i'm selling potentional hero member for 0.08 BTC your price is high.
Yours is a potential hero member account but presently a senior member account. This is a hero member account with huge activity nearing Legendary Status. So, I guess the price isn't high.
You'll never get a buyer for such price and with no signed message, no matter how positive trusts you have.
I think most of the escrow would refuse to escrow account deals without signed message or other proof of ownership
Instead, I am thinking of
reducing the BIN price to 0.38 BTC.
