Today, Bitcoin is showing a overall oscillating downward trend, with a decline from the 68100 level in the early morning under pressure. The rebound is weak, and it has tested short-term support multiple times, with a low of around 66500. The bullish momentum is relatively weak, and the market's center of gravity continues to shift downward. Ethereum remains highly correlated with Bitcoin, both starting to decline from the 1980 high point, dropping to the 1900 support level. The weakness and follow-through decline are obvious, indicating a predominantly bearish correlation.

On the daily chart, the upward channel has been broken. After encountering resistance during the previous rebound, the price failed to hold key moving average supports. The moving average system has turned downward, creating resistance, and the trend has officially shifted to a bearish dominance. The previous oscillating upward structure has been broken, and the downside risk continues to be released. The four-hour chart continues to show a weak downward trend, with prices steadily declining along the lower boundary of the channel. The rebound highs keep moving lower, and the technical indicators show a one-sided bearish bias, further solidifying the daily bearish trend. Currently, the market rhythm indicates that the bears still dominate, and short-term rebounds are mainly trap moves to induce longs, not trend reversals. The core purpose is to test support levels and prepare for further declines. Today's early operations should focus on rebounding to set up short positions.

Specific trading suggestions: Pay attention to the resistance at the 67300-67800 and 68800-69500 zones. If the price holds above these levels without breaking, consider shorting at higher levels, aiming for a downward move of 500-6000 points. Only when the price stabilizes above 69500 should a trend reversal be considered.
