From a Lawtimes report dated December 21, 2017.
"Some worry that excessive cryptocurrency trading will bring down the existing financial order, but most experts take the view that cryptocurrency cannot replace existing currencies such as the won or the dollar, or erode existing financial markets.
Attorney Jaesun Yoon (33, 40th class) of Law Firm Changchun said: 'Bitcoin and the like are currently no more than one investment vehicle and will not be able to replace existing currencies,' adding, 'A currency draws its force from being backed by someone with public credibility, such as a government. Today's cryptocurrencies not only lack that backing but also fall short on transactional stability, so they will not threaten existing financial markets.'"
