The two most used strategies in betting are Martingale and Fibonacci, systems which rely on mathematical calculations.

## MARTINGALE

Martingale Method dates back to 18^{th} century, having its origins in France. This method was developed for simple bets with 50% chance of winning, like throwing the coin. The strategy consists in choosing a front, heads or tails and doubling the stakes after each loss, so that after the first win, you gain back the initial loss plus an extra profit. But, any system can adjust. For the strategy to be profitable, the minimum quota of betting has to be at least 2.

Regardless of the method, this has to apply for achieving results.

Imagine skipping the fourth stage, and in that exact moment achieving the result you’ve desired.

A simple example is the one below; if we double the stake until the 5^{th} bet which is a win, we gain back the whole stake we have played so far and make a profit of 1 unit (1 unit represents the amount of money suggested for betting). After the winning point, we start over.

Stake(units) | Quota | Amount won | |
---|---|---|---|

1 | 2 | 0 | |

2 | 2 | 0 | |

4 | 2 | 0 | |

8 | 2 | 0 | |

16 | 2 | 32 | |

Total | 31 | 32 |

**Profit (winning amount-stake): 32-31=1**

## FIBONACCI

Leonardo Pisano Bogollo, known also as Leonardo Fibonacci, was an Italian mathematician considered by some to be “the most talented mathematician in West Middle Ages.”

Fibonacci is known in the World of Gamblers for a string of numbers, which has his name- that is Fibonacci String- which he used as an example in his book “Liber Abaci”.

In Fibonacci String, each number represents a sum of two previous numbers, starting with 0 and 1. Thus, the string (the stake in the case of gamblers, expressed in units) starts with 1,1,2,3,5,8,13,21,34,55 and so on.

In contrast to Martingale, for the strategy to become profitable, the minimum quota on which the bet is placed has to be at least 3. So, they are betting on an event with a quota of at least 3 and the stake is raised each time they lose, until the moment when the gambler wins.

A simple example is the one below, when the 6^{th} bet is a win and we gain back the whole betting amount and make a profit of 4 units (1 unit represents the sum suggested for betting). After the win, we start over.

Stake(units) | Quota | Amount won | |
---|---|---|---|

1 | 3 | 0 | |

1 | 3 | 0 | |

2 | 3 | 0 | |

3 | 3 | 0 | |

5 | 3 | 0 | |

8 | 3 | 24 | |

Total | 20 | 24 |

**Profit (winning amount-stake): 24-20=4**
