2. Fork the blockchain to block the stolen coins and effectively destroy them.
Vericoin will survive. Hacker has no coins. No threat to system. Coin amount reduced, value goes up.
Mintpal customers lose, this is Mintpal and the hackers fault. Mintpal needs to reimburse.
Mintpal could die.
Sorry, but I believe this option 2 doesn't exist at all.
