From the one-hour level of Bitcoin, the Bollinger Bands continue to narrow, and price fluctuations are tightening. Although there was a brief break above the middle band, it quickly fell back, indicating insufficient momentum from both bulls and bears, and the oscillation pattern remains unchanged. It is advised to pay attention to the pressure at the upper edge of the range; if there is no effective breakthrough or a reversal signal appears, consider entering a short position. Conversely, we can buy at the lower levels.
