The Fibonacci System is a betting strategy based on the Fibonacci sequence, a series of numbers where each number is the sum of the two preceding ones. In this system, players increase their bets following the sequence after a loss, aiming to recover previous losses when they eventually win. This method is often used in gambling games like roulette or sports betting. While it can help manage betting amounts, it does not guarantee profits and carries the risk of significant losses if a losing streak occurs. Players should use it cautiously and be aware of their limits.
