In my own term I'd be stopping already at the amount of 30-40% in my budget, It's stupid to risk all your money in a day, I know that luck does not strongly base on what your games would be, but rather than to know if you are actually playing the game right or you are just playing the game to win money without even using your common sense, learn how to restrain yourself, or else you'd be using your feet all the way onto your home.
Similarly I stop when I reach to my daily limit and I have got so good at having fun with smaller amounts that I do not even reach my daily limit anymore, I just bankroll like 5 dollars at most and than stop because I already have couple hours max to gamble and if I bet like with 10 cents or less (which is still something in bitcoin gambling) than reaching to 5 bucks everyday takes a lot of time (unless you hit some horrible losses streak) and during that time I already had enough fun that I usually just stop, hey I even made profit some days instead of losing which I put on top next day
.
Even my inner thoughts are insisting about continuation of my gambling, the lessons I have learned will not allow me to do so. If I have not make use of my previous experiences with gambling, then I could not survive in this gambling field as how I am today.
