Poker players and especially Better poker players can Sell their PokerStars Play Chips for real cash. Some players want to Finance their Money games and this can be done by selling their Play Chips which they have earned through many hours of online play.
The advantage to this is that "If you think you are ready, Why not start playing Money Games." There is nothing wrong with this approach. Financing your money games based upon your Play Money skills is OK. "Poker," is a game of skill.
So have fun ~Chips,
