This mostly happens in dice sites because people mostly use strategies on dice like martingale or many others and those strategies mostly make you bet bigger amounts when you lose just to recover the losses and at the end you will have nothing to make your bet double because you will lose everything.
This is the common things that usually happen when you are playing dice games. Yes, martingale and other techniques that make double of your bet when you lose is such like suicide and doesnt guarantee you always win back your losses previously. No matter how big or small your bet is the only thing is for sure that you would still lose in the long run.
i think anybody who has ever tried gambling has this experience especially the bad experience with dice games.
when you start the auto bet with the martingale strategy and then go away and come back to see the whole page is filled with the red results and your bankroll is empty.
