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. 
if you double your betsize for every loss, you will end up wiping away your balance...
I am doing that with my free BTC given in some gambling sites and my free balance just sweeps away quickly. I don't know if free BTC is a great amount to do that strategy but I don't think it is not.
Small amount don't really do great with that strategy. Some time the wins are more than the lost but most of the time, the BTC I am getting from it is less than doing random bets.
