On the evening of December 3, affected by the news of the martial law order issued by South Korean President Yoon Seok-yeol, the market of Upbit, a mainstream cryptocurrency trading platform in South Korea, experienced a flash crash, resulting in a serious negative premium for a large number of trading pairs. Among them, the price of BTC once fell below $70,000, and DOGE flash crashed by more than 50%. In addition, "zombie coins" such as XRP, HBAR, and XLM, which have risen rapidly in recent days, also experienced a huge retracement, and once again staged a "regional 312". Affected by the flash crash of Upbit, the crypto market also experienced an overall decline.

The huge negative premium also brings rare profit opportunities to arbitrage traders, and many traders with Korean KYC have entered the battlefield. However, according to feedback from some community members, Upbit's Korean main site has been down, but users can still conduct arbitrage transactions through other regional portals such as Indonesia. Upbit officials also issued a statement later saying that the website was interrupted due to a surge in trading volume.
