It may have felt right, but by tomorrow it will be inaccurate, since BTC/USD will have continued to shoot up.
There really is no country-independent way yo express price, even those with the same currency have different prices for the same basket of goods based on a myriad of conditions. That's what Happy Meals don't cost the same everywhere.
Something like BTC, however, just seems convenient. In a thread yesterday, I needed to express the price of tools in a country-independent way. For giggles, I expressed it in BTC instead of USD; afterward, it felt right. A country-invariant store of value has real value on its own. It might not be BTC, but I don't think cryptocurrency is going away.
