2sandykho47, can you prove that? Best do it as quick as you can if so. Sign a message from an address associated with it. Op, it's also silly posting from the account you're trying to sell though as that's a good way to tarnish it.
Do you mean signing a message using a bitcoin address ? If so, i have one
