Perhaps we should first find out how effective the China cbdc so far since it was launched then you can draw up some ideas what will happen in other countries if cbdc is introduced,
To me it will same as any other government owned project which is heavily centralise and control the people, however, if people are given the option to choose between cbdc and other crypto, many people won't bother about cbdc.
it's not up for the people to chose but the government. if the government of the country will have their cbdc, the people in this country will use cbdc obviously. you can only wish they allow crypto as well.
china will have the advantage to dominate in the future because they are the first to have a working cbdc but the country is the manufacturer of the world.
