Great news, Binance keeps surprising us. They already did help china with all sorts of medical supplies, in January, and they have been distributed to several hospitals. This initiative, also, will mostly go to countries with the highest numbers of infected people but honestly, someone should think of third world countries, they are the real ones who will suffer tremendous damages if their citizens don't abide by the general lockdown policy because they don't have strong means to confront the virus.
I think the most important thing stopping peoples from giving charity is the lack of confidence in how their money will be distributed and their fear that the process get corrupted. Blockchain provide the best solution for such problems since all transaction can be publically published.
