I tried doing martingale strategy as I have read some success stories of gamblers about it but I must say that it is not for everyone. I had a bigger risk because I believed that I can recover from my losses by increasing my bet. A gambler who continuously applies this strategy can possibly lose a higher as he tries to win back his losses. I don't think it's profitable especially if we will apply martingale in all the gambling sessions that we have. I'm sure that experienced gamblers can also testify the same thing.
Whatever strategy you apply, basically the luck factor plays the most big role. in fact, everyone is entitled to use any kind of strategy in a gambling session, or we can say some kind of technique or method. but what is certain, whatever the methods, strategies and techniques, gamblers must be prepared to lose the money they risk. especially, in luck-based game types.
To be honest, I don't dare to take the risk to use the martinggale method. however, in fact we can work around this without having to double every round in the game. I mean, we can wait for the right moment to multiply the bet in one round. but still, there is always a risk. and most importantly you must first understand how gambling works, we can even apply it to the type of game you will play. The most important part, gamble for fun and not for instant money.
