How Bankroll Growth Works
Expected Value
EV measures your average profit per bet. Positive EV means long-term profit, negative EV means inevitable loss.
Variance & Swings
Even with positive EV, short-term results vary wildly. Larger samples smooth out variance.
Stake Sizing
Smaller stakes reduce risk of ruin but slow growth. Kelly Criterion finds the optimal balance.
Compound Growth
Reinvesting profits accelerates growth exponentially. This is why bankroll management matters.

| 3% | +30-50% | 3-8% | Moderate |
| 5% | +50-100% | 10-25% | Aggressive |
| 10% | +100-300% | 30-60% | Very Risky |
Pro Tips for Bankroll Growth
Track Everything
Record every bet with odds, stake, and result. You can't improve what you don't measure. Use a spreadsheet or betting tracker app.
Start Conservative
Use 1-2% stakes until you have 500+ bets proving your edge. Many think they have an edge but don't. Protect your bankroll while gathering data.
Expect Variance
Even +5% EV can show 10-bet losing streaks. Don't change strategy during downswings. Trust the math over short-term results.
