I only play at pokerstars when they have a bonus. And i always cashout(after the bonus) with less money then I deposited. I make between 1.5 and 3bb/100 at PP though(depending on stakes) so I know I am a winning player. But stars, never fails me. I deposit, go on a downswing, and cash out with 20 bucks less then I had. However I will continue to do their bonuses. I know variance is a pain in the ass. So from now on I am going to let them stack, so i can actually put in a good 10,000 hands and see what my winrate really is at stars.
