I have never been the least bit curious about the whole crypto currency thing, but I still found this documentary to be interesting and appreciated learning the basics behind all of it in the course of this film. Of course, once we went off the gold standard, U.S. currency was similar to crypto cash in that in order for it to be worth what it claims, people have to believe in its value. But this is more of a mystery, the history of young Mr. Cotten’s career. Entrepreneur or con man? Natural death, foul play or faked death? Considering how secretive Cotten’s life and businesses were, this documentary does a credible job uncovering and locating evidence to shed light on what happened. I won’t cover that ground here. Suffice to say that if you have interest in crypto currency or conspiracy theories about the deaths of wealthy people, s=you should enjoy this tale.
