I'm studying this stuff and I seen the same article. All the investors I know moved assets out of the Euro years ago, when trouble started. As an individual, I'd say sit tight. The news changes weekly. Mind you, I would be concerned if Spain/Italy asks for a bailout (both of which are rumoured now, that they are on the brink of asking for it). Then civil unrest is quite possible. Banks will be one problem; no money in the ATMs.
Also, I'm not sure if that's the best date for the birth of the Euro, it might be. The other was before it was in our hands, the markets were trading in it a year or two before. I had a look at some country charts last night and found multiple dates in circulation for different countries, I gave up, just ridiculous.
