I don't see the article explain how this works, or how it works in El Salvador. Are they establishing an official exchange rate between Bitcoin and their existing currencies? Or picking some market rate and letting it float?<p>If you have more than one official currency, people will pay their debts in whatever is cheaper. So I don't know how that's supposed to work.
CAR is already using a multinational currency, the CFA franc, which is used in about a dozen nations.<p>If they want additional currencies, then it's difficult to understand why they don't add the US dollar before Bitcoin.
