Illiteracy is the cause of poverty. We know a cup of coffee (Starbucks) = 20 notebooks, or a school bag, or two pairs of slippers for poor children in Vietnam.
bitcoin has so many potential in terms of improving one's economic status, may he be rich or not, illiterate or not, maybe not directly can help, because cryptos are only intended for digital use unless it was converted thru exchange sites, what bitcoin can do is to gather anonymous donations to non-government agancies that caters the poor. maybe some bitcoin users with a big heart can convert their bitcoin and donate it to some institution. there are some sites that accept bitcoin donations though, like bitgive.com
