“Digital Gold” is a history of Bitcoin from its creation until early 2014. Popper does a good job of covering how the early cryptocurrency movement was based in naive nerd libertarianism (well, that’s my takeaway, anyway), the rise and fall of Mt. Gox, and the hunt for “Dread Pirate Roberts“.
I wouldn’t characterize Popper as a Bitcoin skeptic, but he’s certainly not a Bitcoin cheerleader. I do wonder how anyone could put real money into Bitcoin (except as a speculative gamble) after reading this book.
