He's not a legend but only became one because he's got a huge fund to gamble with through his leverage trades.
He is using a massive leverage and which is not good. Probably he thought bitcoin is like other coins that they can manipulate easily but he leaned a lesson as his trading fund that he used to open bitcoin long position got liquidated. But he can not be called a scammer.
Exactly he can’t be called a scammer because he has not stolen money from anyone in pretense of putting them through how to trade. He made his money through memecoins that he stakes a high amount of money on them. Normally, trading memecoins are like gamble because they can rug you but at the same time when you get them right, you’ll earn big from them and that’s the luck he has gotten himself into to win this big.
He has earned this big name for himself through consistent trading of this altcoins to make big shots, we shouldn’t see him as a scammer but more or a less a big risk take which anyone can also be and get the luck to win it big. People become popular through different ways but make sure you earn it the right way and everyone will like the hang with you. CZ answering his DM shows that he’s a big shot in the crypto space although I don’t really know him.
