Bitcoin Drops to $66K as Coinbase Premium Turns More Negative, Signaling U.S.-Led Selling

Bitcoin has fallen sharply from $74,000 to around $66,000 as selling pressure from U.S.-based investors intensifies, according to recent market data.Data from Coinglass shows that the Coinbase premium—a key indicator of U.S. spot demand—has remained negative and widened since March 19. A negative premium indicates that Bitcoin is trading lower on Coinbase compared to offshore exchanges, typically signaling net selling activity from U.S. participants.The trend coincides with Bitcoin’s latest correction, suggesting that U.S. investors have been a primary driver of the downside move.This divergence reflects broader market dynamics, where institutional flows and macro conditions are increasingly influencing price action. Weak demand from U.S. spot markets also aligns with recent data showing declining volumes and limited buying interest during rallies.
