A cryptocurrecy issued by a government is stupid by definition:
It doesn't seem stupid if any government around the world issued cryptocurrency to her citizens. One thing is sure in this case, that, the said cryptocurrency issued by the government will neither be a decentralized cryptocurrency rather a centralized platform for transacting digital currency.
................is that the country can't technically go bankrupt and the coin can't become a scam.
On a clear note, the country can experience bankrupt even though it's tagged to cryptocurrency. The best about this cryptocurrency is that, it can never be a scam unlike what we are experiencing on coins without value.
