Digital Yuan only helps in increasing the exposure within the non-crypto community folks but still, there will be hassle of converting the coins to corresponding nation's digital currencies but we need a common universal currency like bitcoin rather than each nation launching their own digital currency.
I think you misunderstood the fact that bitcoin will never be a universal currency, no organization will ever do that, no government will want a currency be running under their feet. China's action towards crypto community is huge, they have these central banks operating for their own digital currency, and as far as I know it is not only China that has been doing this. As we worship bitcoin to be an innovative work of art, we cannot blame others to innovate bitcoin too, faster and reliable too.
