Yeah, I don't like CBDC too, it doe not alliened with the cryptocurrency concept of decentralization which makes it unnecessary to run side by side with Cryptocurrency, being a Centralized government back currency.
There are countries campaigning for CBDC because they want to monitor their citizen's transactions at all cost. I think CBDC should not operate on the blockchain because it may increase regulatoins.
The idea of a central bank digital currency (CBDC) is totally not worth it, I see it as a direct competition to Bitcoin and cryptocurrencies, meanwhile CBDC frankly cannot stand the competition with Bitcoin, it would only be a waste of taxpayers' money. In my country Nigeria, when the central bank was cracking down on Bitcoin and cryptocurrencies 4-5 years ago, they introduced CBDC but guess what? today a lot of people including the banks have forgotten about this system, nobody talks about it including the media, meanwhile billions of taxpayers' money was used to settle some Switzerland fintech company to provision and maintain the system.
