I am very new to this concept, i just recently saw someone advertising to sell there play chips for real money. Now, first off has anyone here done this? Actually before you answer is this actually legal or allowed on pokerstars to sell off your play money chips for real pokerstars money?

Anyways if anyone can shed light on this for me i would appreciate it. Because if it does turn out to be a legal thing, i have a ton of play chips from my early days of playing that i guess i could make a lot of money on. But if its not through pokerstars wouldnt it be easy to get scammed, or is there some system?

Im just really clueless on this whole matter and would appreciate if someone could give me a little summary of it. Thanks
