People often talk about the price potential of BTC or gold, in terms of US dollars or euro. In my opinion this does not make sense because the value of euros and dollars can be destroyed by central banks printing them to infinity.
It's because that's been the standard of conversion for gold and bitcoin. The value of these currencies might go lower but I doubt it that they will entirely go to zero and utterly be destroyed. There can be changes in terms of monetary system but these two that you've mentioned can't just be gone too quickly just as we say.
Even with current news about BRICS that's trying to de-dollarized with their economies. It's gonna to be a work in progress and won't be just applied too quickly so as usd/btc, usd/gold, eu/btc, and eu/gold.
Also with their ability to print unlimitedly, they can still do such controls with it through interest rates and just like what US did recently and still doing some of its control based on how they want to value its fiat.
