Based on my experiences , it doesn't. I always end up losing especially when autobetting

I completely agree with this because in last few days I try autobetting on few dice sites and all gone against me even no one give me any profit
There are some dice sites has a good feature on their auto betting where you can set the max win/max lose/max bet, so you can prevent lose all your coins.
if you ask me, those autobet features are only implemented because the casino owners themselves know that martingale will fail in the end, and having the system implemented with as many features as possible to encourage players to use it will benefit the owners in the long run.
Dice sites have autobet bot because their players ask for it and want to bet as fast as possible, so why not make your customers happy while making the owner (and investors) happy at the same time?
