In real play, everyone must win with such a bet settings in short period. Plus it is always better to test with Doge before first play. Players can face two problems - too low balance for fast win, and trying to get too high win in one time. Much better is stop the game in right time and withdraw. 
In fact, you are wrong. Even if you plan to exit after first winning bet there is a probability of hitting killing strike that will start with first bet and... this probability is bigger than expected profit from this system.
I've calculated this somewhere in this thread ->

What i'm saying is if your target is 10% profit than you will have bigger probability of succeed if you go to any dice site, put your whole wallet into single bet and set reward to 10%. Martingale (and any variation of it) is only reducing probability of reaching target.
