For those saying avoid online poker, one of the best use cases is practicing for live games. I used to play 100's of hands per hour at 2/4 and 3/6 to practice for live games up to 40/80.
I think we are trying to say the same thing. I agree that the quality of play at an online 3/6 game is way better than .01/.02.
What's the point of .01/.02. Might as well play with play money.
Well for 0.01/0.02 No Limit the buy-in cap is usually like $2 but as you amass chips you still get to play whatever you have on the table so even though it appears to be a mere penny game bets getting as high as $6 or $10 all in bets are not uncommon. So if you don't know what you are doing you can still drain your bankroll just as easy any other form of gambling.
For a person like me who still needs a lot of study and practice for No Limit it allows you get those hands in and start to confirm an actual win rate and if you are playing at a place that allows easy record keeping of hands played you can get start to build analytics of your play which really can help you improve your game.
