Indeed everyone holds non-local currency too. I'd presume USD and/or EUR have taken on the role of "store of value". I lived through collapse of a state 30yrs ago, and exactly that happens: locals refuse to hold the local currency (that reflecting on the health of the state is quickly losing value), there is a vigorous fx exchange market (either white-legal, grey-tolerated, or black-illegal but existing), and locals exchange their savings from local to foreign fiat currency. No one ever used gold, not once I saw gold being used for anything. Nor any other commodity. Foreign fiat currency that is stable is much more practical and convenient. Until BTC is as convenient as a credit card, can't see it used as "means of exchange". As store of value - maybe, but foreign currency maybe again more stable less risky (on humant time horizons), so again wins for that too over BTC. Sorry for the spoiler.
