...It would be more plausible their account might be under 'close scrutiny' by their bank/financial services with millions of funds in and out and potential fraudulent wire.
It seems obvious to me that Unicredit has frozen their account, yet most seem reluctant to accept this possibility. All it takes is one bank employee to press a button.
Even if that was the truth, after investigation by their bank they must come to the conclusion they aren't doing anything illegal by running a bitcoin exchange. Yes they were missing the proper licenses, but surely this can be resolved by mtgox actually getting them and maybe paying a fine to the authorities. So I think in time, their accounts will be unfrozen.
Bitcoin-24 get their account frozen and never get unfrozen.
