doesnt stop him doing a charge back (up to 6 months?) and if he did want to scam you would'nt the obvious thing be to pay you for a small sum of coins only to run off with a lager sum he later gained with his newfound "trust"? Your braver than me for sure!

Besides its not like PP is a miracle solution to the "complex" process of sending money. Escrow is the way to go, and even a 3-legged, blind,brick-hooved donkey can use WU or whatever.

Note to OP: I'm not accussing you of being a scammer, you might be genuine BBBUUUUTT, as I'm sure many have learned the hard way, never trust the stranger in a hurry!  . So if you are trying to scam: go fuck yourself!, if not: have a look at some of the scammer related threads so you dont sound so shady.
