Yes where I live we price Bitcoin in dollars, though there is how they really calculate it; first of all of you’re selling it P2P they will ask you how much the coins you’re selling is worth in dollars, and let’s say for example the coins are worth $100, they will then tell you how much they are buying or selling in dollars per our currency, and if you agree to the rate per dollar, then they will do business with you. That’s how it works.

I don’t know how you put it your own country, but that’s how we do it here, we don’t price with any other currencies. And as for what you have said about fiat crashing in future, I don’t think anything as such will happen to the extent that fiats will stop existing.
