Are you sure they also had such a plan? AFAIK, only El Salvador is planning to build something like that ^{[I did a quick search on Google, but had no luck in finding any connection to CAR]}.

I'm having mixed feelings about it... It was an awful decision to make it a legal tender when their internet penetration rate was ^{[and still is]} very low, but they could've tried improving the infrastructure to help with the transition ^{[as an outsider, I'm not seeing "any" improvement]}!
^{- I do know CAR is currently suffering from all sorts of angles, but when they overturn such decisions to go with the easy route of not dealing with the issue in question, it clearly shows the ones who are in control are just a bunch of fools!}
