You can use any strategy if you are lucky, martingale is good for people who are not lucky in picking bets so they want to try many times and if they'll win one bet, they'll win back all their loses, and I would say this is a bad strategy for unlucky people especially if they don't have the discipline.
Your statement is quite confusing. How can you mesh strategy and luck, they are much different!
They are different because strategy is what you follow when you are gambling and you could either win if you are lucky and lose if you are not, that if you are believing that winning is based on your luck, if not, you won't consider it, just a pure strategy and wait for the result which is you will lose or win.
If you can win only based on the luck, it means you don't need any strategies.
what I'm saying is you can use any strategy and you will in if you are lucky.
Regarding martingale, I don't think it is an effective strategy for betting. Some gamblers even got more losses by using that strategy. I suggest to learn it more before you conclude it is good or not to use.
You can follow the strategy but the result varies from user, some are using it effectively while some are not.. you are saying that is not a good strategy but that is only based on your experience or opinion.
