the martingale strategy really sucks, I'm better off using the flat betting strategy in all of my bets, I prioritize long-term profits rather than dreaming of big profits in a short time
I've used the martingale strategy but in the end I had to sell all the items I owned, that's really a strategy that doesn't suit me
If by chance you would have been successful following Martingale, then the strategy would not have sucked?
In the end you can only maximize your chances, but in a casino your odds are always going to be lower than the house.
This means that no matter what strategy you use, if you keep playing, you will lose all your money. It's math, no matter how good the casinos try to change your perception.
