It is incorrect to blame CZ over this, social media is full of useless and emotional rants without facts behind them, it should be obvious that CZ backed out of his offer to buy FTX at first because he could, as he was not legally bound to buy FTX, but even more importantly he only needed to take a look at their books for a few hours to know there was no way to save the situation.
And he was right, FTX declared bankruptcy just a few days later, which shows he was right about the reading he had about the desperate situation FTX was.
I agree, i started by blaming him, but that was before i knew how bad things were.
But i am pretty sure that cz will be extra careful with wording next time he wants to hint that there something shady going on. Reporting these issues to officials rather then with twitter. I am pretty sure he would get tether short time liquidity crunch mode with just one tweet as not everything in there are going to be instantly liquid.
