To me bitcoin is there to gives you money when you're satisfied to take the money or take your if can't wait when is dropping. I can't hold for too long is personal or I will never take investment in a short is till personal.
Whether you hold or not what will happen in bitcoin will still happens, is good to hold but too long hell no, because am not the future, future is expectations real life is in the present.
Nobody has urged us to hold forever. Besides, we have our own decisions and control of our Bitcoin, and we can sell them anytime if we want.
We can hear that many individuals are suggesting holding during the bear season but it was reasonable because it was not ideal to take that option (selling) when you are losing. The price of Bitcoin doesn't just pump up after buying that is why holding is should be applied. If we are familiar with this cycle - buy, hold, and sell, meaning we accumulate today and sell later when the price is already profitable, and that is investment.
