Evening Bitcoin and Ethereum prices are stuck in a back-and-forth pattern, with the bearish pressure continuously strengthening.

Trading suggestion: Bitcoin can consider shorting in the 89500-90400 range, targeting around 87000; Ethereum can short in the 3120-3080 range, with a target near 2950.

The support levels given in the morning are still being tested repeatedly. During the midday session, Bitcoin briefly surged to around 89900, and Ethereum also climbed to a high of 3068. However, the market then fell into a stalemate, with the bullish rebound momentum clearly suppressed, and the bearish pressure re-emerging.

From the four-hour K-line chart, the price has been oscillating within the upper band of the Bollinger Bands. Although multiple attempts have been made to test the resistance above, the rebound momentum remains weak. The 90000 USD level has become a clear strong resistance. Subsequent rebound attempts have failed to break through effectively, so a bearish outlook can be confidently maintained.

Switching to the hourly chart, the bearish signals are gradually strengthening. The long upper shadows left during the short-term rebounds are particularly obvious, indicating that the downward trend has entered a phase of sustained pressure. The key focus moving forward is whether this resistance zone can continue to hold.
