Evening bitcoin experienced a sudden news catalyst, with sharp short-term rallies exceeding 3000 points, reaching highs near 71800. Ethereum surged in sync, currently maintaining high-level consolidation.

From the chart perspective, this round of gains is entirely driven by geopolitical news, representing a typical pulse-like rebound lacking sustained volume support. At the 4-hour level, price has pierced the Bollinger upper band, but MACD red column momentum lacks sustainability; the 1-hour chart shows a pullback with a long upper wick after the surge, indicating significant selling pressure at higher levels. This has not formed the structural and volume foundation for a trend reversal. The subsequent main tone will be a weak pullback, and the short-bias trading strategy remains unchanged!
