But I guess people think of bots as 'tricks' to earn.
Quite right. A bot is just an automation of your knowledge and skills, few people want to sit at a computer all day and watch the price, in this case algo trading helps. And those who think that there are some universal settings that will make the bot work with a single button, then they strongly doubt it, I put such traders in the same category that uses copy trading, telegram signals and others. These are naive people who think that they can outsmart the market using these methods of earning and can get rich on it, while not delving into anything. This will never happen.
This is the difference between an expert trader and a novice one. A novice one will use the default given strategies and hope that we would get something in return, and that would be a bad idea, I do not suggest doing that because it will not be that much of a problem or help for you at all.
However, if we are talking about something that is profitable in the sense that we could make a profit but we want to work as little as possible then the best thing we could do right now would be to learn how to trade manually first and if we are great at that then we could become great at how to use a crypto trading bot as well and use the same system on it.
