All of my reading has been in the various forums and whitepapers. I understand that The Coming Age of Cryptocurrency by Paul Vigna is a good book that has a lot to say about blockchains and their potential for transformation. It's on my reading list, but I haven't gotten to it yet.
Agreed on that referral. Paul (and his co-Author Mike Casey who is an Agentic Group Adviser) take you through a very comprehensive primer on Bitcoin 101, the players and ecosystem, and more importantly the profound impact it could have on society. You might also want to read "The Bitcoin Big Bang: How Alternative Currencies Are About to Change the World" by CNBC's Brian Kelly.
