Have you heard about the huge of donations that flooded Philippines after the typhoon? Believe it or not. Many of the funds were missing and the places that has been devastated is still misserable. Even the donations has been taxed. I wonder if it's still the same scene if the donations was sent in bitcoin instead. We don't have any taxation laws for intangible goods yet.
I think the odds would be better as they could be received by organisers in the destination country instead of some western middleman scam charity.
