Welcome to Bitcoin For Dummies! But just what is bitcoin? How can there be digital money? Is it, like, some kind of Internet money? Is it something you should even be concerned about, or indeed should you shy away from it? In the news, bitcoin coverage tends to be sketchy. You may have read articles about people losing their money, or using bitcoin for illicit purchases on the black market. Or you may have read amazing success stories of people and businesses flourishing by using it.

Fear not, dear readers. This book strips away the mystery and gets down to the facts. It patiently explains exactly what bitcoin is, discusses some of the possibilities this wonderfully disruptive yet inspirational technology holds, and lays out some of the potential benefits for all of us. Bitcoin could change our lives in a similar way that the Internet has done over the last few decades.

In short, this book tells you everything you need to know to get started. So what are you waiting for? Lets, um get started!

Bitcoin For Dummies tells you a bit about the history of this fascinating technology and explores bitcoin as a concept and product. We show you how to open a wallet so that you can safely store your own bitcoins. We even guide you through the process of obtaining some bitcoins. We demonstrate what you may do with those bitcoins and talk about the potential for earning money with them too. We touch upon regulatory and legal frameworks as they currently stand. We detail mining bitcoin and explain how you could become involved in that and why it may not be worth it.

We also prop up the hood and take a good look underneath. We detail how transactions work within the bitcoin environment and delve deep into blockchain technology. We gaze into our crystal ball and speculate on how bitcoin and its blockchain system may develop in the future and how they may change many aspects of our lives. To round things off, we provide you with online resources to keep you up to date and help you become involved with the online community that is actively supporting bitcoin. Come on and join us. We think this will be one heck of a ride!

The only assumption we have about you, our reader, is that you are interested in learning some of the basics about this new form of currency. We hope youll like what you read and will want to create your own wallet, start using bitcoin, and spread the word to friends and colleagues. But our basic assumption is that youve picked up this book because you want to find out more before jumping on board.

We also assume you have some basic experience with computers and the Internet. We figure you already know how to find your way around the Internet and how to take some simple steps to safeguard yourself online and protect your money. We dont expect you to be a tech expert who knows all there is to know about computing.

And thats because you dont need to be an expert to get started with bitcoin.

To help you pick out the information most useful to you, weve used a few graphical icons in the book to highlight key details. Whenever you see the following icons in the page margin, this is what you can expect from that paragraph:

We like to dispense our advice on a warm plate, ready for your consumption. This icon highlights our top tips for getting the best out of bitcoin and often includes insider knowledge to help you to achieve what you want as quickly and efficiently as possible.

When you see this icon on the page, were speaking to you with our deep, velvety public information announcer voice: These are the most salient points to squirrel away in your brain for later use.

This icon warns you of common mistakes or pitfalls that could trip you up when it comes to bitcoin. We know youre going to use your common sense when it comes to money and online transactions, but from time to time we just like to tap you on the shoulder and say, Pay attention and be careful. This icon is that tapping finger.

Online finances, the Internet, and bitcoin itself all have many weird and wonderfully specific ways of describing things, doing things, and generally flummoxing the unwise. Sometimes having a bit of slightly esoteric background knowledge helps, even if its not directly related to getting the best from your bitcoin. This icon flags the parts you can safely skim over and not lose out by doing so.
