The South Korean government said Monday it will collect up to 24.2% of corporate and local income taxes from the country's digital currency exchanges this year, according to an English-language report from the local Yonhap News Agency. In a potential move towards taxing cryptocurrency transactions, the news agency also said the government plans to require digital currency exchanges to share users' transaction data with banks.
Bitcoin trading in South Korean won accounted for 4% of trading volume, according to CryptoCompare. The Japanese Yen had the largest share, accounting for about 37%, while the U.S. dollar had about 33% of bitcoin trading volume, the website showed.
Nearly all digital currencies plunged in the middle of last week following concerns over increased cryptocurrency regulation in South Korea and China. Bitcoin even fell below the $10,000 level that it first topped in late November.
Last Tuesday, Yonhap News reported that South Korean Finance Minister Kim Dong-yeon also said in a radio program interview that "the shutdown of virtual currency exchanges is still one of the options" the government has. The news followed an announcement in late December the South Korean government is banning new trading accounts, and requiring users to use their real names.
However, prices had stabilized by the end of last week.
Fundstrat's Tom Lee, a noted Wall Street strategist, raised his price target on bitcoin Thursday and now sees the digital currency hitting $25,000 by the end of this year. Lee also said that $9,000 is low for bitcoin and offers a buying opportunity.
Reuters reported Monday morning that new research from accounting giant Ernst & Young found that more than 10% of funds raised through "initial coin offerings" are lost or stolen in hacker attacks.
