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

Martingale strategy always works on any kind of gambling including roulette but never use it for a long run, because it's really dangerous to use it for long run. You can busted easily, so just use it for a short run like 10-20 minutes or until you get a nice profit.
