In whatever form the government will come up as regard to owning their cryptocurrency, it won't change from being called the same name as cryptocurrency, and it must have a Blockchain based network just like every other coin/tokens cryptos. I think that the earlier some other countries embrace crypto the better for the growth and development in their countries because crypto has come to stay and it is another form of money that will definitely compete with the fiat currency usage, and may even overtake fiat in my opinion.
