It is not about solving country wide problems, rather helping individuals have a currency they can trust to store value. If your life savings go to the drain because of inflation or other factors that is a highly desirable option to have. Also, most countries with currency issues usually accept the dollar for commerce whenever they can, if not forbidden, since it is a lot more reliable than their local option.
Sure, but again, no cryptocurrency can do that. The last thing people in Venezuela need is a payment method that takes 20 minutes to process, caps at 7 tx/s, and can't handle a refund or chargeback. What they really need is a basic monetary policy.
If the actual, genuine goal is to solve the problem of lack of viable currency in these nations, then the best solution is to solve the cause, not the symptom. Right now your goal is trying to find a nail for a hammer that doesn't have any, and you're trying to shoehorn vaporware onto a symptom when that's not what the people really need.
