The Soviet Union had a similar problem. Because they had no internal economy for pricing, they would copy the price structures of Hong Kong and the US so they could do economic calculation.
In Japan, things are priced in Yen. In America, things are priced in Dollars. In India, Rupees etc etc.
No one is pricing in BTC. They are converting the local currency into BTC.
And no one is pricing in BTC because pricing something in a currency requires a decent amount of stability, right?
