It is interesting that the Trump Admin is recognising the inherent problems for the US in being the world's reserve currency. It is trying to ameliorate the negatives while retaining reserve currency status by allowing lots of USD stablecoins.
I think this is only a partial fix and a stepping stone and the US itself will realise that BTC is the best global reserve currency. But the US needs to be a major player in BTC mining and nodes and needs a big BTC strategic reserve before this is allowed.
