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
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.
Don't just give him bitcoin but also try to make him understand what bitcoin is and what is the use of it for sure he will be curious to know then dig dipper information about bitcoin since if you just give it to them they will just sell it off and buy the amount what they get some certain goods for temporary survival.
