Compared to bank accounts, real estate, and offshore corporations, it is certainly easier to hide your crypto (or rather, hide the fact that it's your crypto) if you know what you're doing. Heck, even the word "crypto" means "hidden".

Do Kwon might not be any good at sneaking though airports, but he certainly knows his way around the crypto scene. He has had plenty of time to launder his coins. In fact, he's probably had more time to plan and execute an exit scheme than any of the other crooks who got busted lately. So I wouldn't underestimate how well he has hidden his embezzled billions.
