Cryptocurrencies issued by central banks, known as Central Bank Digital Currencies (CBDCs) can potentially have a negative impact on the South Korean financial system by undermining commercial banks, according to a recent report.

As covered, a survey revealed top Chinese economists are divided on whether the country should have a CBDC. Nouriel Roubini, one of the most well-known critics of blockchain tech and cryptocurrencies who teaches economics at New York University (NYU), has stated CBDCs will “destroy” bitcoin and other cryptos.

Last month, Yonhap adds, the Bank of Korea revealed it doesn’t plan on issuing a cryptocurrency in the near future, after conducting a study on it. It said, however, it’ll further look into the advantages of disadvantages of lau
