Well, I don't care how many articles you share, those articles were written by human beings like you and I, they shared what they believe, and I am here sharing also, what I believe, and my believe is that martingale is not gambling strategy, if ever it is a strategy, it is a strategy for the gambling casinos to make more money for themselves, not a strategy for the gambler.
Gamblers who practice martingale in gambling believing it will increase their chances of winning are complete gambling newbies, if you also believe in such, then you are also a newbie in gambling.
And you don't have to make anything clear to me, I have brains so that I can think for myself and don't have to follow everything the crowd says or believes in.
Martingale is not a gambling strategy for me and that is it, believe it or believe it not, it's up to you bud.
When you follow a certain pattern, e.g. when you increase your bet two times when you lose, do the same until you win and when you win you start from zero again, what can we call it other than a martingale strategy? Word strategy means a plan of action designed to achieve a long-term or overall aim (source Oxford Dictionary). I am not here to teach you something but martingale is really a strategy in gambling.
Is it a good strategy or not? My answer is that you can't beat luck with strategy. It doesn't matter whether you follow Martingale, Paroli, D'Alembert, Delayed Martingale, doesn't matter if you follow it long-term, short-term, you can't beat luck with strategy, that's why newbies usually win at first but lose when they learn the game.
