The book is a journey through my experiences with Bitcoin and cryptocurrencies since 2011, from the ancient economy definition of "exchange energy" to the daily practice of using it as a currency and conserving it as a store of value. It describes how I started and how I still use it, since it changed the economic world evolution and progress, and not only that. Bitcoin is not just a currency, but a protocol. Imagine a coin that occasionally transforms into what you need most, it activates if the conditions that you have included in the program are met. Satoshi Nakamoto invented distributed consensus, a decentralized currency that does not have a single owner. You have the "keys to your money", a sentence I often say. You can develop a passion for reading this book lightly. You will find practical advice derived from experiences I have really made with "my Bitcoin" over the years: how do I buy it, how can I mine it, sell it or receive it, how do I protect and store it, monitor it, learn to use ATMs, and what ICOs are form 2020 the DeFi. In short, a journey that has already taken place that helps you avoid all the mistakes I have made as a pioneer of this new economic era.
