What is Bankroll?
The dedicated pool of money a bettor uses to place wagers, kept separate from living expenses.
A real bankroll is the line between recreation and edge. Every unit sizing scheme — flat-stake, Kelly, percentage — assumes a bankroll number that does not change with mood. Disciplined bettors review and rebalance the bankroll on a fixed cadence (weekly or monthly), not after every win or loss.
