If I was over there I would be standing at ATMs and banks handing out pamphlets with bitcoin info on them and offering to sell bitcoins to people by putting my email address and QR code on the pamphlets. Of course, I would cash any Euros I got into BTC immediately to avoid the EU risk.
Looks like most people will be playing hot potato with the euro now. I wonder who's gonna end up having all these euros if people start converting them to other assets.
