Yeah haha, if you don't want to lose big amount of bitcoin it is better if you are going to quit already in your gambling career.
So that your tears will not fall easily, or if not manage to put some limitation on your bet or else you are really going to cry.
Gambling requires preparation emotionally and financially haha.
Saiha's right you should put a limitation - you should set only a certain amount you are willing to bet. When you lose, then game over stop playing.
And before you play, set your mind that the money you will put out is already gone so it won't hurt when you lose (but of course, do your best to win).
