Meanwhile, anonymous accounts used in cryptocurrency trading will be banned in South Korea starting on Tuesday.

South Korea's financial regulators say the ban aims to stop virtual currencies from being used for money laundering and other crimes. The move follows stepped up efforts by South Korean authorities to temper South Koreans' obsession with cryptocurrencies. People ranging from housewives to college students and office workers have rushed to trade in the market despite intensive warnings about risks from global policymakers. The ban on anonymous trading had an immediate effect on the market, bringing bitcoin prices down 3 percent in South Korea's second largest trading platform.
