Strategy won't work unless you are very lucky.
I usually run reversed martingale and set multiplier 2.3 - 2.5 and increase bet on win by 90%. Sometimes I win and more times I lose, overall I am in negative.
I think that if long losing streak is possible then winning streak should be possible too. My goal is to hit 15 successive greens and to win more than 1btc. So far, I have never win more than 12 times in row
