You'd think that country that has issues with tax compliance and has already done things like removing large denomination bills would want to move to a fully traceable currency.
Furthermore it would make even more sense that it would use a currency of its own creation rather than one that isn't under its own control.
I think most of finance has accepted that cryto currencies are the future, it just won't be bitcoin or Etherium but rather a currency for each country/region just like fiat currencies we currently have.
