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?
All you need to do is follow the instructions in this
thread It may take a while, but theymos should deal with it eventually, if he hasn't replied to you within a week or two, send it again. Make sure you do it right though, he'll probably ignore the message if anything is wrong on it without letting you know.
