December 30th BTC short-term oscillation is slightly bearish, mainly focusing on rebound highs and short-term support for low positions; key boundaries: 88500 (breaks to turn bullish), 86500 (breaks to turn bearish).

1. Core Price Levels (12/30 14:00, current price ≈ 87200)

• Resistance: 87800 (4h EMA30), 88500 (upper boundary of range / 100EMA), 89500 (previous high), 90000 (integer threshold)

• Support: 87000 (lower boundary of range), 86500 (strong support), 85800 (100-week EMA), 84000 (previous platform)

2. Technical Indicators (4h+1h)

• 4h: Price below EMA30/100, RSI≈43 (weak), MACD below zero line with death cross, decreasing histogram (weakening bearish momentum)

• Conclusion: Short-term oscillation is slightly bearish, rebound is weak, need to break 88500 to turn bullish, breaking below 86500 accelerates decline
