Richard Werner is a professor emeritus of international finance at the University of Southampton. He is a critic of bitcoin, and has argued that it is a bubble that is likely to collapse. He has also argued that bitcoin is not a currency, but rather a speculative asset.

Werner has cited a number of reasons for his skepticism of bitcoin. First, he argues that bitcoin is not backed by any real assets, and that its value is therefore entirely based on speculation. Second, he argues that bitcoin is too volatile to be used as a currency, and that it is therefore not a viable alternative to fiat currencies. Third, he argues that bitcoin is a breeding ground for criminal activity, and that it is therefore a threat to the stability of the global financial system.

Werner's criticism of bitcoin has been echoed by a number of other economists and financial experts. However, there are also a number of people who believe that bitcoin has the potential to revolutionize the global financial system. Only time will tell whether bitcoin will ultimately succeed or fail.

In a 2018 interview with Bloomberg, Werner said that bitcoin is "a Ponzi scheme" and that it is "only a matter of time before it collapses." He also said that bitcoin is "a threat to the stability of the global financial system."

Werner's comments were met with mixed reactions. Some people agreed with his assessment, while others argued that he was being too harsh. However, there is no doubt that Werner is a respected economist, and his opinion on bitcoin is worth considering.
