CBDC is not to be disregarded for any reason. They are government backed and are even more powerful than cryptocurrency. They are powerful because they are widely adopted, they are legal tenders and also national reserve currency. Because we are crypto educated and know how to maneuver our ways does not mean everyone else outside there knows how to handle these situations.
There are people we recieve their salary in fiat and if CBDC is fully inplace, they Will start receiving salary in CBDC. What of people who pay import and export duties in airports and sea ports. The use of fiat is wide and so CBDC will be. It will not make sense for we to ignore CBDC because it is a rising technology birthed by cryptocurrency.
