If it was so easy to make a living with bitcoin, with all the time years that it has existed, then there would not be any poverty. Because being poor drives people to try anything and everything to try and earn even a penny to live.
But, even after then the poverty will remain on that regions where their governments can not manage to provide them any internet connections and to those who cannot afford a internet connection to take start with.
Not only that, there are household who can't even afford to buy the cheapest computer as their budget is just enough for the food budget.. but really if the government love its people, they must do something to have a free internet and computer so those who don't have job can try online jobs while they are still looking for a day job...
Well some budget of a country are for health care and for defenses,they hard care for people who work for the below minimum salary.
All the government want is to get money as much as possible,only a few once can earn a living through bitcoin.
