Could be. Thinking about it it is notoriously watched money if it moved to any exchange it would be seized.
By whom?
If it were moved to an online exchange outside of US jurisdiction exactly why would it be seized?
If
Pauldemort or anyone else moved it in large chunks they might need AML/KYC thus will avoid it but there must be many ways for the person/people in control of those coins to grab the stolen money and have fun just like The Donald did when he grabbed them pussycats

Good point but any of the ones that can cash that kind of coin out are all in communication. There are side channels between most of them (Skype/IRC) to talk that kind of stuff even exchanges you would not think communicate do (BTC-E is probably one of the better ones for communication like that FYI). End result is you have to get that cash out in your name so I doubt they ever will.
