Bitcoin isn't the cure all solution for stability in rural areas in my opinion, there's a lot of factors that are needed to be done to consider a possibility in stability in said area with one of them being the government helping the areas that need help in terms of modernization, building roads and encouraging businesses and investors to have their business on those areas are a very big help to those rural areas more than bitcoin could ever do. Look at it this way, they know much about bitcoin but there's not really a lot of places or institutions where these people can use it plus I think that bitcoin is best utilized when paired with modernization programs because it involves technology and it doesn't really work well when that's not going to be the case.
