Good point. Bitcoin and other crypto currencies is awesome for poorer countries AND poor people in rich countries. Unfortunately a lot of poor people also lack education and understanding. A lot of poor people in my own country could use their time here on Steemit, and learn how to make money on the BlockChain. I don't think a lot of them are though. They are preoccupied with tv-shows and Facebook/snap/insta.
But we need patience. It will eventually grow large enough for the masses to adapt and adopt.
