That's how casino counter the martingale strategy. Most of the bankroll won't keep up if they experience 20x losing streak. You need to have a ridiculous amount of capital to keep up with a very small base bet if you experience that kind of losing streak. This is why I don't do martingale only strategy on a casino since I've lost so much money just by doing it. It's an effective strategy but the risk of it will certainly drain all your bank rolls. I suggest to just use different strategies when you are doing a gambling session or mix some strategies.
I disagree with your point. Casino's don't need to counter martingale strategy, nor it's effective. It's mathematically proven to be not a good strategy by any means. It's based on gambler's fallacy and human's inability to understand probability or big numbers.
People can say that they understand how probability works, but we are intuitively wired to not grasp it. So we want to use it as we see more meaning into it. It's just as effective as any other method. All based on luck and probability
I think that a casino with a particular game, whatever the strategy, the casino will always have the advantage, that is something that cannot be denied, however, if a player uses the martingale it is a very reckless strategy, I do not recommend it Under no circumstances, because things can get ugly when it comes to playing like this, you can also win, but I think that the risk is not worth it, even when another type of strategy is applied, because the chances of winning are the same for a player As I have said, the advantage of the casino is always Evident.
sports betting is the only option in my opinion that can make profit in the long term if people have good knowledge about sports betting and also do not have house advantage in sports betting, so it is possible that in the long term a person with high knowledge about gambling manage to beat the bookmaker leaving with profit, but it is a long learning path until people manage to have some strategy to make money with sports betting and there are few people who manage to make these profits
now when it comes to gambling that depend on luck, there is no strategy that can beat the bookmakers, but there are people who manage to be very lucky to hit a large multiplier and with that get big profits, but these are very rare cases. rare, and if those people who won a lot keep playing then there will come a time when they will have lost everything they managed to win, it is very difficult for people who play the games of chance that depend on luck to control themselves and have a good money management
