Nobody really knows if the Euro will or will not colapse
Anyone who says they know how this will end is deluding themselves
If anything is certain about this crisis, it is that nothing is certain. A big bank could suddenly fail. A government could fall, or announce a surprise referendum. Governments or central banks could conjure up a plan that might, just might restore calm (as in 2008). The economic data could turn out much better, or much worse, than expected. Public protests could explode - demanding exit from the euro, or demanding a democratically elected government in Brussels. Leaders could resign or be removed. Everything could be overshadowed by a crisis in an entirely different part of the globe (Russia? China? Iran?). Making predictions is a fool's game.
