Martingale is a typical casino betting system. In games where you have a 50% chance of winning you double your bets every time you lose. But no method is infallible, it has limits:
1- Betting sites limit the amounts you can bet
2- Gamblers do not psychologically and economically withstand series of likely
consecutive increasing losses
3- Every player does not have money and unlimited time
4- The outcome of future bets is completely random, it is impossible to make predictions
So I believe that the unsustainable long-term martingale. Do you agree? Do you think it can be called a strategy? Did you use it or would you use it?
