Avaaz is a great voice and movement for change, I'm surprised they don't accept Bitcoin?https://secure.avaaz.org/en/petition/Avaazorg_Avaaz_should_accept_Bitcoin_donations/?oLobecb
Bitcoin and crypto currencies are the only neutral transparently auditable currencies and are not controlled by governments or corporate banking interests, transaction fees are lower so more funds go to the causes the get donated for. In fact Avaaz should be looking into creating its own Coin have a look at the new Crypto 2.0 platform like Counterparty https://www.counterparty.co
Bitcoin is the most effective way of gaining back power to the people and stopping oppressive governments or subversive corporate interests. See: - Bitcoin vs. Political Power: The Cryptocurrency Revolution - Stefan Molyneux at TNW Conference

The Blockchain will record history going forward and in so doing it will free society from its "chains". Viva the blockchain Viva! From the ashes rises the Phoenix.
