Bitcoin short-term trend: The four-hour chart shows the price moving along the lower band of the Bollinger Bands, with bullish momentum continuously shrinking. The bears are dominating the market rhythm.

On the one-hour chart, bulls and bears are alternating frequently but without any substantial breakthrough. The MACD crossover has failed to reverse the weakness. A subsequent pullback is highly probable. Maintain the high short positions in the afternoon and follow the market trend closely.

Trading suggestion: Short near 86,800-88,000, with a target around 84,800-83,000. If broken downward, continue to look lower; if not broken, follow the trend accordingly.
