This kind of charities in most cases have the same intentions. I believe that charities that are accepting the BTC probably have false intentions that they are using for obtaining the decentralized coin for themselves. Poor people are just a mask behind which they are hiding their intentions.
What is wrong with USD EURO? Why ain't are they requesting the FIAT?
It is because the transactions in BTC cannot be traceable to the final users and because of that I personally don't support the charities marketing and advertising themselves with the BTC payment.
