BNB experienced a significant drop on December 11, with a notable increase in 1-hour trading volume. The cryptocurrency has now retested the 0.5-0.618 Fibonacci retracement range, finding support around $860. Derivative markets indicate near-neutral funding rates at 0, reflecting cautious market sentiment with a slight bullish inclination. If the current support level holds, BNB could rebound towards $890. However, a sustained breakdown, confirmed by four consecutive 4-hour candles below $1.98, might lead to a test of the $840 level. Traders are advised to monitor these key levels closely over the next 1-2 days.
