You might have heard that "these things are coming" and "will take over the world." No matter if you have or haven't, "they" are right-these things are coming. And "these things" will play just as important a role as the internet has for the past 20 years. You know who "won" with the internet? The people who started preparing for it at the beginning, using it personally or for their business before others did. With this new technology called blockchain, a similar window of opportunity has started to open. If you have no clue what a blockchain, a cryptocurrency, or Bitcoin is, don't worry-most of the population doesn't. One of the main challenges for anyone trying to get familiar with these topics is the question of "Where should I start?" This is exactly what prompted me to write this book. In the simplest way possible, I will explain all the aforementioned points so even a 10-year-old could understand them. At the same time, I will reference the details on a technical level to give you both the large scale and the detailed picture. Explaining something to a 10-year-old is in no way a commentary on anyone's intelligence. I'm just following Albert Einstein's advice: "If you can't explain it simply, you don't understand it well enough."
