It's not rigged it just feels like it is. If it was rigged all those big names like Poker Stars and Full Tilt would have huge law suits so far up there ass.
I played online poker for about 1 1/2 years now Inter. I made a little bit over 2k with it on PokerStars wich is nice. I am by far one of the best players at NL50 but I just could not win anymore for a period of 4 months I played break even. It's not rigged thats true, but if you don't enjoy it anymore it's just pointless.
