here's the problem with a rollback: You sell me 100 oz. of GOLD, not fiat, not bitcoin, not pork bellies (tho the pork bellies wld be same as Au) for an equivalent amount of VRC.
You and I agree that VRC has value, so we agree to the exchange, I send you VRC, you ship me gold coins.
A bad man steals many VRC from MintPal. Blockchain gets rolled back. I get my VRC back.
*But I Still Have Your Gold.*
You win the arguments fight, end of discussion!
I'm not a VC supporter, but I can't stop being revolted by Mintpal's behaviour.
They make an horrible mistake with their poor security and then they asked (or threatened ?) the devs to reverse the blockchain...
Poor devs, all their work beeing destroyed like that because of a so bad company...
