Bankroll

Bankroll management is the discipline that separates sustainable betting from gambling to ruin. The core idea is that stake size should be a fixed fraction of the pool rather than a reaction to recent results, so that a losing run cannot wipe the account out. Common approaches stake one to two per cent of the bankroll per bet, or size positions by perceived edge using a fractional Kelly criterion, which scales the stake to the size of the advantage.

The concept matters beyond strategy. Treating a bankroll as ring-fenced money, deposited deliberately and never topped up mid-session, is one of the practical behaviours that responsible-gambling tools are designed to support, which is why deposit limits map so directly onto it. Chasing losses is, in bankroll terms, simply abandoning the staking plan after a drawdown. Operators see the same variable from the other side as player value and lifetime deposit, and the divergence between those two perspectives is at the heart of most affordability debates.
