Why Betting Systems Cannot Beat the House Edge
Martingale, Fibonacci and D'Alembert reshape the distribution of outcomes and nothing else.
Progression systems adjust stake size based on previous results. Martingale doubles after a loss, Fibonacci steps through a sequence, D'Alembert increments by one unit.
None of them changes the expected value of a single bet, and the total expectation of a series of bets is just the sum of the individual expectations. Because each bet carries the same negative edge, more turnover means more expected loss.
What systems do change is the shape of results. Martingale produces many small wins and rare catastrophic losses, which feels like it works right up until the sequence hits the table limit or the bankroll.
Independent events have no memory. A roulette wheel does not owe you red, and no staking pattern converts a negative expectation into a positive one.
