How much does the jackass that stole all of this have in possession in theory? From what i've read it's 11k BTC. That's $222,200,000 at current rates. Just having to launder all of that gives me an headache. He's going to spend more time trying to not screw up mixing utxo's and trying not to send a transaction that uses one that identifies him in some fiat gateway and then trying to justify where all this money came from than actually enjoying the money. If we were in the 90's I would say he would easily do it in some remote tax haven island but nowadays it's becoming increasingly difficult, so he's going to end up in one of the few areas that escape the up and coming supranational rulings on money laundering. By the time someone increases it's networth a lot it will be obvious, unless he just cashes out small amounts to not raise alarms but then again you are insanely rich but you cannot enjoy the money.

Of course, recovering the money is another story. I have myself some funds lost in there and I have some emails and screenshots, but for peace of mind I have considered the funds lost years ago.
