Ethereum has recently led the surge in cryptocurrencies, with prices rebounding sharply from around $3100 to a high of $3397, and now pulling back to around $3300 this morning. The daily chart has shown four consecutive days of gains, presenting a strong bullish trend.

Technical analysis: The daily EMA trend indicator is contracting upwards, forming a bullish trend. The K-line has broken through the upper Bollinger Band at 3286, MACD shows increasing momentum, and the DIF and DEA are close to the 0 axis; the four-hour K-line has deviated from the EMA trend indicator, MACD is rising, and the DIF and DEA are widening. However, there is short-term resistance at $3350 - $3400, and a further breakthrough of the MA60 moving average resistance is needed, as short-term indicators are overbought, indicating a demand for a pullback to digest the gains.

Everyone should cautiously wait for a pullback to the support zone of 3240-3290 to set up long positions, targeting the upper range of 3340-3380. If it breaks above and stabilizes at high levels, it can continue to rise.
