Just make double bet, when you loose, and make your win, then withdraw. In first round, it is very rare, if you have 10 red strikes, so you can make win fast, even today. 
That is too much risky. If you will keep double your every strike, in fact no one know that what will happen, some time even your 15 consecutive strikes comes negative which cause a very big lost for you. So you need to make some limit and after that should play gambling.
