The CBDC has been piloted in a number of countries, essentially the CBDC will not pose a threat to bitcoin and it will even have a clear regulation for the exchange with bitcoin. Maybe or won't they? Anyway, with the CBDC, the government has begun to acknowledge blockchain technology and it is a moment of truth that they cover up.
Which countries, I am pretty curious because the only one I know is the Digital Yuan from China. I do think so because most CBDC have a framework similar to cryptocurrency but I have heard they put tracking on it so more like a digital money.
