Vienna used the Austrian schilling as its currency in the past. But for two decades now, it has been using the Euro as its main currency thereby saying goodbye to tradition. This is after Austria joined the European Union (EU) in 1995 and the Eurozone in 1999.
With the introduction of the bitcoin, it is expected to give the city and the Austrian country in general another unique European experience. But the use of this new currency is not yet widespread and the Austrian government's position is still between indifference and hostility.
