According to Prof. Volker Wieland, private digital currencies will be widely used as a means of payment in the future. However, he sees the cryptocurrency Bitcoin more as a "speculation object" than as a practicable currency due to the enormous price fluctuations, as he explained in an interview with the "Frankfurter Allgemeine Zeitung".
Cost advantages favored the upheaval, Wieland continued. "Paying digitally is on the rise, and at the same time there are still high transaction costs with traditional means of payment." However, the change is taking place more slowly than many expected.
