Turned $50 into $1000 playing on Pokerstars 8 years ago. Promptly lost most of it when I went to the higher levels. After that I just played for fun in the lower levels. Haven't played in years though, so not sure what Pokerstars is like now.
Tough to beat the opportunities offered on PokerStars.
EVERY SUNDAY you can play a $300,000.00 Gtd Sunday Storm for an $11.00 buy-in,or even The Gtd Sunday Million for a $215.00 buy-in.
