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.
The fact of the matter is that without the experience of manual trading, it makes no sense to use algo trading. But there is a category of people who believe that the bot can even think for them and has artificial intelligence that can independently analyze the market.
People ARE lazy. Watching prices all day is being lazy 
Why watch price all day when you use algo trading? It's like watching the price every day when you are a long-term investor. People in this case are not lazy, but stupid and do not understand what the bot is for. They try to hammer nails with a microscope.
