I wish to Londons New Bitcoin Exchange is not the next Mt. Gox.
Even if the owner of this new exchange runs away with all the coins, the cops will catch him, unlike the situation in Japan where Mark Karpeles is still freely roaming around enjoying his life.
He might not be for long though. Doesn't the US want him to answer some questions? It wouldn't surprise me if he's found guilty of fraud or criminal negligence or something.
