I also do not know they are more happy with dice bots, maybe they are tired to do dice, so they prefer to use bot, if I prefer manual, because the result can we set its own
Dice bot can be configured to do different strategies what need more fast calculations, impossible to do in our mind fast enough to make it worth. Dices do all the calculations very fast, you don't need to worry about it.
They can configure it to stop before a big loss too, what helps a lot to don't lose the bankroll so fast.
