Worldwide, especially in my place, must sell it for profit rather than always keep it!
The government always forbids the use and play bitcoin so that it can not grow fully potential in my place. Surely it remains an advantage if there is a transaction rotation for bitcoin in my country to live.
I think that is because they have already earned their target profit. For me, I am gonna sell some of my bitcoins if I reached my target profit, we all know that bitcoin is a bit of a risk, or should I say, it is very risky to hold bitcoin for a long time, and it is because of its volatility, maybe that is one of the reasons why people are selling their bitcoins as well.
