lol is that real? if it is then he must have wanted for the world to see that picture. maybe he's sending a message to the world, something like "get the hell off of fiat!" 
It's him, i know him irl and i'm sure he did it on purpose
What purpose? introducing Bitcoin to the world?
I think it's a nice idea
the purpose of making people from greece aware that they can exchange their worthless fiat currency for bitcoins. that's how they can get rid of their crappy government and their system.
