The four-hour Bitcoin cycle maintains a continuous bullish consolidation upward pattern, with the Bollinger Bands gradually narrowing overall, and the price repeatedly testing upward but frequently showing pin-like formations. The resistance above is very strong, and the bullish buying momentum remains weak. Each rebound reaches a high point but faces resistance and falls back, making it difficult for the short-term trend to break through, and the overall enters a range-bound oscillation rhythm.
