You can even recover account without having access to a connected BTC address, by sending an e-mail from the registered e-mail id. There are previous cases of such account recoveries so it should not be an issue always.
Well I have two mail. Deleted my old messages. So I'm little confused which is the exact one that I use for the account. Though I have send a message to the mail which is showing there when I tried to log in. And I think I have sent the message from the right mail. Hoping to get reply from them.
I guess this would work if you could sign a message from that address you posted. It is pretty easy to sign a message if you are using
Blockchain.com for it.
I tried but this method isn't working. Can't find more option there to put signed message. If you have blockchain wallet can you check it please.
