In my opinion, only long-term holdings and instant selling of two options, when I start long-term holdings, I will not pay attention to market trends, and when I trade every day, I will not hesitate to sell!
Long term holding is not for traders because they will have to trade for making money. Long term investment is for those who have no experience of trading or they do not have time for trading. They can only buy and hold their coins for long time and when they realize that the price is quite good now and they can make money while selling their coins then they should sell their coins.
