Thanks so much for recommending this book I will definately pick it up. Because I am a olden golden oldie I appreciate the fact that it is for beginnings as I find a lot of the info about cryto is far to advanced. My son introduced me to Steem and investing in crypto in the summer and is really good at answer any questions but a book would probably be able to teach me the basics and can be my go to book. You are always so helpful....appreciate it.
