The major challenges, which are limiting the Bitcoin adoption among the third world countries, are internet connection and smartphone accessibility.

In Africa, for instance,

According to various sources from across the web, the estimated number of internet users worldwide is 5.3 billion

570 million internet users in Africa (about 38% of the continent's population)

5 million internet users in Malawi (about 24% of the country's population)

Since Bitcoin is the native currency of the internet, people need to have internet access in order to use it. How about the majority of the people who don't have any access to the internet? How can Bitcoin adoption be achieved among the people without internet connection or smartphone?

One of the viable solutions for the challenges to Bitcoin adoption among the third world countries, is promoting projects like Machankura, which enables anyone in Africa to access Bitcoin via USSD technology, without the need of the internet connection or smartphone possession. Machankura is currently working in 9 African countries, and aims to onboard members of all African countries onto the Bitcoin Standard. I wonder if there any other projects like Machankura in the other regions?
