When I send $100 USD to you, then I got $50 BTC from you. next 2 days I disputing you and got $100 + BTC, so what's your profit?
The real scenario is I sent $100, you fast withdraw your PayPal and disappear.
Exactly that would be the real scenario here.
First post offering such bogus activity.
I hope no one will take the bait from this user.
And this user will get his "karma" if he is already doing it and screwing naive users.
