What i like, there is no bright marketing, as i see people do it on there own enthusiasm, idea also is good not like lots of ICO's now, where people don't understand what they are doing. But , why for you using crypto for charity?
Crypto gives great opportunity , send funds in seconds , micro-transactions, for bank in regular way (VISA) there is impossible,to send 1-3$ or 10$, even if its same bank in the same country, fee will be more than donation. So there is no way people from other countries send 20$ or 5$.With crypto its possible.
