Some people got rich with Ponzi’s original Ponzi scheme, so from a certain narrow point of view that was… useful?… as well.
The only hope for a happy ending with this guy is that he chooses to cash out of bitcoin at some time when everyone else isn’t doing it. If he got out now, he might end up with more real-world money than he put in.
But if he’s the kind of person to dump his life savings into crypto, he’s probably also the kind of person to hang onto it past the point where it makes sense. Or to use his BTC to “buy the dip” and stock up on Terra now that it’s “cheap”, or something like that.
If I read that he sold his bitcoins for US$6million (and paid Dutch taxes on that!) and bought a nice house or something, then good for him. But until then, deciding whether he’s winning or losing is extremely premature. When you see a guy with glazed eyes dripping with sweat at a roulette table, you don’t assume he’s set up for life even if he has a big pile of chips in front of him.
