South Korea plans to grant financial regulatory agencies "emergency intervention rights" and is considering limiting the leverage multiples and investment amounts for single-stock leveraged ETFs

According to NATE, South Korea's financial regulatory authorities are advancing the revision of the Capital Markets Act, planning to grant regulators the "emergency intervention rights" to directly take market stabilization measures during periods of severe stock market fluctuations.Currently, the Financial Services Commission (FSC) of South Korea has initiated relevant legal amendments with the Financial Supervisory Service (FSS), focusing on single-stock leveraged ETF products that are believed to amplify volatility during the recent stock market crash. Proposed regulatory measures include adjusting leverage multiples and setting investment limits.In cases of abnormal market fluctuations, the aim is to reduce the risks associated with concentrated trading of funds. Additionally, South Korea's financial regulatory authorities are considering setting personal investment limits for single-stock leveraged ETFs, standardizing the investment cap at around 20% to prevent excessive concentration of funds, and introducing a simulated trading system to enhance investors' understanding of the risks associated with leveraged products.South Korean regulators stated that the increase in the basic margin is primarily aimed at raising the investment threshold, while the investment limit effectively sets an "upper limit" on fund inflows, with both measures forming a complementary risk control system.Previously, South Korea had raised the minimum margin requirement for investors in single-stock leveraged ETFs from 10 million won to 30 million won starting July 31.Data shows that on the first day of the new regulations, the trading volume of 16 related leveraged ETFs was approximately 3 trillion won, only about a quarter of the previous trading day's 12.4 trillion won, and a decrease of about 80% compared to the 15 trillion won level on July 29.

Galaxy Research Director: Coldcard attack investigation陷入 AI dilemma, forced to turn to Chinese open-source models to track stolen funds

Galaxy Research Research Director Alex Thorn stated that the attack targeting Coldcard wallet address generation is still ongoing. They are currently continuing to collect victim information and adding new victim addresses and attacker addresses to the investigation database.If users are still using affected Coldcard single-signature addresses, they should immediately migrate their funds. According to current investigation results, all single-signature Coldcard addresses generated after the firmware upgrade in March 2021 may ultimately be emptied by attackers; it is just a matter of time.According to Galaxy Research's analysis, the first three confirmed rounds of attacks exhibit highly programmatic characteristics, with similar attack transaction patterns. A large amount of stolen Bitcoin remains in the attackers' addresses and has not yet been transferred.At the same time, some new opportunistic attackers are emerging, transferring and laundering funds through methods such as stripping the funding chain, cross-chain services (like ThorChain), and overseas betting platforms.Additionally, Alex Thorn mentioned the limitations of AI tools in security investigations. Some large language models in the United States have restricted researchers' ability to track stolen funds, and the team has even had to turn to Chinese open-source AI models to assist in protecting user assets and conducting on-chain tracking.He finds this phenomenon "incredible" and plans to promote discussions on related issues at the government and industry levels. Alex Thorn concluded by stating that a large amount of stolen funds remains stagnant, and the team is continuously tracking relevant addresses, having shared information with relevant U.S. agencies and industry partners. He calls on the Bitcoin community to learn from this incident, strengthen self-custody security education, and raise awareness of wallet complexity.
