As you know that you need to stop and leave the game? How can you feel this moment. I almost always lose their money because they can't learn when to leave the game. I'm not sorry to lose. I have a lot of money not to lose, but I can't keep the winnings if I'm lucky.
The right time to leave is the moment you land the site. There is no guarantee you are going to win. If you are ready to lose and you dont care of losing they you dont even have to think of leaving. You can fight till your last breath and last penny left in your wallet.
