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 ?

No i'm not working for BiteBTC.
I only tried to withdraw BTC, and received the deposit within 24hours.
