Last night to early morning, BTC/ETH surged again in tandem, with highs touching around 73,100 and ETH probing the 2,200 level. Both pairs approached recent stage highs before facing selling pressure and pulling back, with upper resistance showing significant suppression effects.

From a technical perspective, both the 4-hour and daily timeframes exhibit a pattern of rallying followed by pullback. The candlestick bodies are narrowing with notable long upper wicks, reflecting insufficient bullish momentum and concentrated selling pressure at higher levels. As prices encounter resistance near previous highs and retreat, this further confirms strong resistance at the upper band of the current range. Short-term bulls lack effective breakthrough conditions, so today's strategy focuses on selling rallies.

**BTC**: Recommend shorting around 73,300-73,900, targeting 71,500 and 70,000 levels below.

**ETH**: Short on bounces around 2,200-2,230, targeting 2,120 and 2,085 levels below.
