I have been using the Martingale system on freebitco.in. This is the system that states that you double down after every loss in order to regain your losses and still profit. I know that the Martingale system is one doomed to fail in the long run especially with the house winning 52.5% of the time on that particular website. But by betting small amounts at a time I have managed to multiple my winnings by an incredible amount. I have gone from .000007600 Btc to .001 Btc in a matter of hours. My question is can this system be used and be successful if you bet small amounts in order to maximize your chances of winning the small prize?
Essentially you've hit some lucky streaks and therefore you probably ought to quit while you are ahead. The more you gamble the more you'll eventually close in on the long-run expected average of the game. I'm not sure exactly what that is in this game, but you can be sure the house is coming up with the money they're paying you for the captcha solve and then some (when you fail on the gamble). It's a game of averages, the wins are in the short term so if you're on a good win streak, quite while you still can.
