I agree, but disagree.
No Limit has those swings, I've wons a few thousand, and lost a few thousand in cash games. I fair far better in tournaments. I don't know, I have lost more on no limit cash game for whatever reason. I guess tournament play doesn't translate well for me in cash games.
Yes, limit or pot will def get you some bad beat, but its a game you can control the odds, and know because its cheap people play shit hands, and you can more often then not grind a profit.
I think I'm going to transfer some of my bit coins into a online poker, its technically legal.
