Spreading crypto currency to 3rd world countries

Am Raymond from an East African country Uganda. Most people dont know crypto currency and dont even understand how it works. Every when i even try to explain to my family and friends about it they wont understand and some people call it fantasy. But i want to make an effort to explain to people in my country and most especially third world countries that Crypto currency is the next future currency and that we should embrass it as early as possible.
