do you guys know something like steamgifts or steamtrades for origin?

I have no idea and I don't care.

u can trade origin stuff there. but not accounts.. Account trading is not allowed afaik.. Both steam n origin

It's allowed, scroll down and read here. The only thing that cannot be traded are what steamtrades considers to be exploited keys. Of course make sure you specify that you have Origin keys. I remember seeing one guy who refused to specify that all the keys he had were not Steam keys. Never completed any trades, just a really sneaky guy with no respect for the people he was trading with, just wasting their time.

Of course account trading is also prohibited by Origin and Steam but Steamtrades doesn't mention this ;)
