Little late for them now, considering they can only withdraw 60 Euro/day.
it's not like everyone there is poor now, i'm sure some rich guy are investing in bitcoin with their "money under their pillow" in case the situation will be more critical
They are interested with Bitcoin mining, a bunch of new miners will born.... 
i believe they know that it isn't profitable, at best they could go with altocin mining, or build their own altcoin
Why would the people with euros under the pillow invest in bitcoin? The euros are just as good as they where a month ago and will be good next month. The greeks problem is not lack of money or worthless money but problem with sirculation of the moneys. Bitcoin would not help them at all.
Totally agree with that. If you have cash in Euros on you, just keep it. No point gambling it for Bitcoins. If, however they will go back to Drachmas, it will devalue immediately as the government will need to inflate it by issuing new money to repay debts and pay people. Then it might be worth to change into Bitcoins to retain some value and avoid -at least initial/sudden- inflation and loss of value. Tough situation anyway.
