Trading bots is a good thing in my opinion, if you want to make time for other things that you want to do while still doing trading to earn money then trading bot is for you, or if you want to maximize your profit, it can also be a possibility that you will use a trading bot for another account while you are doing another trade with another account. I think that automation of strategy is already a feature of trading bots and yes it can make money, but that can only happen if your strategy can profit and you know how to tweak the bot to match your fool proof strategy.
