CBDC may also be an opportunity for Bitcoin to help increase scalability and liquidity, it will make Bitcoin more priceless.
Like many people have explained here already, I am also confident about people for using CBDC right now must be the late adopter of bitcoin one day or other. We could expect them to be adopting bitcoin once they are realizing the difficulties of having centralized money against bitcoins. This must be one simple reason why I am always in favor about that all government cryptocurrencies are indirect promotion for adopting bitcoins.
