I have always come across people giving stories to promote bitcoin or give awareness of bitcoin in rural areas. It is a very nice job to tell people about bitcoin because it is the major currency in the world. In this rural area how can bitcoin be used when majority of people in the the town are battling with poverty, and how can bitcoin be used when majority don't have access to Internet. I think people in rural area needs to be financially stable first before knowing bitcoin.
I understand your point and I guess this is one of those limitations that cryptocurrencies have to suffer. The existence of the latter entirely depends on an electronic device/technology in which everyone does not have the privilege to own one. But I guess you can liken this in dreaming your favorite thing- you dreamt of having a beautiful house, so you aim to earn money and buy it.
The same concept applies in BTC- when a person aims to earn such, then that determination will fuel his urge to purchase at least a mobile device in order to transact and use BTC. But then again, it is more than just usage since the real effect is the awareness that people discover when they found out about the existence of BTC.
