SBF decided to testify against CZ to try to save his own ass, giving justice dept and sec something to fine CZ with. Govt collects a big crypto fine, fine makes the big losers in FTX whole, problem solved. CZ should have just bought FTX and closed the deal and made people whole, woulda saved himself some drama.
CZ is the one who pretty much orchestrated the FTX collapse. Chickens, home to roost, etc.
"It's only when the tide goes out that you see who's swimming naked". The tide was going out even without CZ's actions. And FTX was swimming naked to the bone.
