I'm glad you got your account back. Apparently,  I have bought the account from BCT member Kummerf before even knowing that such account was a hacked one. When I bought it from that user, I decided to resell the account without first making a research about it or even requesting a signed message from the seller itself.

I am sorry for any inconvenience this may have caused, but it seems that I have been scammed and lost my BTC.
