cryptocurrency from the government in my opinion will not last long and of course it will cause a lot of conflict, the government makes its own cryptocurrency because it wants to try to manipulate investors and wants to make as much profit as possible and make many investors suffer, therefore many traders do not like currency from the government.
States will issue and are already issuing their own digitized central bank currency. This is not a cryptocurrency, but an improved system of their cashless payments. Because their CBDCs will have better functionality than their current cashless payment system, CBDCs should be around for a long time until something better comes along.
Since CBDCs are state stablecoins, they will not be of interest to traders as a way to make a profit.
Yeah the government has launched CBDC, at EURO and US.
At China , the government have digital yuan.
I think many government will launch digital currency, but not crypto currency.
They will have centralized platform and being controlled by the government.
The government should learn about decentralized platform, But It seems difficult to happen.
