From the four-hour level structure, the price of Bitcoin has recently shown a significant weak oscillation pattern. On the technical side, the price first experienced a small pullback, and then gradually moved away from the middle track of the Bollinger Bands, with the overall operating range consequently shifting downward. Currently, the trend of the Bollinger Bands is significantly narrowing, and the opening direction is most likely to continue downward, indicating that the subsequent volatility may further contract, but the directional choice is approaching a critical point.
