I never heard of this guy until yesterday when I caught this on youtube:
He lost me when he started to get in the weeds on the various crypto's. I have never really examined the whole arena. Though I sure wish I had pulled the trigger back about 10-11 years ago when i was thinking of buying a little bitcoin. Anyway, the guy is super successful and thought you might be interested in watching. Here's his profile: https://en.wikipedia.org/wiki/Mark_W._Yusko
