Africa? No. Africa doesn't have a good track record at adopting advances in technology or culture.
Peru and other South American countries? I think that it is quite possible, but I think that a dose of pessimism is warranted.
There are three technologically and socially advanced countries that have high levels of inflation. They are: The US, the UK, and Japan. So these are the three countries where I expect Bitcoin to flourish.
Times are changing. Tons of initiatives are bringing the internet to new users everyday, and mobile adoption continues to skyrocket in poor countries. Countries that have seen huge percentages of their GDP erased every year by predatory banking and money transmitting fees will not stand for this forever. So Africa? Yes. Peru, Central, and South America as well. The Philippines could be a potentially huge market with about half of their GDP coming from remittances.
