I ended up watching it last night. It was quite good even having know the story already. He admitted that it was greed that fuelled his bad decisions so at least he is aware of that. At one point he said that no one wants to get rich slowly, which I think is true in a lot of cases for a lot of people, but it's a mentality that is unrealistic for the majority and one which makes people take bigger and bigger risks. Investing ends up being g more akin to just plain gambling. Ultimately he risked 400 thousand dollars of his entire life savings to save about 6 thousand dollars... max...
That decision doesn't really make any sense.
Still sucks that he got burnt like that though. Unfortunately I'm sure there are hundreds of similar crypto and stock stories out there.
