If you didn't posted or stake any bitcoin address its impossible recover them back.
If you posted ethereum address i think you can sign message to the ethereum address but better to contact theymos or cyrus about this if its also allowed or not..
If they accept it you are lucky if not better to continue to use your new account..
Did you tried to use the email recovery instead? or you just forgot to change your password before?
You should verify that you own your account can you share the profile link of your account? i just wanted to check if the email or password was reset recently. .
After hacking, the hacker changed email, pass and added security questions. I tried but I couldn't recover. That's why I locked my account from the link which I get from BCT in my mail.
And I also read it but I haven't such any btc address.
That's why I signed my ETH address.
Here's the code.
{
"address": "0x79c884b963a2138bc8ee8df4646743631a9eaff1",
"msg": "My account SHAHJALAL has been hacked. Please reset the email to [email protected]. The current date is 11/11/2017.",
"sig": "0x87f1d695fddb9634e5ef2bf0163848f5b09977a3f4f8e6dc579f1fd3d7e69bf0674af55c7bbaf6df79c756f56e960abca8236829695b4ce63fa2901c8e6eee441b",
