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 personally sell it to cash since I need cash to pay, bitcoin is not yet available for payment here in our country. I convert bitcoin to cash, but not all because I started using bitcoin for the main reason of having profit so if I would not sell it, I will not have profit since I cannot use bitcoin in real life transactions yet. I know this have negative effect but sometimes I seriously need money to use on daily living so I cannot refuse to convert it to real life money.
