I heard about JB here at steemit and have looked into some of his older as well as newer YT vids and his TDV blogs, and have checked out what others say about him. After digging a little I discovered that he was involved in a very dirty real estate scam in Chile that cost a lot of people a lot of money (in some instances a big chunk of their life-savings). I've also learned that he used to sell foreign-passports to people so that they could avoid paying taxes, but that he no longer, apparently, offers these services. Why? Well, from what I can gather he was also involved in fraudulent actions in this area as well. From reading the YT comments under his vids, I've seen a fair number of people claim that his investment advice, contrary to his bragging about how he recommended Bitcoin and a few winning options, hasn't turned out very well for his subscribers. Jeff is a very well-spoken and charismatic man, and says all of the right things, but libertarians should be a little wary of him, IMO.
