Philippines countries began to adopt cryptocurrency and in the African part of Africa have also begun to adopt cryptocurrency but what is needed to be able to increase prices is not only adopting but developing cryptocurrency technology in order to be more useful.
Actually the country of the philippines is not a strict country when compare to other asian countries , thats why the government is open to new ideas or technology and one example is the adoption of cryptos .
Now there are now merchants that accepts crypto payments and there were now also bitcoin atm's on some popular spots .
Since you also mentioned africa , what i know is that africa is a poor country and cryptocurrency wont really become a hit if ever their government will accept it .
