Sure you make money fast playing NL 200 but you lose it fast too. Bankroll management is the key to not having to redeposit. If you want to be successful playing any type of poker in the long run, you have to minimize your risk of ruin by making sure you are properly funded for the games you play. 700 dollars is far from properly funded for a 200 NL game.

There are a lot of bonuses out there to help you build your bankroll up, some sites offer better ones than others, but the bonuses don't do any good if you lose more clearing them than what the bonus is worth. Again, bankroll management.

Keep reading FTR and practice at limits within your bankroll.
