Although ETH broke through $4,000 today, there has not been a significant FOMO sentiment in the overall market, and the positive impact of 401K entering the crypto market has not significantly increased BTC purchasing power. Trading volume remains normal, and the price increase is more due to reduced selling pressure. In contrast, ETH trading volume has significantly increased after the news was released, and the spot ETF $ETH has also seen a corresponding increase, indicating that funds are leaning towards ETH, especially with traditional ETF funds activating both primary and secondary markets. The U.S. stock market performed strongly, with the Nasdaq hitting a new high and the S&P approaching historical highs, which may provide indirect support for BTC.
