I am couldn't agree more with you but in my point of view bitcoin helps the one who live in poor country not directed help into a poor country. The financial level of the one who not rich will be higher if they "playing" bitcoin. Because there is so mamy ways to looking for bitcoin for free and get decent worth of bitcoin.
I think if that happens whole of citizens in a poor country, I believe bitcoin will slowly and indirectly helps a poor country from inside.
Yes, everyone can use the bitcoin if they have internet/pc or an smart phone but I saw a mistake that everyone commit here, people say bitcoin is opportunity however isn't, bitcoin is just an currency, we can see the same opportunities with fiats, like writting for a blog, doing some photoshop freelance and jobs like that, maybe you just can't find faucets/sig campaigns that pay you in fiat currencies and well, this is nothing if we talk about change the world.
