Bitcoin yesterday mostly maintained a narrow range of 77,000-78,500 with sideways consolidation, market fluctuations back and forth, and intense battles between bulls and bears. The price repeatedly tested lows and rebounded, then surged and pulled back, showing typical signs of a high-level shakeout and chip rotation. Technically, the price stayed close to the short-term moving averages, with Bollinger Bands tightening and volatility converging. The MACD green and red bars alternated and shortened, indicating diminishing momentum. This suggests a short-term unclear direction and a balance of buying and selling forces. After a quick rebound from a key support at 76,900 in the early morning, confirming strong buying interest below, the price faced repeated resistance in the 78,500-78,600 range, with selling pressure clearly increasing. Overall, the long-term bullish structure remains intact, but short-term momentum lacks upward power. The market is likely to continue oscillating within the 77,000-78,500 range, awaiting volume and news catalysts for a breakout. Trading strategy should focus on buying low and selling high within the range, and following the trend after a breakout.
