In my opinion this is one of the best books about the philosophy behind Bitcoin on the German market. In Europe most people see Bitcoin purely as a speculative asset, which it was never supposed to be. It gives access to a whole new universe of opportunities and shows what crypto currencies are actually about: Breaking the banks - and in the process also the governments. Not by fighting them, but by making them obsolete. No wonder it is still a bestseller in the German speaking world. And it is is also available in English on Amazon.
