This is stupid, how can you show proof? And why does it matter anyways?
"You need to prove that you are the true
owner of this account by signing a message from an old associated btc address or an reputable user
that verifies your ownership via pm. "
It matters, because a lot of people bought hacked accounts...
@blumangroup
yes, I bought this account

-BTW: I don't have internet for the next 48 hours. I will answer all questions/pm when I am at home.
