I mean there are also other stories; an acquaintance (he invested in my business with cash in 2018) got out end 2017 with around 60m$ in cash; he was a waiter making minimum wage who borrowed 50k$ from his family who remortgaged their house (not rich people but at least house owners) in 2014 and gambled his families future and accidentally (he was a real believer, but the 'business scams' around blockchain made him a non-believer) gambled right. It's a weird casino.
Maybe it is my circle (but I read it on reddit all the time the past 10 years though) but the financially illiterate seem far more likely to 'invest' with borrowed money, do not diversify and put 'everything on red'/all-in kind of thing and then don't know what to do when that goes wrong (lie to their spouses and kids about it). An senior sales guy of my (then) company invested ALL his money and borrowed more (totaling many millions) in a Dutch web stock (worldonline) and lost everything; his wife, son, house, cars; basically life.
