Did the technical work succeed? Does the exchange operate in standard mode?
From my side all is functional, i can trade, deposit and withdraw.
So since the maintenance, you can login your account again, and you can withdraw your crypto (what kind of your crypto?) normally ?
Well, but you're just a new bitcointalk account which registered on 4th Jan, are you from BiteBTC ?
