## Staking Is Not Just About Money
A staking strategy determines how much you bet on each selection. Done correctly, it does three things:
1. **Prevents ruin:** Ensures losing runs do not destroy the bankroll
2. **Captures edge:** Stakes appropriately more on higher-edge selections
3. **Enables compounding:** Grows stakes as the bankroll grows
A bad staking strategy can turn a profitable selection process into a losing operation.
## The Spectrum of Staking Methods
From simplest to most sophisticated:
**Level Staking (Flat):** Same amount every bet. Simple, predictable, widely used.
**Percentage Staking:** Fixed % of current bankroll. Adapts to bankroll size.
**Kelly Criterion:** Mathematically optimal stake based on edge and odds.
**Fibonacci, Martingale:** Systems based on chasing losses (universally ill-advised).
## Why Strategy Matters More Than Selection (Sometimes)
Consider two bettors with identical selection abilities (both identify +5% EV selections equally well):
- Bettor A: Flat stakes, 1% of bankroll. Slow growth, almost zero ruin risk.
- Bettor B: Doubles stakes after losses (Martingale). High ruin risk regardless of edge.
The identical selection process produces radically different outcomes based purely on staking.
## The Risk of Ruin Calculation
For any staking strategy, risk of ruin = P(bankroll → 0 before any positive goal).
This probability depends on: edge size, bet variance, stake as % of bankroll, and the number of bets.
The key insight: stake too high relative to bankroll and edge, and ruin is likely even with genuine positive EV. Staking strategy is the difference between extracting value and destroying it.
