why some country banned bitcoin?

[passioncrypto]

They banned bitcoin because no one can control bitcoin ,and many people use it as a way of crime,money lagging is more easy with it .But bitcoin is also a way to income of common people, so government should prevent this kind of bad use of bitcoin not to banned bitcoin.

Simply put, Bitcoin is decentralized and therefore not controlled by anyone. As we know, because they like to control currency, the government has formed a currency. They control it through the central bank. They also want to know who has, where it is and where it is. Although they can't treat Bitcoin like Bitcoin. Therefore, I may conclude that they are afraid of something they cannot control.

Firstly bitcoin is decentralize and if a country is 100% control by decentralize currency the country will face some problem in the future.  The banks and centralize government will suffer heavy impact from illegal trafficking to all sort of problems which might occur.
