Please explained how. Where will those poor people in that poor country will get money just to start properly the mining method to make bitcoins? The amount needed to start mining is not a joke.
Do you think people in that poor country will give priority to that?
That's right, a poor country would probably have poor people living in it and mining is not a joke, one mining equipment costs a lot of dollars which is not something anyone can pay and poor countries would probably not be able to fill that cost, they would rather try other free methods for earning bitcoins which might help them somehow to accumulate some bucks every month.
Well of course they can't mine. but they can do faucets, and after faucets they can start trading, so with trading they could earn more money, means country would be richier
