I have a few friends in Nigeria and indeed, it's not just Bitcoin that is being used. In fact, the situation in Nigeria right now is this: everything but eNaira or Naira.

This obviously implies that Nigerians are also buying Shitcoins. As long as it is not a currency manipulated by their government, they prefer to put their money in it before it is too late.

But little by little they will come to Bitcoin exclusively.
