CZ will not be able to directly hold any responsibilitiy at Binance management yet
I am not so sure about that. Maybe he can now that he has been pardoned by Mr President. There has been no news about that after his pardon, though a lot of people even believe that he was and still controls binance, just behind the scenes. So maybe there is no meed for him to take centre stage again.
However, CZ also has shown that he is influential when he convinced the people behind the president to pardon him. This very much shows that he is a person similar to Bill Gates or other great CEOs.
Maybe that is not so hard right now, especially if you have something to offer in return.
