The morning Bitcoin attempted to push up to around 92400 resistance but encountered resistance and retraced, with a low of 91000 integer support and currently consolidating around 90700. Ethereum's trend is largely consistent with Bitcoin, rebounding to the key resistance level of 3170 before also pulling back.

The daily chart continues to show a volatile pattern, with trading volume steadily decreasing, and the lower boundary of the range support remains effective. To open up upward space, a genuine breakthrough of the key resistance above is needed; otherwise, the short-term consolidation pattern may continue. Given that recent prices have repeatedly tested the upper levels without breaking through and the support below remains solid, buying on dips after a pullback remains the main strategy. The four-hour trend shows a typical "draw a door" pattern; although a trend has not yet formed, the lows are gradually rising, and each pullback near moving averages can rebound, indicating strong support below and that bulls still have the capacity to recover. Short-term trading can continue to revolve around the range, maintaining a general approach of buying on dips.

Bitcoin can be bought within the 90300-90000 range, aiming for around 93000;
Ethereum can be bought within the 3070-3090 range, aiming for around 3210.
