A lack of clarity in South Korea's plans to regulate cryptocurrencies may be of concern, but experts continued to sound upbeat about developments in the space. In the latest twist in an ongoing saga, South Korea reportedly intends to make cryptocurrency operators exchange user data with banks, local media said on Sunday, citing a single unnamed government official. The plan, which will be a "measure of tax enforcement," is expected to come into effect toward the end of January or at the beginning of February, Yonhap News Agency reported. A separate Yonhap report on Monday said the government would impose a tax rate not exceeding 24.2 percent on cryptocurrency exchange incomes this year. "Korea Financial Intelligence Unit announced that financial companies are in the process of drawing up a guideline to prevent cryptocurrency-related money laundering, although any specific measures are yet to be confirmed," the Financial Services Commission said in a statement in response to the news. "The financial authorities have not looked into any measure to monitor cryptocurrency users' transaction data," it added.

The South Korean government faced an outcry earlier this month after it said it would prepare a bill to ban cryptocurrency exchanges, although it subsequently qualified those remarks, adding that more consultation would be done before a decision was made. An online petition on the presidential office's website against "unjustifiable regulations" in the space garnered more than 220,000 e-signatures as of Jan. 22. According to Pavel Bains, CEO and co-founder of decentralized database services start-up Bluzelle, the "mixed messages" were concerning to the company's South Korean business partner, blockchain accelerator Hashed. But he added that a bigger problem was the lack of education among the "new people" coming into the market, which could result in the spread of scams or frauds.
