Well i got a different theory:
They are well aware about Bitcoin and the Movement happening atm. They are affraid.
Chancellor Merz announcing 1.7 Billion "special funds" at the beginning of the current tyranny is just one of the aspects to watch out for, and all the other "fundings" of ukrain yadda yadda. They know exactly how fiat works, and they dont want Weimar again.
As this happens... people would wake up and rebell. So, you destroy the current Fiat, but only enough to offer the perfect solution to your own "mistake"... called CBDC
They want to reset the game on their own terms
