Your bankroll is the amount of money you’ve set aside to gamble with.
You might have specific bankrolls for various games based on various goals. If you play games where you’re satisfied with a negative expectation, the size of your bankroll compared to the averagesize of your bets is what determines how long you’re able to play a specific game.
If you’re a professional gambler, though, you’re probably more interested in avoiding going broke in the short run. Gambling is based on random chance, and even if you have a long-term advantage,you can still go broke in the short run because of variance.
Here’s a simple example of how that might work.
Suppose you’re playing a simple gambling game with a buddy where you have a 52% probability of winning, and she has a 48% probability of winning. She’s willing to bet you straight-up, too — ifyou win, you get $100 from her, and if she wins, she gets $100 from you.
Suppose you only have a bankroll for this game of $100.
Can you see how you’d have a good probability of going broke even though you have a distinct mathematical edge?
In the long run, your results should resemble the mathematical, theoretical prediction, but in the short term, anything can happen.
The goal of having a large bankroll relative to your bet size is to avoid going broke while you’re waiting for your long-term edge to kick in.
But that only applies to gamblers who have an edge.
