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,
It's better to set some plan and target amount first before you deal with gambling since you are not able to determine when that winning time is coming and you should not only be focused on aiming and leave after hitting your target, you must leave the game as well after a straight loss not only because you have nothing left to place a bet because you need to manage your funds as well as the losses .
