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.
Yeah, that's what I think he's doing. He's trying to influence the community and to follow his trades. But it seems that isn't working for him. He's still profit I think and these losses, he can avail all of them.
He also messaged CZ and the reason IMO is for these dexes not to show or track their trades by someone. And there's already a respond from CZ and it's about 'dark pool'.
Let's see who's going to listen to his proposal or if he's doing already something about it.
