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 think that both things are needed. You can have really great luck and no skills in trading and earn much more than even the most experienced tough trader.
I do agree with you, bro. However, even the long-term trading needs some luck. However, the day-trading is a real science and art. The skills are needed.
