Martingale technique is not effective to use unless you bring large capital to continue to be doubled in every dice game, I will also change the game pattern to default mode to avoid high losses because dice games are unpredictable and only depend on luck factor without any guarantee technique used for winning predictions.
Even though you have large capital, it doesn't have any guarantee if the martingale technique will always work! actually you're doesn't need large capital to do that, just play with smallest bet. First you said martingale technique is only effective if you have large capital, but in the end you're said there's no technique to win in dice game, you're contradict yourself.
The person you are quoting is indeed contradicting himself, however when it comes to the martingale strategy there is a lot of evidence that has proven over and over again that it does not work, it does not matter how small your initial bet is and how high your capital can be, martingale is a strategy in which sooner or later you will lose all your capital if you play for long enough, now it is a strategy which may give the idea to the gambler he is in control as it seems so unlikely to lose so many times in a row, but the more you gamble the more likely this outcome becomes.
