Negative Progression
Money Management System
Negative Progression Money Management Systems suggests that a bettor significantly raises his bet after a loss to recoup the lost bet and get a profit.
For example, you start at $2 in a Blackjack table and lose in four straight hands. Then, on the fifth hand, you win! For simplicity, let's just say that all the bets were even money.
You would have lost $2+$4+$8+$16 = $30 on the four losing hands and won $32 on the fifth hand.
The losses were covered ($30) and you had a profit of $2 (equal to the original bet).
But what if your original bet is $20 and the maximum bet on the Blackjack table is only $100? After the third straight loss, you won't be able to double up because your bet will be more than the maximum limit.
Generally, Negative Progression Money Management Systems are regarded as dangerous because bettors can lose their entire bankroll after a losing streak.
A popular Negative Progression Money Management System is called the Martingale Betting System. It is said that many players have gone broke using this system than any other betting systems out there.
