For bitcoin to be efficient there is a need for minimum technology for example pc and a good internet connection, this is the reason why bitcoin is not a solution for every country. I am sorry to say this.
You know that economic problems in a country are very complex, and even developed countries still have a lot of poor people and their economies sometimes go up and down, bitcoin can't make a country's economy stable, because a country's economic problems are not just unemployment, but many other things and more complex
Agree, a country's economy depends very much on different factors, that could be a government strategy, that could be a natural and environmental problem and condition, or it could be a problem of education, and a lot of different issues. And with so many problems, bitcoin really can't solve all, the condition for it to be beneficial for everyone is that they need, conditional to own the right equipment, and more, and with so many conditions, only very few individuals can change lives with bitcoin, which is something we see very clearly
