But, that is funny when someone share their strategy in this forum and when people see it, it is martingale strategy. Maybe that person get win on their first time and not feel lose yet. But, back to gambling's nature, it is luck game and if luck not on our side anymore, we can end with empty our money. But what make it funnier, someone who use martingale and then sell their strategy. 
It is true. When using the martingale strategy, I guess people are having different experiences, so that is why people keep sharing about their strategy. But be careful if you want to use this strategy for a long time because there is no guarantee you can get the win. After all, you should not use too big money using any strategy, so you don't have to feels bad about losing the money. And yes, that is funny if someone says that he's got a big winning with this strategy, but that is possible if he has luck.
No strategy strategy in gambling about bankroll management that will make gamblers wins all the time, martingale is just part of the strategy that will make you loss as losing streak is possible, what you just need is to improve your guessing skills because if you win more you will certainly make more money, provided you have the discipline to manage your funds
martingale with big money is bad, it might only bust you when you are too unlucky, and that might cause big regrets, believe me.
Both of you are right. It's only a matter of time before we lose all of the money. All gamblers can use that strategy, but we need to remind that any strategy that we used doesn't guarantee us to win, especially to make the most winning. Discipline can help us to prevent the loss, and that will work well with controlling the money we used so we can avoid losing the money in one day. Improving the skills in gambling can be a solution, but we need to remember that we always need the luck to win.
