Welcome We are anonymous we greet you on the lands of the original people of this country the Aboriginal elders and the Gadigal and Eora elders. Always was and always will be Aboriginal land. We are Operation Icarus. We have notice increased attack on Bitcoin and other crypto currencies while you continue with your Panama atrocities and legalised fraud .We are anonymous expect a response to this outrage against the people of this planet. 
‘Citizens of the world, we are seeing the biggest advancement in currency history. Financial empires of the world are starting to crumble against digital currency. This is what humanity needs not welfare cards that deminish our self esteem, we want a funky coin lifestyle, freedom of choice utilising peer to peer currency. Financial institutions and governments no longer will control our dealings as capitalism and communism are destroyed and our money is freed from fake scarcity economics that drive these cycles of boom and bust . The corruption outlined in the Panama Papers show that our leaders can not be trusted with our economic futures.
 We need to protect ourselves and each other from another wall street financial crisis and mismanagement by our corrupt political class that only wants what is good for their next employer which will be the very companies they are trying to control and have meetings with the Mafia. This is the answer a federal Independant Commission into Corruption and a Royal commission into the Banking sector and its entrenched trails of corrupt money. Your time has come and now you have to Expect Us Expect Us Expect Us you should of expected us i told you before didn't i to expect us now you have nowhere to run you cowards ...
