Hi, I have been playing online poker for about two years. I have never really played with a ''bankroll'' mentality, and have always just put small amounts ($50, $100) on various sites to play .25/.50 nl texas hold em. Now, I understand this is completely out of my bankroll, but I do not have the money to cover a .25/.50 legitimate bankroll. Now while this can be fun, I have decided I want to get serious with poker and develop a bankroll so I am not constantly putting on $50 at a time when I want to play. Lately, I have been doing really well playing heads up, 9, and 18 man $5.50 tournaments. I am just curious as to what a good bankroll would be for these $5.50 tournaments, and what I should be playing if I have $100 for it to be considered ''safe''. Thanks!
