when USD does finally collapse, i think gold and silver are going to be the interim global reserve currency while all the powerful nations duke it out for top dog.

when the dust finally settles on that, i think Bitcoin is going to be the de facto global reserve currency in order to economically reunite the world.

physical assets will be a necessary transition for those who can't fathom Bitcoin not being pegged to a USD$ amount. but unless a massive EMP event happens, we will need a digital standard, and it's hard to see the digital yuan or any CBDC ever succeeding in that way (unless through sheer military enforcement).
