Some Euro countries (Greece) might be on the verge of implosion, but there's no way the general currency could suffer any significant damage and Germany is the very reason for that.
The German economy is among the most powerful in the world and quite frankly you're more likely to experience an economic collapse in the US than in Germany. (Albeit that's pretty unlikely too, obviously. At least for now.)
The Euro collapsing is an apocalyptic scenario that requires quite a lot of things to go wrong. Much more than just Greece.
Germany has itself in the Euro trap just as strongly as the PIIGS. If they go under, how will Germany keep its currency down and where will it export to?
We're in the process of experiencing an economic collapse in the USA, and in Europe right now, and have been since 2008. The thing is, these things start small and people don't understand them until they are well underway... just as people didn't think there was going to be a problem in 2008 back in 2001 when the cause of the collapse started.
