Thanks for the link. Here's a lifehack for betting on roulette...

Martingale System:
Initial Bet: You start with a small bet, for example, 1 unit (you can use any currency depending on the game).

Even-Chance Bets: You place your bet on red/black or odd/even — these are the options where the probability of winning is close to 50%. These bets typically have a winning probability of about 48-49% (due to the two zeros on the roulette wheel in European roulette).

Doubling the Bet After a Loss: If the bet loses, you double it. For example, if you start with 1 unit and lose, your next bet will be 2 units. If it loses again, you double it to 4 units, and so on.

Recovery of Losses: Once you win, you recover all of your losses and make a profit equal to your original stake.

Example:
First Bet: 1 unit on red. (loss)

Second Bet: 2 units on red. (loss)

Third Bet: 4 units on red. (win)

You won 4 units but spent 1 + 2 = 3 units, so your net profit is 1 unit, which matches your original stake.

Risks of the Martingale System:
Large Losses During Long Losing Streaks: If you encounter a long losing streak, your bets will quickly escalate, leading to significant losses. For example, if you start with 1 unit and, after several losses, reach 128 units, the total amount of bets can easily exceed your bankroll.

Betting Limits: Many casinos set maximum betting limits, which can become a problem if you need to continue doubling your bet. For example, if the betting limit is 100 units and you reach this limit before recovering your losses, you won’t be able to continue doubling your bet.

Psychological Stress: Constantly doubling bets can cause significant stress, especially if you lose several times in a row. This can lead to impulsive decisions and even greater losses.
