According to monitoring by Hyperinsight, during the continued pullback of BTC from its peak last night, the whale on Hyperliquid with address 0xc6c chose to go against the trend, going long on 109.7 BTC with 35x leverage, amounting to 8.8 million USD, at an average price of 82,000 USD, with a liquidation line at 80,650 USD.This morning, the downward trend of BTC continued, and the price briefly hovered near the liquidation line, with a price difference of less than 50 USD (about 0.06%). The whale may have given up on closing the position for the first time as most of the funds were already lost on paper. Later in the afternoon, BTC rebounded to around 81,680 USD, significantly recovering on paper, and the unrealized loss narrowed. However, the whale chose to remain inactive again. Ultimately, in the past 10 minutes, BTC faced a large-scale liquidation during a second drop, and then manually stopped out before the next round of liquidation, with the account balance dropping below 100,000 USD.

GoPlus Chinese community analyzes the principle of the attack on the decentralized options protocol Ribbon Finance in a social media post.The attacker upgraded the price oracle contract to a malicious implementation contract through the address 0x657CDE, and then set the expiration time of four tokens: stETH, Aave, PAXG, and LINK to December 12, 2025, 16:00:00 (UTC+8) and manipulated the expiration prices, profiting from the exploitation of the erroneous prices.It is noteworthy that when the project party's contract was created, the _transferOwnership status value of the attack address had already been set to true, allowing it to pass the contract security checks. Analysis shows that this attack address was likely one of the project party's management addresses, which was later controlled by hackers through social engineering attacks and other means to carry out this attack.

ChainCatcher news, SMBC Nikko Securities Chief Economist Joseph Lavorgna wrote that recent inflation and labor cost data have raised questions about the wisdom of the Federal Reserve's interest rate cut today.He pointed out that the data released today showed that unit labor costs increased by 3.4% over the past four quarters ending in September, while the core services inflation rate in the third quarter rose by 4.4% year-on-year, well above the Federal Reserve's overall inflation target of 2%. "This makes us wonder why the Federal Reserve is so bold in cutting rates this month," Lavorgna wrote. "Isn't it more prudent to wait and see how the labor market evolves after the hurricane and the Boeing workers' strike? What harm would there be in waiting for clearer data before making a rate cut at next month's meeting?" (Jin Shi)
