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 their bitcoins because most of the time they need it in emergency case. Another reason is because they need fiat than digital currency which is only limited for transactions compared to fiat which is worldwide. And common reasons are doubt about bitcoin's future, doesn't have enough knowledge about crypto coins and the strategy of "buy low, sell high. There are many reasons.
Yes, there are different reason of why people sell their bitcoin and i agree that because they badly need fiat than crypto currency. Another thing is maybe they are afraid of the current situation of bitcoin and they don't want to gamble the situation to wait if it will come back to its high price again, and lastly is the fact that bitcoin really needs the fiat to maximize its value since it cannot be used to purchase any direct goods in a small stores so it should be converted into real money.
