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.
Indeed, Bitcoin is not a panacea, it is not a magic wand, it is simply a currency, we cannot just rely on it and think that it can improve people's lives or a country's economy. It is confusing that many people are investing in bitcoin and they can't even improve their own economy significantly but they can exaggerate and come up with unrealistic ideas with bitcoin.
You are right, to improve people's lives, there needs to be help and support from the government by creating more jobs, reducing taxes, building infrastructure...there are hundreds of factors that need to be done to improve people's lives. Also, people need to put more effort into life, don't just rely on 1 speculative asset and think it can save us even if we are lazy.
