My country has called digital assets a matter of freedom of expression, so unless there's a high bar of "harm" to cross before they can be banned. The tax laws around them are a bit onerous and I'm still working through it all.
I think CBDCs are a bigger issue for trade currencies like the USD, Pound and Euro. Already developed small countries can wait and see. Large or countries with a underdeveloped financial sector might act sooner too.
