Yikes, that really sucks. I wonder if they are going to roll back the blockchain. I understand why people don't like that, but maybe it would deter hackers. If the hackers knew that every time there was a hack, the blockchain is just going to get rolled back and they weren't going to profit, it may deter them. And if they still want to hack knowing they won't keep the coins, well then they are just vetting the blockchain security for free!
