propagating Bitcoin amongst indigenous populations is a very difficult task indeed. The reason being, that it's hard when they do not have cell phones or smartphones to give them Bitcoin wallets. Also, there may be language barriers in dealing with such peoples. Therefore, much effort must be taken to ensure that they understand the blockchain technology.
Yes this is a difficult task, It is also possible to teach them step by step but it will take a long time to get started, Because from mobile phones (How to use it) and Bitcoin it really needs enough attention to be able to teach, And we know , that most Indigenous people do not finish school because they are far from the community, or may prefer to work to help the family.
So this is a challenge we must take!
I think that this is really a difficult task to educate people about the principles and features of cryptocurrency. I was already able to train 5-7 people, and then it was very difficult for me. I spent more than 8 months on this business.
