I might have an idea for your book Ken. The fluctuations of value and how to make this an encouragement rather than a discouraging factor. Someone who throws a hundred dollars in could see it fold 13 times like STEEM was last year in August. This STEEM edition potenitally could offer several times more growth than Bitcoin. Isn't everyone banking on the obvious prediction of STEEM going to the moon. I read one article how STEEM could reach one hundred dollars. OH DARN! Wouldn't that be something awesome! Resteeming for you @kenmelendez!
