Bitcoin is currently in a phase of convergence oscillation + inflection window, with intensifying divergence between bulls and bears, characterized mainly by consolidation at higher levels and cautious sentiment. In the short term, influenced by macro sentiment and capital rhythm, prices are experiencing repeated tug-of-war in key zones, with limited rebound strength and downside finding support. At the 4-hour level, the Bollinger Bands are narrowing, moving averages are flattening, showing typical accumulation structure before an inflection point, dominated by range-bound oscillation. On dips supporting consolidation, go long cautiously; on rebounds meeting resistance, go short. Bitcoin 71500 to 72000 short, watch 69000. Ethereum 2190 to 2220 short, watch 2100.
