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

Why would anyone want to share their winning strategy if it works 100% against the casino, your friends might have won some money using that martingale strategy, but the main reason is because they are on a lucky day while gambling on the roulette game that specific day, so I would strongly advise everyone to take caution when gambling with any strategy that claims to be able to beat the casino.
