It's true that even poor people don't necessarily understand cryptocurrencies, especially bitcoin,
and I don't think poor people will think that far, of course they will think for themselves how to survive,
so even though some give free bitcoins of course they don't understand what to do with bitcoins
I disagree.
If someone is poor, they're striving to survive but at same time they're hoping and dreaming of getting out of the poverty line someday. And it urges them to do extraordinary for their dreams and to get out of the rat race.
Try to give a poor guy bitcoin and for sure that he's going to do what it takes to understand it and what's the best thing to do it. Almost everybody got a signal for the internet to do simple search.
