My account was hacked and someone changes my email address and password and now I have no access to my account but I locked that account immediately when I know that. I created this temporary account to recover my account.  I have only added ethereum address in my profile https://bitcointalk.org/index.php?action=profile;u=1128677 and when I checked, it requires signed message with bitcoin address but no bitcoin address is in my profile. Can I sign through my ethereum wallet which is already added in my profile to prove the ownership of that account? Any helpful reply is appreciated.
