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.
