My e-mail got recently hacked and all the accounts associated with it, but i had a signed message here with my personal BTC address, so what are my possibilities to claim back my original BCT account?
I think you might get your account recovered. theymos or badbear will ask some questions that only you would've known to make sure that you're really the owner of that account.
you should do it fast because if your account get sold you might find it harder to get it back.
