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?
Every investor wants to make his/her fortune in stock markets. But, your dream will only come true depending on your own skills as well as luck. Your luck can help you to beat others in stock markets particularly for short term. However, in long term scenario, your skills will always outpace your luck depended performance.
Generally, roulette wheels & lotteries are known to sit on the luck side while swim & crew races are on the skill side. However, stock investment is known to reside in between the two extremes i.e. skill & luck. And, you cant separate your skills from luck. You need to adopt a perfect balance between the them.
