Auto bets utilize the martingale methods I've tried it on dice games and I had mixed results sometimes I won but most of the time I lose it's not excited using a bot in my experience it takes away the joy of risk betting I always do manual betting so I can change my strategy and my variations from time to time if you have a huge bankroll and had a good combination on setting your bot you can employ it, but the house always wins the game.
In the very beginning, bots are not intended to increase your chances your winning.
Be it using an auto-bet feature, bot script, manual betting, or any kind and something along those lines, all your bets will face the house edge, and your probability to win at each of your bets will still be under the provably fair of the site.
Bots are used to follow the preferred betting style of the user without doing manual work. Save time, convenience, and less hassle - these should be the common reason why users use bots and not because it's profitable or can change the users' probability to win.
