I got altcoins there as well. Wondering whats going to happen. The worst would be if they just left with the coins. but coins will be unusable, I mean you can trace down each transaction untill the origin, so actually it is bad for illegal transactions unless you never pay out your btc or verrify your identity somewhere.
I hope they won't run since if the CEO was involved in laundering money from Mt. Gox, he didn't get away with it, I think they will feel that they may not get away with it either.
Let's wait.
