They make you really believe that is more like a skill and if you are good at it, it works.
My friend told me that is just about how lucky you are, and not a skill.
So, should I stick with holding or playing day trade is a better option?
I bet it is just pure luck, if that thing even exist, because day trade is too risky to be done. And also, it is not so profitable, you will not use the money enough because its too little. So i suggest, we should just hold bitcoin, for a longer time because it will just help us more than we thought it could be.
