**Bitcoin Analysis:**

The 1-hour chart shows a short-term rally losing momentum. After touching a high of 2169.37, the price has pulled back and is currently trading at 2156.21, with bullish momentum significantly weakening. The KDJ indicator shows K value at 78.79 and J value at 95.74, turning down from the overbought zone, indicating the uptrend has exhausted its energy and faces correction pressure. The moving average system shows consolidation after a failed rally attempt, with price breaking below short-term MA support. The 2160-2170 resistance zone above creates substantial overhead pressure, making it difficult for bulls to sustain breakthroughs. Subsequently, prices are likely to oscillate downward along the moving averages. Watch for 2140 support breakdown below, which could trigger further decline toward the 2120 area. Overall trading strategy favors shorting on rallies.

**Trading Recommendation:** Short 2180-2210, target 2100-2050 $BTC $GT
