I don't know, but I doubt very much your numbers.
Argentines are currently fleeing their Peso and buying USD, Gold and Bitcoin.
Same in Venezuela and Zimbabwe and there's a growing interest in Iran.
There's some girls in Afghanistan that are depending on bitcoin.

Since 2014 a non-profit has been standing up internet/digital learning schools for girls.
They write blogs i guess and get paid in bitcoin.
Bitcoin is good because girls have full control, they can't open bank accounts in Afghanistan, not without a male relative.
It's dangerous to have cash and often the cash they have gets taken from them by family.
