Bitcoin or any other altcoin cannot necessarily help poor countries. Not everyone in third world countries has an Internet access, and even if somebody has an Internet access, it doesn't assure that he is interested or is he knowledgeable about Bitcoin. I think the only people that can financially helped by Bitcoin are those that have a deep knowledge about it. The trading, gambling, and other stuffs that you can do with Bitcoin can only be obtained through experience and an intrinsic interest towards Bitcoin.
