Bitcoin's market dynamics are showing promising signs as the Coinbase Premium Index (CPI) turns positive for the first time in 2025, coinciding with Bitcoin surpassing the $102K mark. This shift highlights the significant impact of U.S. investors, particularly following the approval of Spot Bitcoin ETFs. The recent outflow of 4,012 Bitcoin from Coinbase further underscores the increasing buying pressure from U.S. investors. These developments suggest a renewed bullish sentiment in the crypto market, driven by strategic investor behavior and regulatory advancements.
