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.
You hodl to sell some day when price has appreciated, so you can't keep it when you are in dare need.
On the other hand, the reason that you sold when price has gone up is exactly why people will sell.
