after reading the forum a bit, a roll back really is the only thing he can do(right or wrong being irrelevant),
though it's funny watching all the guys that got there 0.10 orders filled going crazy calling the roll back bullshit
saying its the only thing he can do is based on the assumption that mtgox doesn't personally own 500k btc or the cash equivalent to pay the 500k owner back, just opening the exchange with no roll back and letting the low orders stand would mean he is just ignoring the guy with the lost 500k btc and that would be worse than the fecking hack, "oh you lost millions on my exchange? tough shit!, stop e-mailing me everyday about it ffs... want some cheese with that whine?"
although even if he did have the 8 million $
he is still looking at the choices of
1: let all orders stand and screw the 500k customer
2: pay the millions back personally and let all orders stand (haha)
3: roll back and pay the few thousand himself
4: close exchange and flee with all the cash
is this a fair assessment?
