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.
basically, bitcoin is banned in your country? you better stay low with the bitcoins! might get you in trouble.
People sell bitcoin because its an investment and that what it's suppose to do.
