Many countries including Venezuela, China, USA, Russia and others are planning on launching their own cryptocurrency since the growth of Bitcoin has caught the public eye. The difference between the decentralized and centralized cryptocurrency (CDC) lies in ownership or lack of it thereof.
The anonymity, maintained in decentralized currency, is one of the major factors which has attracted mass attention. The dearth of privacy in CDC, meaning that the government and anyone in the system can view the transaction details while controlling and denying it if they want is probable. Governments, possibly insecure of their future in the national economy, due to the mass adaptation of cryptocurrency have decided to join the game.
Even though Russia has an intent of taxing its black markets through its cryptocurrency, not all intentions are malicious. Using CDC is going to be much cheaper than using credit cards or paper money, due to the lack of middlemen. Another benefit of the CDC may be that interest rates may be altered, according to personal needs.
