#数字资产市场动态 December 30 Spot Market Observation:

Currently, $BTC is trading within a key support zone. The support levels below are sequentially 87000-87300 (lower boundary of the range) → 86000-86500 → 85769 (100-week moving average). These three levels are the main price points of recent defense. The resistance levels above are 88800 (4-hour upper band) → 90000 (psychological barrier) → 98581 (50-week moving average).

Technical indicators are interesting: the 4-hour EMA30 is at 87838, and the 7-day moving average is also around 87628, showing clear resistance. The MACD has formed a death cross below the zero line, but the histogram is shrinking, indicating decreasing selling pressure. On the daily chart, there is a bottom divergence signal—price makes new lows while MACD rises, which usually suggests that oversold rebound momentum is quietly building.

Trading strategy:

**Accumulation Phase**: Enter in batches within the 86000-87000 range, with a stop-loss at 85500. If a rebound occurs, gradually reduce positions around 88500-89000. If resistance is encountered at 90000, further reduce holdings.

**Mainly Bearish Approach**: Focus on shorting during rebounds, with long positions as an auxiliary. Keep a close eye on the 86000-88800 range. Short positions near 88500, with a stop-loss at 89200, targeting 87000-86500.

**Bullish Supplement**: Light long positions at 86200-86500, with a stop-loss at 85800, aiming for 87500.

In simple terms, the main strategy is to short on rebounds, with support levels as a secondary approach to buy dips, waiting for the bottom divergence momentum to fully release.
