You cannot be sure of this, and there is no fact that points to this, apparently the only country making such claims happen to be China,i do not see the reason why countries would create it's own cryptocurrency,when they can manipulate their very own fiat currencies..
If you search in the press, at least more than ten countries stated this. Therefore, all this is only a matter of the future.
Even if such creations happen to come into effect,they will just be creating some other Altcoins/shitcoins and it has absolutely nothing whatsoever to do with the bitcoin,how it works or it's nature..
We already have over 2000 Altcoins,they will just be additions to those numbers
national crypto currency is a secure national currency - this is not some shitcoins
