Binance CEO Changpeng Zhao (CZ) clarified that the Bitcoin sell-off on October 10, 2025, was primarily due to macroeconomic factors, specifically tariff-related news, rather than any failures within Binance's systems. During a Binance Square AMA on January 31, 2026, CZ emphasized that Bitcoin's vast market scale makes it difficult for any single entity to manipulate prices through large sell-offs. Binance's post-incident review identified two technical irregularities on the day of the crash, including issues with transfers and UI display, as well as certain index deviations. However, CZ denied these were responsible for the market downturn. OKX's founder also noted that the design, risk controls, and infrastructure of major platforms could exacerbate risks during volatile market conditions.
