Wouldnt it be nice if each country in the world issues its own crypto currency just like they issue sovereign bonds and they raise funds from there to fund projects in their economies. I know Venezuela tried to do something like that, but the project was already being killed by the governments opponents before it took off. Now lets assume that didnt happen could it be a good way to create some form of sanity and confidence in the crypto world.
The emergence in each state of its own centralized cryptocurrency would be useful for the whole cryptocurrency as a whole, since people would see that their state is interested in cryptocurrency and would learn to use it. The states' cryptocurrency itself will actually be used primarily within this state and, in fact, is only a digital envelope of the same centralized national money. However, in general, such a cryptocurrency would be useful for increasing the popularity of the entire cryptocurrency.
