A dual Euro currency is likely to work to save the Euro in the long run

I personally believe in neither the conviction of a single currency Europe nor the complete break up of the Euro - something in the between is likely to emerge sometime in the next couple of years and to last.
Some problematic and weak Euro members may exit the Euro, but the majority may stay.
It is possible that instead of a single euro currency in the euro zone there might be 2 currencies, that is, a dual currency system to provide some flexibility.
At the same time, they may establish some mechanism that allows a common euro bond, but allow limited internal risk sharing and fiscal transfer, but each country will still be responsible for their own actions.
