Do Kwon is not yet convicted, but i think there might be some skeletons in is his cardboard, he might have some wrong doing, even if he claimed not quity, as an expert, there are people who are smarter and more experienced on the cryptocurrency technology than him.
He has to answer and clear himself from all the charges that is currently before him, and if unable to defend himself of the alligations, then he should be ready for jail.
