I live in the Czech Republic, in the centre of Europe. The decimal system was adopted in our country (then it was Austria-Hungary) in 1857. Here we are all used to counting in grams and kilograms.
My country does not participate in the single currency project EURO. We have our own Czech crown. But we are such a small country and currency that our foreign trade is in Euros and Dollars.
There is quite a wide adoption of cryptocurrencies in my country. For example, precious metal coins can be bought with crypto.

I spent a lot of Fiat USD's in "Old Town" Prague 1... If you liked Fiat USD's, you're going to love our soon to be Announced U.S. Paper Coinage and Crypto Coinage...
I know your opinion of the change that is coming. The inhabitants of Prague hardly go to the Old Town. There's only a tourist rip-off industry there. 😀
That's where I bought my 1913 Five Dollar U.S. Gold Coin... I paid about 182 Fiat USD's and it's currently worth between 62,000 and 100,000 Fiat USD's... So, it paid for my entire trip and much more... So, I did good... I spotted it while I was Window Shopping...
Fortune favours the prepared. A trade like this happens several times in a lifetime. But you never know when. You have to be sensitive to your surroundings.
