CZ gave it to him at the request of the SEC regulators when Binance was in trouble. It is difficult to prove and this is my opinion, but this situation is not accidental.
CZ is a player, and he is involved in all this from the beginning.
I already posted something about that:
And SBF is crazy! He basically put almost everything in his FTT token, making his projects vulnerable. Of course, the question is how much did CZ contribute to the downfall of FTX itself, I'm sure he had information about what was going on, that tweet that he is selling his holdings in the FTT token... and later his "changing mind" about whether to take over FTX or not seems like playing cat and mouse when I think about it now.
Well, it's crypto in the end! Online wild west!
