The Greece default story has been widely spread and understood globally and along with those stories, the tales of bitcoin were also supposed to be talked about, by a lot of people about how 'it could' save Greece from its eurozone tragedy. Sadly, nobody can save Greece. Regardless of that, the media talked about bitcoin and it got attention globally, on an appropriate scale.
Yeah, it does indeed look quite bleak for Greece. If anything, the whole spike in interest regarding digital currencies is a look into what lies ahead in the future. Bitcoin may not be able to save Greece, but it could serve as damage control in dampening the effects of Greece's current financial troubles.
Yes, Bitcoin can be used as a band aid and shield against the collateral damage. However, making it the national currency will certainly screw things up for them because ts price value will multiply so much and that is exactly the fucking reason why euro failed for Greece, Greece can't afford that fancy shit man...
