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.
People sell bitcoin to get profits due to its high price. Now a days bitcoins price going high and still with some exception price going high. So peples prefer to sell bitcoin.
In reality there are chances to rise price and breck previous records but due to fluctuations and unsecured behavior of bitcoins market people prefer to sell it.
