Was it mentioned if the hacker/white hat was going to return the BTC that they withdrew?
If they don't return that BTC, Poloniex would be out of pocket in a huge way.
I hope we can pull together an adequate bounty for the white hat such that they will return all BTC.
He said he would, but I haven't heard from him since he explained the vulnerability. My guess is he is waiting on the block chain rebuild to see where he stands with XCP.
If all the XCP gets returned to the Poloniex account, then the dump will stand, and he can keep the BTC. If not... then let's hope he returns it, and I'm going to have to roll back some trades.
a) It doesn't make sense to forcefully take the users XCP, and sell it at 0.002 , when they never intended to sell it at that price.
b) The 35k XCP also includes XCP from users who purchased them on previous day and are holding them at exchanges.
