CMC News Update - September 4, 2025

NEW YORK, September 4, 2025 - CoinMarketCap (CMC) highlighted two key developments today affecting the cryptocurrency market:

1. Bitcoin Faces September Pressure CMC posted on X (formerly Twitter) that Bitcoin is under increased selling pressure as macroeconomic risks intensify and the flagship cryptocurrency hovers just below the $100,000 mark. Analysts at K33 warn that ongoing concerns over central bank policy and global economic growth could weigh on Bitcoin’s price throughout September.

2. Altcoin Season Index at 53 Data from CMC’s Altcoin Season Index shows a reading of 53, signaling a modest tilt toward altcoin outperformance compared to Bitcoin. The index, which tracks the relative gains of the top 100 cryptocurrencies by market capitalization, suggests the market is in a transitional phase rather than a full-fledged altcoin rally.
