That was a very smart move made by both the finishing end parties. It will be really helpful for the Greece citizens which are powered by the bitcoin currency. It will also be a nice way to show off how decentralised crypto currency is much better than the ordinary and how it is benefiting the society real time.
I don't think a bitcoin ATM will do most people in Greece any good because they can't even get more than 60 euros out a day I think. Maybe some will start putting that money into bitcoin but I still think doing that would be risky.
