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,
That's a good idea, when you know that you win already and good amount just left immediately in that site. Because if you not leave the game its possible that you lose your winning. Don't greedy instead think the risk while you gamble. For example your luck to win on the first game and until the second game, then that's the time for you to leave the game.
