No, although bitcoin will be able to help some people on this country, but remember that in a poor country not everyone has access to internet and gadgets. People like in Africa are worried on how they would buy their food on a daily basis.
Also poor countries usually have a corrupt government. Regardless of what type of currency they would adopt as long as corruption is not stop they will still remain poor and living conditions will still remain the same.
Even if things are to change a little bit, that still will not stop the government from going ahead with their corrupt practices anyway and then still end up crumbling the whole economy of the nation.
