I don't think so. But it's probably worth a try.
Doesn't verify for me. Admin's probably won't accept an eth addresses anyway so please provide other sources.
A signed message from a bitcoin address is likely the only thing that is going to get your account back. If you can't provide that then you should at least try sort the ethereum one out.
Why can't you sign a message with your BTC address?
My bitcoin address is from coins.ph I can't sign a message with that site. But I can offer to open my coins.ph account to prove that I'm the owner of my account.
I tried. I already pmed cyrus but no reply.
