A South Korean cryptocurrency exchange has said hackers have stolen about one-third of the coins traded on its market, an announcement that sent bitcoin prices tumbling to a two-month low.
It did not give a value but Yonhap News agency cited unnamed industry sources saying coins worth about 40 billion won (USD 37 million) were lost.
If true, that would make it the biggest cryptocurrency theft reported to date in South Korea.
Bitcoin was trading at USD 6,780 yesterday, down from more than USD 7,500 before the weekend, according to Coindesk, which monitors prices.
Cryptocurrencies still are popular, especially with young investors.
