Just wait for the winning time of your gambling session and after that winning time then its the time for you to run out of the site together with the money you are playing with or play with another site and aim for a specific amount of bitcoins.Because after that winning streaks in a site they will strike you back and take all your money,
What if after several try you are still not winning and you are already finishing your money? If it is me before losing twice i will run home quickly. You will never really know when you are going to win but losing is always sure.
