who can help me to return my account from a hacker, I have attached my profile to my ETH and Bitcoin address, but I read on this forum I have to make a signature with my Bitcoin address and this is my biggest mistake, because I use the Bitcoin address from exchange not from Bitcoin wallet, can I use Ethereum to do it? I can prove that it is me by sending a transaction using the ETH address that I entered in my profile.

please help me, thank you.
