Major mainstream cryptocurrencies show divergence during the nighttime trading session, which warrants close attention.

**Bitcoin (BTC)** remains in an upward trend on the daily chart, with the four-hour timeframe finding support at a key level. The short-term rebound is gradually gaining strength. If it can break through the previous high resistance, there is room for further upside.

**Ethereum (ETH)** performs relatively steadily, oscillating within the main support zone. Trading volume has mildly increased, but the momentum is still not strong enough. It is necessary to observe whether it can effectively break through the upper consolidation area.

**BNB** and **SOL** demonstrate stronger independence. BNB maintains resilience supported by active on-chain ecosystem activity, with a focus on key breakout levels. SOL has been active recently, with relatively positive capital flow, but short-term high-level pullback risks should be watched.

Overall, all cryptocurrencies are at critical junctures, with technical indicators showing signs of bottoming out and rebounding. However, effective volume confirmation is needed to verify reversal signals. It is recommended to closely monitor the gains and losses of major resistance and support levels to prepare for subsequent operations.
