Bitcoin have been seen as another way to up lift the poor but the truth is that things are not done that way and problem now is that even if you want to invest one of the key things that is needed is funds because from another view the high the funds invested the bigger the profit and this is why a lot of people that have money keep making money because they have enough money so this one of the reason why the rich keep getting rich.
Bitcoin won't change someone's standard of living.
It will only help to have an alternative to what's already there and to steadily accumulate it to have more boons to come.
A poor country cannot and should not invest in Bitcoin. There are basic things to look into that will stand as the major source of revenue for the country and Bitcoin isn't that investment. Bitcoin investment can only add to the list of investments, but not a major investment to make the economy of that country better. When trying to move a poor country into a developed class, you don't depend on one investment only, there are many sectors to look into and it should first go through what the country has to offer to other countries, natural resources included but a country that will only depend on it's natural resources alone to work the economy will some day have to change that perspective.
