They don't have to use Bitcoin too often but only use Bitcoin for their saving. They shifted their money into Bitcoin instead of fiat savings especially for those who know Bitcoin potential in the future. They will search for how they can maximize their potential to earn more money to buy Bitcoin and not use Bitcoin in the daily expenses.
I think, it will help people living in such geographic area to grow financially and materially when they release bitcoin they have saved for years to earn good income. Until they have the knowledge of bitcoin before such people will have the idea, of how to shift their traditional money into bitcoin because they know what they are going to earn when they endure in long term holding, and it will definitely create an opportunity for them to maximize income in the future, People in that situation must be ready to take a risk on how to invest in bitcoin what they can afford to lose in bitcoin, before embark on bitcoin investment.
