ES and Argentina adoption of a foreign currency followed the failure of their respective local currencies. I suspect that the decision to switch to the usd makes sense because the US are their biggest trading partner? In a way, it's actually a similar situation with France and their former African colonies, no?

I was initially very hopeful the Central African Republic would follow ES steps, but it became clear very early that they were actually setting up a gigantic scam. Our next best shot at adopting bitcoin will be the deployment of the strike wallet.

I don't understand your reference to Liberia in this context...
