Do Chinese people have any other choice here? Lol. That's why their government build their own CBCD, so don't be surprised that maybe by the end of next year, billions of Chinese have one time or another uses their CBCD to do online transactions specially if they are going to interact with their government.
Just to be fair, bitcoin can be used to purchase things as well. And they are not even comparable to CBCD of any nations, or like in this example the Digital Yuan.
