BTC: Focus on whether the 4-hour chart can close above the support zone of 74,000-73,300. This range is not only a previous dense trading zone but also if the current RSI on the 4-hour level shows a bullish divergence and a golden cross simultaneously, the safety margin for long positions is higher. In terms of operation, if the candlestick body stays above 73,300 and is accompanied by a shrinking MACD bearish momentum histogram, you can attempt long positions relying on this area; conversely, if volume increases and breaks below 73,300 turning downward, abandon the bullish strategy. Short-term resistance above is at 76,100; a breakout requires observing whether trading volume increases accordingly.

ETH: The strong resistance above is at 2,390, where the 4-hour Bollinger middle band and EMA30 moving average converge. Only with increased volume and a steady hold at this level can a rebound toward 2,420-2,450 be expected. Short-term support below is at 2,230; if the 4-hour closing price falls below this level and the MACD forms a death cross, all low-long positions should be abandoned, with the downward target revisiting the weekly demand zone around 2,180.
