Still won't give any effect to bitcoin, believe me. Again, CBDC is fiat, what do you want fiat to do other than make it a means of payment? You want to make it an investment? Impossible. Then why should we be afraid of CBDC?
I repeat, CBDC's just a means of daily payment, to buy burgers, tacos, Pepsi, pay rent, etc.
Some governments promote CBDC as a better and safer crypto so there will be some impact as decent number of potential Bitcoin users will not learn about it enough to start using. In another hand using digital money will give an experience of doing so and motivate some others for learning more and to know about Bitcoin what is an impact also. May be impact will be not too big but some impact will be.
But yes, CBDC is just another form of fiat, I totally agree.
I think it is not going to be an alternative to bitcoin but more like alternative to usdt, which means that there will be a lot of people who will use it, and it will be very much liked. All these people who claim that it will hurt crypto do not know what they are talking about, if a government is doing CBDC that means they are actually promoting crypto to a point and that's a good thing.
I believe that we are going to be doing just fine and it should be something we really enjoy and promote ourselves as well. If a government accepted it and uses it, that means they are actually quite fine about crypto as well and that means we can promote crypto saying the government promotes it as well.
