And even if you use a bot, you still have to make settings on it so it can run the way you want. But if the market immediately reverses, you still have to set up the bot again. And that means you must still have the knowledge and ability to use bots properly.
Having a bot don't guarantee anything but it automates your trading which will save you time.
It's true that there's still a need to setup the bot and you can't just buy a bot and expect that it will bring you profits on an instant.
Making such with bots is a combination of your knowledge in trading and also what you know about the market. There are newbies that think you'll get profits easily by just having that but no.
Automating our trading time is fine if the market conditions have moved better and are still improving, but we know that market conditions often change, which means we have to be able to see how the market changes, and if necessary, we can rearrange orders we have done before. If you can live with the consequences of running a bot, you can keep using it. Otherwise, manual trading will be better for you because you decide when you trade. And it also won't require you to check the bot frequently to see how it's set up.
