Bitcoin ($BTC ) and Ethereum ($ETH ) are under pressure as markets await two key macro events next week.

The ECB is widely expected to raise rates by 25 bps on September 10, while the U.S. CPI report on September 11 will shape expectations for the Fed's September 16 decision.

Inflation is forecast to remain at 3.4%, leaving traders divided on another Fed rate hike. Higher inflation or a more hawkish stance from central banks could weigh on crypto and other risk assets. However, softer inflation data may boost sentiment and trigger a strong rebound in both BTC and ETH.
