Hey im searching for someone who will sell me 3.7 BTC. Im willing to give 20$ each.
Ill pay first.
(Please dont point out that i have no feedback and that im a new user, i know that

)
I don't think it's that you have no feedback that people will take issue with, it's that you're requesting to make payment through a highly reversible method. Perhaps if you offered payment first through a moneygram, moneypack, or western union people may be more incline to take your offer.
But then again when a new user offers high prices above market through paypal it's usually a scam.
