Bitcoin is exhibiting a bullish engulfing pattern on the daily chart, indicating a potential upward trend despite weak trading volume. The Bollinger Bands are narrowing, and the KDJ indicator is converging, suggesting reduced volatility and no definitive trend direction. Key support is identified near $86,000, while resistance is at $90,000. A breakout above $90,000 or a breakdown below $86,000 could signal a significant trend shift.
