CBDC is not only introduced in America, even in many countries this project has been tested for launch. CBDC is a government product, that means it still has the same relationship and rules, so there are no advantages offered by CBDC and for cases of threats to bitcoin travel , I don't think it has any major influence and has no relationship that could threaten the future growth of bitcoin.
I don't think this will be that much of an issue since the so-called "Digital Dollar" is still gonna be governed by the Federal Government which makes it not decentralized, unlike Bitcoin.
But what do you guess?
Nothing can threaten the journey of bitcoin, because this asset has a much better bargaining value compared to fiat currencies and CBDC, decentralization offers complete freedom for holders, so that we can regulate ourselves regarding deplation rates. Setting what is meant, you can still hold back when a decline occurs and wait for the recovery process to make a profit, another advantage of bitcoin is that it can retain value that fiat does not have.
That's why bitcoin is growing until now, bitcoin is also a speculative asset that has the potential to go up or down, this will play a role in the supply and demand system.
