Bitcoin retreated again after touching the 88,000 level in early trading today. This is already the multiple test within the concentrated chip zone (87,000-88,000). The market shows obvious oscillation characteristics, and it is expected that the Christmas holiday行情 will mainly consolidate within a range, so there's no need to rush to chase the trend.

From a technical perspective, Bitcoin today closed with a doji candlestick, with chips repeatedly争夺 between 87,000 and 88,000. According to the rhythm, the range resistance may persist until around 4 a.m. tomorrow, and the volatility may only end after the 8 a.m. close.

**Specific trading ideas**:

Looking upward, 88,000 is a short-term resistance level, and 89,600 is a stronger resistance. Once it hits 88,000, consider short positions, but leave a 8,000-point buffer (set stop-loss at 96,000), targeting the 2950/2920 zone.

Looking downward, 87,000 is support, and 85,850 is a secondary support. When falling to support levels, you can gradually add long positions, with defense points set at 86,300 and 84,400. Take profit targets are in the 87,500 to 88,000 range.

The logic for Ethereum is similar. In the short term, trade high short and low long within the 2900 to 2980 range. Resistance levels are 2965, 3015, and 3050. Rebounds can be sold in batches, with a stop-loss at 3085; support levels are 2918 and 2850. Add long positions gradually, with defense at 2880 and 2820, and take profit targets at 2895, 2950, or 2980.

Overall, today’s strategy framework is similar to this morning, and there are no clear breakout signals yet. Before tomorrow morning, do not take overly aggressive positions, just control risk properly. If there are any key changes, I will update accordingly. Wishing everyone smooth trading.
