Well live you can only play one table at a time, and if I am not mistaken 30 hands per hour is decently fast for live. Online you play about 60 hands per hour at any one table, and you can play 10 tables at the same time if you like, so that's now 600 hands per hour.
If you
study the statistical
variance of a game like poker, even being a decent long term winner, you will find that it takes thousands of hands to have a near certainty of being in the
green. Decent winners regularly experience loosing streaks of 10000 hands, even more. Live that is 333 hours of play. That is a whole month if you play 12 hours a day.
If you
study the effect of
rake over your win rate, you will find out that a very significant portion of your potential gains are eaten up by the
rake. The
rake can actually
turn a marginally winning player into a looser. The smaller your average long term win rate, the more the
rake will eat up your potential profits, and the more likely it will make you a looser.
Online at the
microstakes, the
rake is about 6 to 7% on decent sites, less when you get to 50nl and up. Live it's 10%, not counting that you have to pay for your drinks,
tip the dealers and the waitresses, etc.
On the other hand, live games are generally softer than online games for a given
stake. If you play 50nl live, it's a MUCH softer game than 50nl online.
But the 30 hands per hour, the
rake, and the fact that you have to play
tight to beat the
low stakes live games, you'll die of boredom before you start learning anything. I am used to play 8 tables of cash online (about 400-500 hands per hour), I tried live cash and it's painful. The only times I like to play cash is with friends while getting drunk and smoking weed, or in tournaments.
