I highly recommend Nathaniel Popper’s book Digital Gold: The Untold Story of Bitcoin to any geeks.
It’s a fascinating story of how Bitcoin came to be and follows the paths of the different persons around the cryptocurrency from the very beginning of it. The book covers the story, specifically, and is not a technical guide to blockchain or whatever. It starts from the Nakamoto’s paper and how he tried to get people interested in it and goes through the early years of development, the people behind it, the firms spun up for it, legislative reception, and also the whole Silk Road case with Dread Pirate Roberts and so on. Also, it covers lots of different products multiple firms made for the Bitcoin ecosystem and how they were received, what problems they had, and where they are now (if they still are, that is).
It’s a very nice read and gives you thorough understanding of the whole thing. I had had a small itch for understanding Bitcoin better but never took the time to truly study the inner-workings of it. This book got me very excited about it and gave a very good introduction to it via the history. Now I’ve got my hands on Blockchain Revolution, which is not a story but a true technical book that covers what’s next in the blockchain world. If you’re not interested in Bitcoin’s history, I recommend this one.
