What are you currently using to trade if the currency doesn't have an international rate, can you still use it?
How much is food for example on average per person per month (or how much is a kilo of sugar, flour, potatoes (or equivelant)... Etc?
What's the priblem with not being able to convert? Does no one sell usd for it?
I'm curious about that also. Because it is hard to believe that they have no money exchange shops in their area.
Even their local fiat to USD? I don't think we are getting what the OP is saying here.
Because is it possible for a specific country, even if it is third world, that they can't exchange their fiat to other currencies?
