If a person does not have much time but is passionate about investing, buying and keeping is the best option. At the moment the price is relatively low so if it is me, then I will buy and hold at the present time.
Holding is the perfect strategy not only it is a very easy strategy to implement for those without time you are also going to get better benefits than most traders since trading is a zero sum game which means that if someone wins then someone else needs to lose so by definition by just holding you are ahead of 50% of the traders and that is not a small thing at all.
