Yeah, his name comes up in the Folding Ideas video. Don't remember his name though, but if I remember correctly, he was a stock trainer who realised that large investors had large bets on game stop stock going down, and if it instead went up there was a lot of money to be made by betting on it going up. So he made such bets, spread the word, stock went up, he got rich and exited stage left without getting prosecuted for market manipulation.

But by then the whole memestock thing was of to the races.
