I agree why you are going to stop someone from selling everything if that is going to be their main source of living? Or you just wanted them to keep holding the bitcoins that they have so when the price is going to increase they are going to earn some interest rate as they are just going to hold it for a longer time.
If bitcoin is only source of your income then you will never prefer to hold them longer without selling them as you need money for your expenses so you will surely sell when you see higher price.
if bitcoin were the only source of income i guess the current price doesn't matter,what they need is to fulfill their need and if your needs weren't fulfilled because waiting for the high price or price rising,then they will die waiting for the right time to sell without eating any foods lol
