There's actual real fiat currencies for that. The USD, the EUR, the YEN, the CHF... plenty of choices that have been used for decades in the developing world. I'd much rather have my money in a stable-ish fiat currency like those than in some Bitcoin that goes up and down 10% at will or by Elon-tweet. In fact some countries, e.g. Kosovo and Montenegro, in the Balkans, use the euro as a de facto domestic currency since 2002, even though they have no agreements with the EU.
