Gambler can get some advantages from using bots as well as disadvantages.To get a good bot or software he must spend money. On the other hand the bot should be set properly. But here you are not guaranteed to earn money. Moreover, you will be deprived of the pleasure of manual betting in gambling. I don't use gambling bots and do not intend to do it.
Gamblers very rarely use bots because it misses the fun of gambling, actually the function of bots is to automate gambling with settings that can be set on the bot application, so there is no reason for bots to be used for profit because there is no guarantee of profit, even if the bot can make 80 % win then it is certain that the developer will not expose his app and he never sells it.
A bot is several times more powerful than a human and can do any task instantly as per the commands set in it. A gambler may win most of his bets using bots but he will only get the fun of money but not any fun of gambling. There are many people who gamble to make money. Bots can be a useful tool for them. But bots are not a good tools for those who gamble for fun.
