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,
This is for the winner only! How about if they encounter losing? What possible things that can do? They play more games to back there money and wait for the luck to get a winning? Or stop to play and play for another day?
Base on my experience, leaving in the middle of the game with winnings is not easy, your opponent are disagree especially when they want to recover over the unlucky games.
We're always focus on winning then run anytime they want. But did you think that others want you to play in other day? This will be a negative feedback for other player and also to ourselves.
