IANAL. What's his defense?
There's no need to talk about any defence strategy if there are no specific accusations. And by specific I mean specific: what is the accusation? (Just to be clear, I am not on his side. I'm just pedantic.)
If his Twitter deception is anything to go by, he liked lied to investors about pilfering customer funds to bail out failed Alameda Research. Forget about lying, it's illegal to even withhold pertinent information when pitching to US investors.
The Bahamas is no safe haven. They will extradite. After all, his investors are in the US and those transactions are covered by SEC rules. Given the scale of the fraud here, this is serious jail time.
He could be saved by his political bribes, though, considering he's greased the palms of the current administration (#2 Democrat donator in the recent cycle) ;)
