December 2nd, Anthropic's latest research shows that AI Agents possess significant on-chain attack capabilities: in a simulation test on truly exploited smart contracts from 2020 to 2025, Claude Opus 4.5, Sonnet 4.5, and GPT-5 together reproduced vulnerabilities worth approximately $4.6 million; while scanning 2849 contracts with no known vulnerabilities, the two models also discovered 2 entirely new zero-day vulnerabilities and successfully simulated profit.The research points out that the on-chain attack returns of AI have doubled approximately every 1.3 months over the past year, and it has already fully developed the autonomous, profitable vulnerability exploitation capability.

December 2nd, according to Miner Weekly, Bitcoin miners are currently facing the most challenging profit environment in history. The significant price drop of Bitcoin in November has led to a decline in mining revenue per unit of hash power from around $55/PH/s in the third quarter to around $35/PH/s, below the average all-in cost of major publicly traded mining rigs at $44/PH/s.With the network hash rate approaching 1.1 ZH/s, the cost per hash reflects the actual earnings under the current mining difficulty. Even with the latest mining rigs, the payback period exceeds 1000 days, much longer than the approximately 850 days before the next halving.

December 2nd: According to the latest data from F2Pool, with the network difficulty remaining high and electricity cost estimated at $0.06 per kWh, several older models of Bitcoin miners have fallen below their shutdown price and entered a state of unprofitability. Models such as Antminer S19, S19j, S19 Pro, S17 series, Avalon A12/A13 series, and Whatsminer M20/M30 series have their shutdown price mostly around $90,000 to $100,000 or even higher. Their current daily net income is negative, nearing the shutdown threshold.In contrast, the new generation of high-efficiency liquid-cooled models has shown more resilience. Data shows that the shutdown price for Antminer S23 Hyd. is about $32,200 and is still in a profitable state. Models like S21 XP Hyd. have a shutdown price ranging from $40,000 to $50,000, indicating significantly better risk resistance compared to air-cooled models. Industry insiders point out that as the difficulty rises and the efficiency gap widens, this cycle is accelerating the stratification of miners into "new and old," with outdated models having increasingly limited profitability in the current market environment.

December 2, the Procuratorate of Wanbolin District, Taiyuan City, Shanxi Province, China recently announced the first-instance verdict of the case of Chen and Li, who were charged with concealing and disguising criminal proceeds. The court adopted the sentencing recommendations of the procuratorial organ and sentenced the two individuals to two years and six months, and one year and six months of imprisonment, respectively, along with fines.In May this year, Ms. Zhang met "Lin Hao" (at large) on a short video platform. "Lin Hao" falsely claimed to be a comrade-in-arms working for a well-known company, holding insider information on the company's stock price movements. He claimed that he could register an account on the company's internal website to "buy high" and profit (alleging a 5% return each period), but the transaction had to be conducted in US dollars. Moreover, it required exchanging cash for dollars with a designated merchant, then transferring it to his comrade-in-arms' dollar account, from where it would be transferred to the company's account.On May 21, following "Lin Hao's" instructions, Ms. Zhang carried 1.47 million RMB in cash to a hotel in Wanbolin District to exchange for US dollars. Acting on orders from their superior, Chen and Li went to meet Ms. Zhang. Ms. Zhang forwarded the US dollar account provided by "Lin Hao" (actually a scammer's Tether account) to the superior through Chen, who then transferred 202,328 USDT (equivalent to about 1.47 million RMB) to that account in three installments. Chen and Li then received the 1.47 million RMB in cash from Ms. Zhang and handed it over to their superior. However, "Lin Hao" did not transfer the money to Ms. Zhang's account as agreed, prompting her to report the scam to the police.The prosecuting attorney immediately reviewed the case files and consulted with the investigators, proposing a core investigative direction regarding the behavior of the suspects Chen and Li: obtain chat records to establish evidence that the two were "well aware of the abnormality of the funds"; clarify the fund flow route, trace the ultimate flow of USDT through the virtual currency trading platform data, and verify their objective participation in transferring the criminal proceeds. After investigation, the public security organ transferred the case to the Procuratorate of Wanbolin District on August 17.After examination, the Procuratorate found that both Chen and Li confessed that they "knew the fund operations were too secretive, and it involved a large amount of cash transactions, which certainly raised suspicions." The two individuals received a bribe of 30,000 RMB afterward, which was sufficient to establish that they were well aware that the funds were proceeds of crime; their assistance in completing the "cash to USD to USDT" cross-border conversion constituted an act of "concealing and disguising criminal proceeds."After the verdict, the Procuratorate issued a risk alert letter to relevant units, outlined the typical characteristics of "investment scams + virtual currency money laundering," and conducted anti-fraud education campaigns in collaboration with the Anti-Fraud Center and other relevant units. Sun Yinpeng, the Chief Prosecutor of Wanbolin District Procuratorate, stated that regarding new types of telecommunications network-related crimes, the Procuratorate will continue to deepen the "investigation-prosecution coordination + precise prosecution + social governance" mechanism, cracking down on both fraudulent crimes and severely punishing criminal "accomplices" to fully safeguard public property security.

December 2nd, several Coinbase shareholders have filed a lawsuit against the company's executives, accusing them of engaging in insider trading worth billions of dollars over the years. The lawsuit, filed in Delaware, alleges that Coinbase's top management and investors have concealed the company's failures in implementing Know Your Customer (KYC) and Anti-Money Laundering (AML) regulations, vulnerabilities to data breaches, and the extent of regulatory scrutiny into these issues.During the period when this information was allegedly concealed, internal personnel at Coinbase, including CEO Brian Armstrong and board member Marc Andreessen, sold $4.2 billion worth of company stock. The plaintiffs claim that these profits constituted "large-scale insider trading," taking advantage of the artificially inflated stock price of Coinbase.
