Yes, it would help people of poor countries a lot.People get very low wages in poor countries.If they start earning in bitcoins, it would become a big amount when converted in their local currencies.Mostly corrupt politicians and big corporates snatch earning opportunities from the poor. But in bitcoin, they can snatch nothing from the poor.Fair enough opportunities for poor to earn in Bitcoins.It would increase their standard of living to a great extent.
"They can earn Bitcoins so it will help poor countries" It's something I have seen being posted many times in this thread.
With earning Bitcoins most people refer to earning Bitcoins through signature campaigns, but what if they don't exist anymore at some point? How will these people then earn money?
Instead of mentioning signature campaigns, people should mention that skilled poor people can easily offer their services through the internet with Bitcoin as preferred currency.
And the poor people that don't have skills, or an internet connection, and very broken English, Bitcoin can't do anything for them.
Another thing, it are certain individuals that might experience the usefulness of Bitcoin, and not entire counties. That's impossible.
