It's crystal clear that CBDC'S are digital fiat currencies that is meant to replace the paper fiat currency system, to be operated and controled by the Central Bank of a country and I don't think they're in compition with Bitcoin, but rather, are going to be using the Blockchain technology to operate which Bitcoin is father to that very technology ,I do think it will even help in more adoption and growth of Bitcoin in general, in the sense that it will now become clear that Blockchain technology is the future that means more interest would be on the superior coin which is Bitcoin that uses same technology to operate.
