From the 4-hour K-line chart, ETH quickly stabilized after touching the lower boundary support area of the upward channel, forming a relatively clear counterattack pattern.

Currently, the market shows several signals worth noting. First, there is a clear sign of a halt in the decline and a rebound above the support, indicating that buying interest is active at lower levels; second, the strength and rhythm of the rebound appear orderly, without signs of a frantic surge driven by greed.

The subsequent trading logic is quite straightforward—closely monitor whether the lower boundary support can continue to hold. As long as this support line is not effectively broken, you can continue to operate around a low-buy strategy. If it does break, then a reassessment of subsequent risks is necessary. In the short term, the focus should remain on the stability of the support.
