Do you not realize what will happen? It will go down like this. "Hey man, can I trade you for your 2nd (Insert Exotic Here)?" "I guess so. As long as you trade me a bad exotic, you will have to pay $20 to my paypal." "ok" 20 mins later... "why didnt you trade?" "the money didnt go through. Try it again." then he pulls money out of this guy. forever.
