I think holding a bitcoin for a long time is a good thing cause the value of bitcoin keeps on getting high just think about this when bitcoin made its first appearance the worth of 1Bitcoin is 0.08$ look how much its price grow from its appearanve
to me i think it depending on the interest of the people, as some people are always interested in long term investment, while other people do not good in long term investment as by nature they cannot wait for such a long time and they always give preference to short time investment.
