The problem is always broke down to just a few issues for Countries like this.
They lack internet connection or they lack places to buy/sell bitcoin in a manner that would replace the current set up. Cell phones seem to be the only way to get around both those issues but do not know how you can create a internet network this way.
The problem is poor countries are poor, as in average person living on less than $1.50 US a day. It doesn't matter what you use for money -- poor is poor.
Yes but in some parts of Africa they use mobile credits/minutes in exchange as cash,so bitcoin can be used in the same manner. Cell phones are cheaper in these areas and just need to tap into the internet which Zuckerberg is trying to do with balloons I believe,but I do not trust his end game for this.
Poor people still transact but they need to know the system is reliable and bitcoins fluctuations might not help things.
