I still haven't gotten around to reading that book that you suggested. My wife was going to buy it for me and then saw the price and decided to wait a little. I am happy to see you posting. It has been a while and I was getting worried. I sent you a small transfer today so I could write something in the memo to check up on you. The bitcointalk forum is a good place to start. I learned a lot just by following Reddit and reading stuff on there though you can't always know if what you are reading is legit or not. Telegram is a good place to learn about new things and ask questions depending on the coin you are specifically interested in. Medium is also a really good place. There are some really fantastic articles on there.
