I think as follows:

when someone buys bitcoin and earns bitcoin that person must set a price target where he will sell, it is not possible for the person to simply say: "I will do HODL..." and do not know when he will sell.

Today the price may be $18,000, 4 years from now $100,000, but the person may not have the same health or lifestyle in 4 years, for that reason it is necessary to set a price target to sell
