I'm not sure if I have time to play with charts and trade a lot, like I have seen some youtubers doing.
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?
you can try day trade using a little portion of your fund, lets say 10%. and trade when you have inside information. sometimes luck plays a factor, but in crypto, you should have insde info, like gov't announcements, project announcements, and gossips. these have vital roles in pushing price up or pulling price down. if others have inside info and you don't, then you're in the losing end.
