BTC short-term rapid V-shape reversal, essentially driven by major players washing out high leverage and harvesting short-term funds.

Between 85K-90K, both bulls and bears are balanced, selling pressure has dried up but no new funds are entering, a 5000-point liquidity vacuum, small funds can easily push the market down 1-2%, which is just sweeping liquidity and not a true trend.

Yesterday, the US stock market's funding rate was neutral; after a 2% dip at the open, the rate turned negative. High-leverage longs were liquidated, and sentiment cooled down.
Overall, the bullish trend remains unchanged, with 84K as a clear support (the dip to the 12/1 low point triggered a pulse rally, multiple re-tests without breaking), indicating a bullish structure.

US institutions are on Christmas break, and the market is approaching a starting point. BTC has shown signs of decoupling from the US stock market; yesterday, the US stock market's lack of major upward movement was a test of the waters, and the pullback was just consolidation, so there's no need to panic.
