US initial jobless claims near 57-year low, strong domestic demand drives profit growth.
Last week, the number of new US jobless claims fell to its lowest level in nearly 57 years, with layoffs easing and the labor market stabilizing. Data from the US Department of Labor shows that for the week ending October 17, initial state unemployment benefit claims dropped by 6,000 to a seasonally adjusted 194,000. This figure is approaching the 189,000 level hit in mid-July, marking the lowest since 1969. Economists believe that strong US domestic demand has driven rising profits, shielding workers from layoffs. However, as the conflict between the US, Israel and Iran intensifies, tighter financial conditions and rising interest rates may weigh on the labor market’s performance next year.

Meme coin project Zipcoin, which centers on a fictional narrative about Vitalik, announces it is shutting down.
Meme coin project Zipcoin, built around a narrative from Ethereum co-founder Vitalik Buterin’s novel, has announced its shutdown. The team stated it received a notice from Railway on October 21, alerting that the entire project codebase had been compromised, including all associated credentials and private keys. After attempting to migrate or rotate credentials, the team failed to identify a viable secure operating solution. The team will offer a six-hour selling window for existing holders, and will liquidate remaining holdings and pool funds at 00:00 Beijing Time on October 23 to prevent attackers from siphoning assets. According to GMGN data, ZC (Zipcoin) has dropped over 90% in the past 24 hours, with a current market capitalization of less than $300,000. Zipcoin’s narrative originates from a fictional currency in Vitalik Buterin’s novel *Snowmoon*. Designed as an on-chain currency with features including anonymous payments, burnable for advocacy, and real-time taxation, the project sought to translate concepts from the novel to the real blockchain.
