Obtaining the best possible chance over beating the house can be simple yet risky. Betting systems have been put in place for decades, however common negative progression methods may just be the best way to increase your odds to win. All negative progression methods are strategies that are typically designed under all of the same guidelines. Simply put, all have the player increase their wagers after a hand is lost. Some negative progression methods such as 'Martingale', 'D'Alembert' and the 'Fibonacci' all have such similarities. However, choosing which one works best all depends on the player and their bank roll. For instance, the Martingale has the player not only increase but doubles their bets after every loss. This usually equates to players needing a pretty big sum of money in order to use this strategy appropriately. Unlike the Martingale, the Fibonacci uses a similar method but doesn't double the bet after the first loss. It actually has the player follow an interesting mathematical sequence (1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144). For example, if you bet $20 the first bet your following bets would look like this, (20$, $20, $40, $60, $100, $160) etc. All that is happening here is you're multiplying the first initial bet by each number in the sequence stated in order. Negative progression relies on the fact that after generating a loss, a win in theory should have a higher chance of happening. This progressive tendency makes the Martingale have an edge while on a losing streak. The higher a losing streak becomes allows the chances of a win soon to come. It is this 'factual assumption' that can make this way of betting dangerous. All-though math dictates after losing a hand should increase your chance to win the next is true, players assume this advantage and can turn a player bankrupt. Is gambling this way worth it in the long run some players may wonder? It just depends on how lucky you truly are. Of course, negative progression has some sort of fact bearing evidence behind it that points to being a relatively wise way to gamble. But players all around the world have seen detrimental losses gambling like this. Just because you flip a coin ten times doesn't make it impossible to land tails all ten times. If a player decides that this way of betting is how they want to play, finding what betting strategy best suites them is important. Gamblers should be aware of the possibility of landing a losing streak, and incorporate that into deciding if negative progression is really the right way to play.
