If you dont use Escrow no one will deal with you.

Because your just another scammer, to make you go away quickly and stop wasting everyones time do the following -

1) Post the wallet address of yours that is holding the 10BTC
2) Post a signed message from that address to prove its yours.

Bet you cant and log off shortly to register a new account to try a new scam

p.s. a bit strange how you made 1 post almost a year ago in russian then you pop back up out of the blue with 7 posts today all trying to sell BTC
