ChainThink report: On December 29, AI-driven technical analysis indicates that BTC generated a bullish signal on December 25. The price has now surged into the first resistance zone—89,500–90,500—marking the neckline resistance of the double bottom pattern and a confluence of multiple supply zones. However, the current intraday large bullish candle has pierced above the Bollinger Band middle band, which had remained unbroken for nearly half a month, signaling bullish momentum. OBV has turned upward, volume has resumed strength, yet BTC must not re-break below the critical support near $88,500. This level serves as both the Bollinger Band middle band support and the breakout point of the ascending triangle's upper trendline. A daily close below this level would invalidate short-term bullish signals, triggering a return to consolidation and potentially testing the $86,000 support again.

If the price maintains its defense, it may target the upper boundary of the VPVR value area at VAL $93,000. (AI analysis, not investment advice, valid for 1–5 days)
