So there is no reason to think this would be different. And that is ignoring the fact that FTX has (had?) a sub-venue called "FTX US" specifically for US persons, which has also failed.<p>Also, there are a whole bunch of crimes (including wire fraud) where the definition of the crime makes intent so low, it is no barrier to prosecution. This is why you often see major frauds charged as more minor crimes: Fraud requires intent, Wire Fraud just requires a lie, a phone line and some profit.
