It would be very nice if every country will have its own cryptocurrency.There are many countries thinking about creating their own cryptocurrency.That can make the crypto-world more popular among people, and help spread crypto all over the world. But it may take a few years.
But unfortunately it will make crypto currency alone farmers but will not serve the exact purpose of crypto currency to the people. I am also believing many countries will be interested in creating their own crypto currency but it will create another altcoin and nothing more than that.
Having a common decentralized commentary system alone will be the only solution for solving many financial problems with which many countries are struggling right now.
