Trading does require good knowledge and also skills in order to make a profit. besides that, we also have to be patient in waiting for the crypto market to go up and down, don't be in a hurry because it will make our minds chaotic and also panic. Most people fail at trading because they panic about the crypto market that is going up and down and end up selling it at a low price. Besides that, I think trading cannot be used as the main job, especially for people who are not really good at it, so it would be better if we don't rely too much on trading before we can do it well and upgrade our skills.
