There is no strategy that would work 100% all the time, If there is a strategy that could win 100%, all casino would have already shut down their doors. There is two reason why this strategy of yours won't work, firstly you would need a super huge bankroll as I have seen 20 reds in a row before in a real casino, and there is also a table limits for outside bets in roulette, there will be a point which you eventually can't increase your base bet anymore if you lost many rounds in a row.

Secondly would be the house edge in roulette that gives the casino advantage over the players, because there is the Green 0, your winning chance is actually not 50% playing the black and red. The more rounds you play, the higher chance you would stand to lose all of your money to the casino because of the house edge.
