not sure if its save on retail also , but what i want to know is.

is it save to trade epics for nothing? (i payed fg for that item)

or is it questionable when a stranger gives me or someone an epic for nothing.

no one knows? how is it on retail?

Well if none of you mentioned d2jsp or forum gold i believe you should be safe, although you could always give other person something in return like random item or some gold so it looks legit
It is illegal to trade like that so you're always risking when doing it

trade some random white item or something so it's not as suspicious

If you don't talk about it in game at all, purely just open a trade and accept a trade, there is a really good chance you're completely fine.

i would say to the trade , lets pretend we are friends and i just buy the "epic" for cheap from you so you have some gold as a thanks.

strange part it , i will never see or write with him again xD
