Imagine that some respectable country would go far beyond legalizing cryptocurrency and start one of its own. It would surely be no scam and it would probably have a strong support, but would there be any drawbacks to the currency and the state itself? Would it get more attention than some of the biggest coins now?
I am sure that the creation of a new coin by the state will create a very strong push against the crypto economy. I find that a small unrecognized state that can do such maneuvers. After all, they still no one recognizes, so they have nothing to fear.
