Can Bitcoin or any other altcoin help poor countries?
how? what can be done?
Well Bitcoin is not created for really poor countries where the basic requirements are lacking, since bitcoin requires knowledge of computer and having access to computer and internet in a really poor country does not seem possible. Even if they get access to bitcoins where will they spend it?
Why do most people here assume that one needs a PC to use bitcoin?
I'm using bitcoin, making all transactions and work using my smartphone (except mining, obviously). I'm just using PC for some bitcoin related jobs like CoinTasker, writing on Bitcointalk.org or Trading. And Believe me, a lot of poor people in my country are buying Smartphones to surf the internet and discover the world of technology (Although, they don't even have something to eat!). So, in my opinion, I think they only lack the knowledge of knowing what bitcoin is.
When it comes to bitcoin reputation in my country, I can say that it's living in oblivion (something that I'm really grateful for, at the moment because our government is bloody stupid). So you are right. Even if the poor obtained the knowledge and basic requirements of bitcoin, they won't be able to spend it.
