Greek here. TEMS was a goddamn fail from the beginning. It was created by people who don't understand how economy works for their town. I don't know if it spread all over Greece, I never saw anyone in Athens even mentioning it.

On the other hand, most Greeks are helpless about technology. The younger generation believes that since Facebook exists, there is no reason for the rest of the Web. The older generation thinks that the whole Internet is a creation by pedophiles to rape more children. Now, imagine taking those two groups and telling them to use some "virtual money". They won't even let you finish your sentence. The older generation will immediately think of Bitcoins as the creation of Satanic Merkel and Barroso, while the younger ones are going to ask if you can win Facebook Credits from it.

Most Greeks can't see the Euro as a sinking boat; they see it as an easily repairable machine. Screw that.
