Bitcoin can help poor countries, because it helps actually their people to get some income online easily. I know many friends from poor countries making a living from earning Bitcoin online ,and it's can increase a new job for poor country ,that job can do by following campaign.
But there are some poor countries where even the government is unable to provide internet connection to its citizens that is a big problem for the people for that issue if some bigger companies start to provide a network of internet to that nation in donation then they will be able to learn about bitcoin and will be a help to them from bitcoin.
