Clues Behind the Sky-High Eyewash: In-Depth Analysis of the "Xinkangjia" Incident
Recently, a chilling "farewell letter" has been circulating online, filled with sarcasm and contempt for the victims. This message is said to belong to the mastermind behind the "Xinkangjia" project, which has become a major financial fraud case involving 2 million people and 13 billion yuan.
This eyewash disguised as a stablecoin, under the banner of cooperation with a Dubai exchange and a large energy company, attracted a large number of middle-aged and elderly individuals and self-employed workers from third and fourth-tier cities with enticing promises of "capital protection and high interest." However, as the platform stopped withdrawals, the main suspects have fled overseas, leaving a mess behind.

Assessment of the Federal Reserve's Independence and Economic Stability
A former senior official of the Federal Reserve recently stated that even if the political landscape changes, the independence of the Federal Reserve and the core economic indicators are expected to remain stable.

This official expects that even if new immigration policies emerge, they are unlikely to have a significant impact on the labor market.
It is worth noting that these comments come just before the release of important economic data. The upcoming Consumer Price Index report may show that, in the context of a strong job market and a robust economy, inflation in the United States is only slightly cooling by the end of 2024. This data could influence the Federal Reserve's future interest rate decisions, making it cautious about rate cuts.
