Coinbase's Bitcoin premium has remained negative for seven consecutive days, indicating weak U.S. spot demand as the year-end approaches. This trend is attributed to tax-loss harvesting activities, which have led to increased selling pressure in Western markets. Meanwhile, Asian buyers are capitalizing on lower prices, a move that aligns with historical patterns of shifting support and resistance levels. Traders are closely monitoring these dynamics, particularly key support levels, for signs of a potential rebound in Bitcoin prices.
