Martingale vs Fibonacci: Which Strategy is Better?
Progressive betting strategies like Martingale and Fibonacci promise to overcome losses. But do they work? Let's compare.
The Martingale System
How It Works
Double your stake after every loss. One win recovers all losses plus one unit profit.
Sequence: 1 → 2 → 4 → 8 → 16 → 32 → 64...
Example ($10 base)
| Bet | Stake | Result | Total P/L |
|---|---|---|---|
| 1 | $10 | Loss | -$10 |
| 2 | $20 | Loss | -$30 |
| 3 | $40 | Loss | -$70 |
| 4 | $80 | Win | +$10 |
After 4 bets, profit = $10 (one unit)
Problem
After 7 losses at odds 2.00:
- Total staked: $1,270
- Next stake: $1,280
- Risk: 10

The Fibonacci System
How It Works
Follow the Fibonacci sequence: 1, 1, 2, 3, 5, 8, 13, 21, 34...
After a loss, move one step forward. After a win, move two steps back.
Example ($10 base)
| Bet | Stake | Result | Sequence Position |
|---|---|---|---|
| 1 | $10 | Loss | 1 |
| 2 | $10 | Loss | 2 |
| 3 | $20 | Loss | 3 |
| 4 | $30 | Win | 4 → 2 |
| 5 | $10 | Win | 2 → Start |
Advantage Over Martingale
Slower stake growth = survives longer losing streaks.

Side-by-Side Comparison
| Factor | Martingale | Fibonacci |
|---|---|---|
| Stake growth | Aggressive | Moderate |
| Recovery speed | Fast | Slower |
| Bankroll needed | Very high | High |
| Max losing streak | ~7-8 bets | ~10-12 bets |
| Risk of ruin | Very high | High |
The Mathematical Truth
Both systems fail because:
- No edge — Betting on coin flips at 1.90 odds has negative EV
- Betting limits — Bookmakers cap maximum stakes
- Finite bankroll — You'll eventually hit a losing streak you can't recover from
Long-Term Expectation
With 4% margin and no edge:
- Expected loss per bet: -2%
- Systems don't change this math
When Progressive Systems Seem to Work
Short-term success creates illusion:
- 90% of sessions end in small profit
- 10% end in catastrophic loss
The catastrophic losses > accumulated small wins.

Important Note: Progressive betting systems like Martingale and Fibonacci don't work on skill-based games like video poker, where optimal strategy and correct hand decisions matter far more than bet sizing progression. For these games, focus on learning perfect strategy rather than betting patterns.

Conclusion
Neither Martingale nor Fibonacci creates profit from negative-EV bets. Use them only for entertainment with money you can afford to lose.
For real profit:
- Find value bets
- Use proper bankroll management
- Bet with an edge
