4490 (1-2 hour level): This point is the 'line of life and death' for the short-term trend, whether it holds or not directly determines the subsequent tendency to rebound or dip.

II. Key points above and below the watershed

- Above the watershed (rebound market)

- Support: No need to pay extra attention to support, 4490 itself is the basic support level for the rebound, if it holds, the rebound will continue.

- Pressure (watch the rebound height in order): 4540 → 4583 → 4630

- Below the watershed (weakness/down market)

- Pressure: After falling below, 4490 will turn into a short-term pressure level for the rebound, and it is easy to encounter resistance and fall back when rebounding to this point.

- Support (in order of depth of correction): 4421 → 4370 → 4330

Three, core summary

Short-term operations closely monitor the stability of 4490 at the 1-2 hour level: if stable, respond with a rebound strategy and gradually look at the three levels of resistance above; if not stable, determine it as a weak rebound, and need to guard against the risk of a downward probe, with a focus on the support level below and its strength of holding, the operational strategy needs to be adjusted in real time according to the gains and losses at this point.$ETH #以太坊走势分析
