From the four-hour K-line chart analysis, the current market shows a short-term strong rebound pattern, with momentum significantly increasing, driving the trend to continue upward. Both sides are engaged in a tug-of-war in the key resistance zone.

However, the overall technical structure indicates that the downward trend has not undergone a substantial change, and the long-term trend still maintains a relative advantage. It is recommended to maintain a cautious approach in operations, taking short positions on rallies and seizing rebound opportunities during the pullback.

The major coin can be initially observed for a rebound around 82500-82700 before falling, with a target of 80700.
