What do you think about this possibility ? Would you invest in your government currency ?
It is possible, because the crypto currency is the future technology. It will be needed in the future.
A government can create a cryptocurrency but the cryptocurrency is a currency having no center and not controlling from any center so government must design a decentralized cryptocurrency. Adopting own cryptocurrency of a government is also very good and will play a key role in the economy of country. Digital currency saves money for you and saves money on your transactions as well as it saves money for government that were using in the manufacturing of paper notes.
So, what's the difference if the government has to design the cryptocurrency they make should have a decentralized system with them adopting existing cryptocurrency such as bitcoin or ETH?
The government made own cryptocurrency intend to arrange all system to get some profit from all user who has their cryptocurrency. But if government design cryptocurrency who have to decentralize system this is very unreasonable.
