We wrote this book to help others to discover the true potential of Bitcoin — as a simple, transparent, and borderless currency. Our goal is to explain the technology behind it in a way that's easy to understand, without overwhelming technical jargon. At the same time, we share our personal journey: how Bitcoin enabled us to live a free, independent life. With this book, we hope not only to educate, but also to contribute to the global adoption of Bitcoin and move toward a fairer, decentralized financial system.
