Despite the possibility that nation-states will also start HODLing Bitcoin? El Salvador might only be the beginning. I believe when nation-states start to understand that they need to hedge, and HODL Bitcoin as protection against the possbility that they might lose control of the economic/financial system, they will hedge.
El Salvador are pioneer and more nations will join the party. I think those nations will be part of a strategic game in which we might see some loopholes that we can not imagine of at the moment.
Do you think that with Bitcoin, cryptocurrency or CBDCs, someday a nation can wipe out their national debt with one click, after one night, something like this. It would be a chaotic situation and we don't know how far it will go and how it will be solved.
