We should all ask ourselves a very simple and straightforward question: is CBDC something that arises from the real needs of central banks, or is it the result of the fear that governments have of the growing popularity of Bitcoin and some other altcoins? It may be both, but I think the latter is a much more significant reason why governments of different countries are working on their development. The ultimate goal is to maintain control over the financial system, and centralized digital currency is a real nightmare for every user when it comes to privacy.
I read the article from the link posted by @tyz and there are some interesting things, like a statement like this :
At a Senate hearing in February, the Central Bank of Nigeria (CBN) Governor, Godwin Emefiele, famously described them as ‘money out of thin air.’ In an interesting turn of events, the CBN is using the technology behind this “money out of thin air” to create the eNaira. It revealed on July 22, 2021, that the pilot scheme for the project will begin.
Time will tell what will happen with this project, but it seems to me that it will share the fate of the Petro project in Venezuela, pompously announced, today no one is talking about it anymore.
