CBDC is centralized and has nothing to do with Bitcoin and its value because bitcoin is solving a lot of problem for individuals and gives them privacy because of its decentralized nature. CBDC still have the same value of local fiat currency of any country that is created their own CBDC and that does not change anything when inflation comes, the value will still depreciate.

Bitcoin is not just a currency but also an investment since the value of increasing overtime and that will make more people adopt bitcoin and dump their country's CBDC only if they're forced to use it by their government. Bitcoin has come to stay and the price of bitcoin will keep on increasing in value overtime due to its potentials and freedom that it gives to users.
