The US has theirs but it's known to be the Libra.
This is not true, the U.S. are working on launching it's own CBDC called the "digital dollar" and not libra. Libra is a coin owned by Facebook.
The question is how it is going to fare with crypto and how it's going to affect us, will it be successful or not?
It's not going to affect us (decentralized crypto users) in anyway. CBDC's are centralized currencies, that will be more or less the same with the countries fiat currency, only that it's going to be digital. Most of the advocacy to launch digital currencies by some countries is only for political reasons, we've seen how the U.S responded to the digital Yuan, with their own digital dollar, it's more of politics for most of this countries and it's not affecting Bitcoin or any other decentralized cryptocurrencies.
