Hi guys is there anyone knowing anything about Martingale strategy? I'm new on it and i'd like to start to use it in online roulettes. Do u think that it worth trying using it if my budget is roughly 2k£? I found this guide
https://casino.guru/roulette-scam-strategies and they say it's better not to use it; but i have friends who won real money thanks to that.
Can anyone giving me any further info about? Thanks very much

Anecdotes do not cancel the math, many people hear stories about people doing something against the probabilities and winning but whenever that happens is just an anomaly, over the long term you will be a loser if you go against the probabilities.
The martingale system seems to work precisely because of that, people see that with the martingale system they can only lose their money if they lose several times in a row and when they see that they think it is impossible for that to happen, but it is not, and when you finally lose enough times to break the system you will lose all your money, so please before betting in the roulette take the time to read more about it, since it has been proven that the martingale system simply does not work.
