Martiangle is a very good strategy, you can earn a lot of money from this strategy, but be careful not to use this strategy too much if you do not want to lose all the money, because many bookies are committing fraud.
martingale strategy more likely looks you are waiting for your bankroll to get busted by red streak and not to profit.. thats why i stop gambling on dice sites to avoid martingale coz i once loved that strategy
