Bitcoin's movement today has basically met expectations — the volatility has narrowed, with repeated consolidation in the 91500-90000 range, while Ethereum remains trapped in the narrow 3130-3100 band. The short-selling idea provided this morning still offered opportunities for traders who followed up promptly.

The current rebound is clearly losing momentum. Bitcoin encountered resistance at 91600, and Ethereum also stalled at the 3150 level, failing to break through smoothly. From a technical chart perspective, this rebound is essentially just a weak correction within the downtrend. On the 4-hour K-line, the Bollinger Bands have turned downward, and after price broke below the lower band, a small positive candle appeared for a pullback. However, moving averages and various indicators remain in a weakened state, providing us with opportunities for repeated short-selling.

This evening, attention should be paid to non-farm payroll data, unemployment claims data, and announcements related to US tariffs, as these news items may cause market volatility. Afternoon trading is expected to continue oscillating within the narrow range before the news release. Currently, coin prices are holding above the Bollinger middle band. If they further test the resistance of the upper band around 91500 and achieve an effective breakthrough, it may open upside space toward the 93000 area; if the breakthrough fails, a downward pullback is within expectations. Short-term strategy remains to maintain a high short-selling bias, with focus on monitoring the effectiveness of upper band resistance.
