Question for people who have tried crypto trading bots. Do they work? Have you made any profits with them or is it a scam mostly?

I have never tried trading bots while investing in cryptocurrenceis.

As far as I understand, they are bascially making an analysis, a prediction of the price based on some parameters, buying and selling - making trades.

Basically trying to do the opposite of what we are doing all the time - buying high, selling low.

You are suppoused able to set some parameters on bot app based on your own needs.

Then I read that there are some bots that are buying coins for a lesser price on one exchange and sell it on another exchange where that coins is at higher price. For some reason it sounds just wrong but looks like that is what they do. On this sub, people are talking about bots destroying reddit avatar minting gen3.

I have no idea how bots work, I have a clue because I read a little bit, but anyone here tried it? Is it worth it? Which one should we take a look at?

I never tried it because I am a little bit skeptical about it, if it worked everyone should be making money which is impossible, right?
