Bitcoin for the Befuddled, as this book is called, was released back in November of 2014, and some of the information might be slightly outdated. However, this book is mostly focusing on the core principles of Bitcoin, the history of cryptocurrency, and includes details on the blockchain as well. It is good to see such a book as part of the Humble Book Bundle for sure. Keeping in mind how the regular ebook would cost US$19.95, paying the full price for this book bundle will still save interested users money, and they will get a lot of other good books as well.
