The future of Bitcoin starts with the poorer countries in my opinion. Many people in cities now in Africa, as an example, have smartphones; yet they still rely on their national currencies or the US dollar, and these national curencies are plagued by high inflation and corrupt governments.
Mexicans who come to work here, in Canada, right now still rely on Western Union to send their hard earned money back home, and get exploited with very high fees that eat into their gains.
I realize people from developing countries are slow to adopt Bitcoin, but it is them who stand to gain most by adopting it first...
