He's known to be a gambler.
I see that some have questioned the source of the OP, I'll post a couple of links that reaffirm what you say:
Sam Bankman-Fried Caught in Losing $100M at Online CasinosThe former co-CEO of Sam Bankman-Fried's Alameda crypto trading firm was a risk-loving, poker-playing gamblerSo it does appear that at least some of the depositors' funds were lost by gambling in the casino.
I don't understand this. The FTX customers are the losers here. Sam didn't lost anything and he was flying on business class two days ago after being granted bail. Now it is clear that he will not spend even one day in jail, despite stealing almost $10 billion from the FTX clients. It ended in a way which is extremely beneficial for him. The idiots who trusted him and kept their money in FTX accounts are the ones who got royally screwed. His bail was set at $250 million. For him it wasn't very hard to set up the bail from the stolen assets.
Don't talk rubbish. He's not finished to begin with, bail doesn't mean he won't go to jail. He will go to jail and he won't be able to spend the money there.
