Bots are really just tools being used by traders themselves to automate some of the things they're doing in the first place. It's not some run-once-and-profit-forever thing.
But trading bots for me is not really advisable for the newbies or those people is starting to trade, learning from the scratch first is much better before using some automated tools.
I agree with that, newbies should focus more on the manual trading to practice not relying on those trading bot. The only importance of trading bot is to let you trade even when you're working with your job. You will just monitor it when you have a free time and let your trading bot manage your account. Also, you need to know the pros and cons of using crypto trading bot because the consequences of using it will reflect on the results and you are accountable for that. That's why most of the traders are recommending you to practice manual trading to completely and easily manipulate your money and your account.
