The euro has proved a huge success since its introduction as a virtual currency 10 years ago. Without the euro, a number of European countries would today find themsleves completely at the mercy of the international finance world. The European Central Bank can be proud, with the euro having become one of the most stable currencies in the world since its launch 10 years ago. It is now being seen as an anchor to cling on to in these stormy times, and some EU members currently outside the euro-zone such as Hungary or Poland are desperate to adopt the currency without delay. The EU is saying they should not take entry for granted, however. Dagmar Zindel reports from the European Central Bank in Frankfurt and from Budapest.
