Yep, and now the Copy Trading option being available at most centralized exchanges makes this belief stronger among newbies. They believe they can do copy-trading for the rest of their lives and earn money without having to learn anything but they are wrong. You can't rely on other people all the time, even if you can, it will only be for a short term and you will eventually have to start doing your things yourself instead of relying on others for that.

As a trader, a person needs to understand everything. Not only as a trader, but in anything a person does, he must know what he is doing, otherwise, he wouldn't have any idea what is good and what is bad, and in this ignorance, they can lose a lot of money without even being able to understand how they lost the money.
