Many governments attempt to force their populations to keep their savings in the nation's currency, while aggressively devaluing the currency. The richer people in those countries tend to try to get out of it via other currency holdings in offshore accounts or real estate, but the poorer set don't generally have that option. The ability to opt out of that in a way that's harder to confiscate than eg physical gold/USD is very helpful to those people.
