thing in the crypto industry. Bitcoin was the first product of the first blockchain developed by some anonymous entity who went by the name Satoshi Nakamoto. Satoshi released the idea of Bitcoin in 2008 and described it as a “purely peer-to-peer version” of electronic money.

Bitcoin was the first established cryptocurrency, but many attempts at creating digital currencies occurred years before Bitcoin was formally introduced.

Cryptocurrencies like Bitcoin are created through a process called mining. Very different than mining ore, mining cryptocurrencies involves powerful computers solving complicated problems. Book 6 covers mining, but flip to Book 6, Chapter 1 for an introduction to cryptocurrency mining.

Bitcoin remained the only cryptocurrency until 2011. Then Bitcoin enthusiasts started noticing flaws in it, so they decided to create alternative coins, also known as altcoins, to improve Bitcoin’s design for things like speed, security, anonymity, and more. Among the first altcoins was Litecoin, which aimed to become the silver to Bitcoin’s gold. But at the time of this writing, over 5,000 cryptocurrencies are available, and the number is expected to increase in the future. Check out Chapter 4 of this minibook for just a sampling of cryptocurrencies that are available now.

Key crypto benefits

Still not convinced that cryptocurrencies (or any other sort of decentralized money) are a better solution than traditional government-based money? Here are a number of solutions that cryptocurrencies may be able to provide through their decentralized nature:

Reducing corruption:

With great power comes great responsibility. But when you give a ton of power to only one person or entity, the chances of their abusing that power increase. The 19th-century British politician Lord Acton said it best: “Power tends to corrupt, and absolute power corrupts absolutely.” Cryptocurrencies aim to resolve the issue of absolute power by distributing power among many people or, better yet, among all the members of the network. That’s the key idea behind blockchain technology, anyway (see

Book 2

).

Eliminating extreme money printing: Governments have central banks, and central banks have the ability to simply print money when they’re faced with a serious economic problem. This process is also called quantitative easing. By printing more money, a government may be able to bail out debt or devalue its currency. However, this approach is like putting a bandage on a broken leg. Not only does it rarely solve the problem, but the negative side effects can also sometimes surpass the original issue.

For example, when a country like Iran or Venezuela prints too much money, the value of its currency drops so much that inflation skyrockets and people can’t even afford to buy everyday goods and services. Their cash becomes barely as valuable as rolls of toilet paper. Most cryptocurrencies have a limited, set amount of coins available. When all those coins are in circulation, a central entity or the company behind the blockchain has no easy way to simply create more coins or add on to its supply.

Giving people charge of their own money:

With traditional cash, you’re basically giving away all your control to central banks and the government. If you trust your government, that’s great, but keep in mind that at any point, your government is able to simply freeze your bank account and deny you access to your funds. For example, in the United States, if you don’t have a legal will and own a business, the government has the right to all your assets if you pass away. Some governments can even simply abolish bank notes the way India did in 2016. With cryptocurrencies, you and only you can access your funds. (Unless someone steals them from you, that is. To find out how to secure your crypto assets, flip to

Chapter 3

of this minibook.)

Cutting out the middleman:

With traditional money, every time you make a transfer, a middleman like your bank or a digital payment service takes a cut. With cryptocurrencies, all the network members in the blockchain are that middleman; their compensation is formulated differently from that of fiat money middlemen and therefore is minimal in comparison. Check out

Chapter 2

of this minibook for more on how cryptocurrencies work.

Serving the unbanked:

A vast portion of the world’s citizens has no access or limited access to payment systems like banks. Cryptocurrencies aim to resolve this issue by spreading digital commerce around the globe so that anyone with a mobile phone can start making payments. And yes, more people have access to mobile phones than to banks. In fact, more people have mobile phones than have toilets, but at this point the blockchain technology may not be able to resolve the latter issue. (Flip to Book 5,

Chapter 1

for more on the social good that can come from cryptocurrencies and blockchain technology.)

Common crypto and blockchain myths

During the 2017 Bitcoin hype, a lot of misconceptions about the whole industry started to circulate. These myths may have played a role in the cryptocurrency crash that followed the surge. The important thing to remember is that both the blockchain technology and its byproduct, the cryptocurrency market, are still in their infancy, and things are rapidly changing. So let’s get some of the most common misunderstandings out of the way:

Cryptocurrencies are good only for criminals.

Some cryptocurrencies boast anonymity as one of their key features. That means your identity isn’t revealed when you’re making transactions. Other cryptocurrencies are based on a decentralized blockchain, meaning a central government isn’t the sole power behind them. These features do make such cryptocurrencies attractive for criminals; however, law-abiding citizens in corrupt countries can also benefit from them. For example, if you don’t trust your local bank or country because of corruption and political instability, the best way to store your money may be through blockchain and cryptocurrency assets.

You can make anonymous transactions using all cryptocurrencies.

For some reason, many people equate Bitcoin with anonymity. But Bitcoin, along with many other cryptocurrencies, doesn’t incorporate anonymity at all. All transactions made using such cryptocurrencies are made on public blockchain. Some cryptocurrencies, such as Monero, do prioritize privacy, meaning no outsider can find the source, amount, or destination of transactions. However, most other cryptocurrencies, including Bitcoin, don’t operate that way.

The only application of blockchain is Bitcoin.

This idea couldn’t be further from the truth. Bitcoin and other cryptocurrencies are a tiny byproduct of the blockchain revolution. Many believe Satoshi created Bitcoin simply to provide an example of how the blockchain technology can work. Almost every industry and business in the world can use the blockchain technology in its specific field.

All blockchain activity is private.

Many people falsely believe that the blockchain technology isn’t open to the public and is accessible only to its network of common users. Although some companies create their own private blockchains to be used only among employees and business partners, the majority of the blockchains behind famous cryptocurrencies such as Bitcoin are accessible by the public. Literally anyone with a computer can access the transactions in real time. For example, you can view the real-time Bitcoin transactions at

Risks

Just like anything else in life, cryptocurrencies come with their own risks. Whether you trade cryptos, invest in them, or simply hold on to them for the future, you must assess and understand the risks beforehand. Some of the most talked-about cryptocurrency risks include their volatility and lack of regulation. Volatility got especially out of hand in 2017, when the price of most major cryptocurrencies, including Bitcoin, skyrocketed above 1,000 percent and then came crashing down. However, as the cryptocurrency hype has calmed down, the price fluctuations have become more predictable and followed similar patterns to stocks and other financial assets.

Regulations are another major topic in the industry. The funny thing is that both lack of regulation and exposure to regulations can turn into risk events for cryptocurrency investors. See Book 5, Chapter 2 to explore these and other types of risks, as well as methods of managing them.

Gearing Up to Make Transactions

Cryptocurrencies are here to make transactions easier and faster. But before you take advantage of these benefits, you must gear up with crypto gadgets, discover where you can get your hands on different cryptocurrencies, and get to know the cryptocurrency community. Some of the essentials include cryptocurrency wallets and exchanges.

Wallets

Some cryptocurrency wallets, which hold your purchased cryptos, are similar to digital payment services like Apple Pay and PayPal. But generally, they’re different from traditional wallets and come in different formats and levels of security.

You can’t get involved in the cryptocurrency market without a crypto wallet. Get the most secure type of wallet, such as hardware or paper wallets, instead of using the convenient online ones. Flip to Chapter 3 of this minibook to explore how these wallets work and how you can get them.

Exchanges

After you get yourself a crypto wallet (see the preceding section), you’re ready to go crypto shopping, and one of the best destinations is a cryptocurrency exchange. These online web services are where you can transfer your traditional money to buy cryptocurrencies, exchange different types of cryptocurrencies, or even store your cryptocurrencies.

Storing your cryptocurrencies on an exchange is considered high risk because many such exchanges have been exposed to hacking attacks and scams in the past. When you’re done with your transactions, your best bet is to move your new digital assets to your personal, secure wallet.

Exchanges come in different shapes and forms. Some are like traditional stock exchanges and act as a middleman — something crypto enthusiasts believe is a slap in the face of the cryptocurrency market, which is trying to remove a centralized middleman. Others are decentralized and provide a service where buyers and sellers come together and transact in a peer-to-peer manner, but these exchanges come with their own sets of problems, like the risk of locking yourself out. A third type of crypto exchange is called hybrid, and it merges the benefits of the other two types to create a better, more secure experience for users. Flip to Book 5, Chapter 3 to review the pros and cons of all these types of exchanges and get to know other places where you can go cryptocurrency shopping.

Communities

Getting to know the crypto community can be the next step as you’re finding your way in the market. The web has plenty of chat rooms and support groups to give you a sense of the market and what people are talking about. Here are some ways to get involved:

Crypto-specific Telegram groups.

Many cryptocurrencies have their very own channels on the Telegram app. To join them, you first need to download the Telegram app on your smartphone or computer; it’s available for iOS and Android.

Crypto chat rooms on BitcoinTalk or Reddit:

BitcoinTalk (

https://bitcointalk.org/

) and Reddit (

www.reddit.com/

) have some of the oldest crypto chat rooms around. You can view some topics without signing up, but if you want to get involved, you need to log in. (Of course, Reddit isn’t exclusive to cryptos, but you can search for a variety of cryptocurrency topics.)

TradingView chat room:

One of the best trading platforms out there, TradingView (

www.tradingview.com/

) also has a social service where traders and investors of all sorts come together and share their thoughts, questions, and ideas.

Invest Diva’s Premium Investing Group:

If you’re looking for a less crowded and more investment/trading-focused place to get support, you can join Kiana’s investment group (and chat directly with her as a perk) at

https://learn.investdiva.com/join-group

.

On the flip side, many scammers also target these kinds of platforms to advertise and lure members into trouble. Keep your wits about you.

Making a Plan Before You Jump In

If you’re interested in cryptocurrency investing, you may just want to buy some cryptocurrencies and save them for their potential growth in the future. Or you may want to become more of an active investor and buy or sell cryptocurrencies more regularly to maximize profit and revenue. As discussed in Book 5, Chapter 4, you can select cryptocurrencies based on factors like category, popularity, ideology, the management behind the blockchain, and its economic model.

Even if your transaction is a one-time event and you don’t want to hear anything about your crypto assets for the next ten years, you still must gain the knowledge necessary to make the following decisions:
