The Martingale is a betting strategy that originated in 18th-century France. It involves doubling the bet after each loss, with the idea that a win will eventually recover all previous losses plus a profit equal to the original bet. This method is often used in games of chance, such as roulette or blackjack. While the Martingale strategy can seem appealing, it carries significant risks. A long losing streak can lead to substantial financial losses, and many casinos impose betting limits that can prevent the strategy from being effective. Therefore, it is essential to approach this method with caution.
