Die Einheiten-Regel

Nie mehr als 1-5% des Bankrolls auf eine Wette. 1 Einheit = 1-2% des Totals. Bei 500 € Bankroll: 1 Einheit = 5-10 €. Standard: 1 Einheit. Hohe Zuversicht: 2-3. Nie mehr als 5. Eine 10er-Verlustserie (statistisch unvermeidlich) verliert nur 10-20%.

Ruinrisiko

1%-Einsätze mit 55% Quote: Ruinrisiko ~0%. 10%-Einsätze: ~40%. 25%: ~85%. Bankroll-Management ist der Unterschied zwischen 10 Jahren überleben und in 3 Monaten pleite.

⚡ CalcWolf Insight

The single most common mistake recreational bettors make: chasing losses by doubling bet size. This is a martingale strategy and it has a 100% probability of catastrophic failure given enough time. After a loss, bet the same amount or less — never more. Your edge comes from selection, not from sizing.
