but it will be something other than bitcoin and something that a governing body would launch.
They have launched it already and it is also called fiat. I am referring to Central Bank Digital Currencies (CBDCs). It has not better usage than fiat and countries that are creating it said they are created with blockchain technology but that they are not cryptocurrencies but fiat. No better usage than fiat.
It's fiat with more levers to control it.
It's also just a fancy name for it for people to get interested and invested into it time and effort-wise.
