The price fluctuation range of Ethereum ($ETH ) can be observed from the currently visible 0 to 5000 points, with 2500 points as the central price point. According to the principle of 'third time's the charm', we can temporarily define the large fluctuation range between 2200 points and 2800 points. Currently, the price trend of Ethereum is based on a fluctuating upward movement around 2500 points, having risen 250 points to 2750 points. At this price level, whether going long or short in the short term, the potential profit space is relatively limited.

If Ethereum can break through the current fluctuation range in a short time and stabilize around 2850 points, then the large fluctuation range may shift upwards to 2500 points to 3100 points. In this case, it is recommended that investors consider medium-term positioning, as short-term trading often carries higher risks, and based on experience, in short-term trading, nine out of ten times may result in losses, while one time may require holding a position.

Overall, the price trend of Ethereum needs to be closely monitored, especially the key support and resistance levels. Investors should adjust their trading strategies according to the actual dynamics of the market while paying attention to risk management to avoid unnecessary losses due to short-term trading.
