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?
Most likely, we can only be interested in the centralized country's crypto currency. It will be like more convenient use of national money. Centralized crypto currency of another state is unlikely to be necessary if we just do not intend to visit this particular country. Therefore, it seems to me that centralized crypto currency will play a certain positive role. In addition, such a crypto currency will help restore confidence in the decentralized crypto currency.
Yeah that will be the big benefit that the government issued coin will be authentic and there will be nothing of scams. This thing will grow their coin in the market and the people of that specific county would invest without any hesitation. If the government does tax its coin for some time, then can collect investment from all over the world.
