Bitcoin overall shows a pattern of oscillating pressure and weak rebounds. Starting from the high point of 69,005 early this morning, it began to decline, gradually breaking below short-term support during the sideways movement, with the lowest dip reaching around 67,833. Ethereum is highly correlated with Bitcoin, weakening simultaneously from the high of 2,138, falling back to around 2,072, showing a weak follow-through trend, and the market's correlation remains evident.

On the daily chart, the downward channel remains intact. After a brief rebound and correction, the price failed to break through key resistance levels. Bullish momentum has weakened, moving averages are gradually turning downward, forming a bearish resonance suppression, and the trend has reverted to a bearish dominance, with a weak and persistent structure.

The four-hour chart continues to show a sideways downward trend, with prices repeatedly facing resistance at the midline. Rebounds are weak, and pullbacks are intensifying. Technical patterns are bearish, further confirming the daily chart's weak foundation.

Current momentum indicates: bearish forces are dominant, and short-term rebounds are mainly trap moves to induce buying, with the core purpose of exhausting bullish buyers and accumulating energy for further declines. The main trading strategy today: position for short entries on rebounds, mainly shorting at high points.

Specific trading suggestions: monitor resistance in the 69,250-69,800 and 71,250-71,800 ranges. If these levels hold without breaking, consider short positions at high points, aiming for a 5,000-6,000 point decline. A move above 71,800 is seen as a trend reversal.
