Will bitcoiners be the beneficiaries of the Cantillon Effect if central banks adopt bitcoin as a reserve asset?

It just occurred to me that if central banks print money to buy bitcoin, even if its not publicly known, inflation of all money relative to bitcoin will be extreme. This will be seen as a volatile movement or institutional adoption. Then, when it is made public there will be a run to buy more bitcoin.

This might have been covered in a book. But this leads me to believe hyperbitcoinization will be very dramatic. Is there a case where central banks dont print money to buy bitcoin?
