I believe knowledge is power and this also applies to any ventured investment. Understanding one's indigenous environment first can help to establish and harness strategies on how to dispense information about bitcoin especially on the country economic stronghold amidst exploring the vastness of trade and building currency value. Finally, creating more platforms like this and involving the indigenous media with the true value that bitcoin as a crypto portrays will be of great economic help to the community and the nation at large.
Your idea is right but doing so is not an easy task. I think, before we even introduce crypto to indigenous people, we must first solve their primary problems. Lack of access to primary needs such as water, electricity and internet should be the first things to consider. Then jobs and education are what's next, people from these parts are having difficulties in finding opportunities around them because they're location are mostly remote areas and opportunities are there in the cities, which are crowded in third world countries.
After all that's been said, only then we can start to educate them regarding investments, where cryptocurrency could be one.
