ETH has increased in price over the past 4 hours, but trading volume has contracted, indicating weakening momentum. Regarding technical indicators, MACD is gradually shortening, and KDJ is oversold, suggesting a potential rebound. Key levels at 3137.58 and 3117.01 are suitable for long positions, while 3367.0 is a major resistance level. Despite the risks, the technical outlook still shows bullish hope, and trading should be based on individual risk management strategies.
