In quotes by Financel Times Wiedmann says;

"My personal take on this is that central banks should strive to make existing payment systems more efficient and still faster than they already are – instant payment is the buzzword here. I’m pretty confident that this will reduce most citizens’ interest in digital currencies."

"Digital Currencies could worsen future financial crises, Wiedmann says"

"Allowing the public to hold claims on the central bank might make their liquid assets safer, because a central bank cannot become insolvent. This is a feature which will become relevant especially in times of crisis – when there will be a strong incentive for money holders to switch bank deposits into the official digital currency simply at the push of a button. But what might be a boon for savers in search of safety, might be a bane for banks, as this makes a bank run potentially even easier."

I think Wiedmann don't understand why we believe in crypto's. The main reasons for me to use cryptocurrency's are

• privacy
• speed
• too support great concept's which are possible due very small and quick transactions (SIA, Golem and much more concepts)
• and a lot of other reasons!

What are you're main reasons too use crypto's?
