Everyone expects a benefit?
Not necessarily, but usually yes.
Also, please let me correct my wording... when I said "Thanks for the sarcasm." What I mean is; I appreciate the skepticism. I know I have no reputation, but this could allow me to gain some reputation after a few transfers for people.
I've heard people saying that you can charge paypal back only if you pay with a credit card, this might be completely wrong, feel free to call me an idiot. But if that's true it means that someone who transfers paypal credit to you that hasn't been funded with a credit card won't be able to reverse the transaction if something goes bad.
In the opposite case you're putting yourself at risk.
(Feel free to correct if my understanding of paypal is completely wrong)
If you want some reputation maybe you should do some OTC trades.
