He's either a Mega Dumb Ass or he's a Mega Genius. Depends on what was taken from him was all of his assets, or if he was clever enough to have a lot more hidden. Only he knows the answer to this.
Whatever he has/had, it obviously wasn't set up good enough. That's the thing about proper asset protection, if you do it right, they won't get it. And if they do, they can't keep it. If it's done really well, they won't even know about it.
Just having bank accounts in other people's name and a few corps is not enough. It's all about how it's structured.
For the kind of money they were making, they should have had a more secure structure in place, and lots of it hidden, which they may have done. What is on the news just may be a small percent of it all, we'll never know. It's possible what they took is what he was willing to lose, and somewhere else he's sitting on something much larger.

Tirak, I'm going to open a bank account and put 80 million in it, OK?
Would have lasted about 2 hours, max.
