I believe the OP is not well-informed about the trend, this is no longer new, Switzerland is even late on the announcement and has nothing to do with true cryptocurrency. There are many countries planning the CBDC and are waiting for the implementation for the fear of it affecting businesses already in the payments sector.

To me, there is nothing any CBDC would do to keep your privacy as it's a centralised approach in which the government would be able to seize your assets both legally and illegally. No government would want to be out of the control of their creation, so it's better we don't expect anything intriguing from them.
