Bitcoin's four-hour chart surged to 71500 before pulling back, maintaining wide-range oscillation and still operating within the previous range with no breakthrough momentum in the short term. Bollinger Bands continue to contract, combined with Friday's market action, focus on the performance of US stocks.

On the hourly chart, the price broke below the middle band but quickly recovered with a large bullish candle, with the rebound continuing and MACD showing bullish dominance. However, the overall K-line structure shows limited upside space as the stimulus effect from US stocks weakens. Operationally, focus remains on shorting rebounds at highs.

Bitcoin: Short near 70800-71500, target around 69000, continue watching if broken below, otherwise go long.

Ethereum: Short near 2090-2130, target around 2000, continue watching if broken below, otherwise go long.#比特币支撑阻力位分析 $BTC $ETH
