Are u even seriously asking it? Let me answer the questions for the OP.
I'm new here ! I have 1,709 BTC . I want to sell urgent. Banking, Skrill , PayPal, Escrow . Good deal and go.
Is that 1.709 BTC or 1709 BTC? It is a big difference between the two of them

.
I'd say it's
BTC 1.709 given that's what it is in the OP's thread header...
I'll start the ball rolling by asking can you sign a message from the Wallet Address the BitCoins are in?
Sorry, I can't sign a message, because I have the bitcoin in exchange.
Did you know that PayPal is a reversible method of payment?
Ofcourse I know, but I just want to scam.
Are you prepared to go first?
Oh hell no!
He is selling bitcoin. The fact that paypal is reversible is a problem to him!
Also, if you use an escrow, the escrow will get the bitcoin first so they will be able to prove ownership of the coins that way won't they?
