That day's view: Yesterday BTC closed at $75,644.48, opened at $78,189.20, high $78,250.46, low $74,967.97, down 3.25% for the day, showing a volume-breakdown structure; 24h volume was 21,683 BTC, with no significant contraction compared to the prior average, active selling dominating; funding averaged +0.00588%, still maintaining the long-paid range, but the premium relative to the previous day has declined, no flip observed; OI rose from 103,517 to 107,492, up 3.84%, price falling while open interest rising, a typical (c-mix) signal: active short accumulation combined with passive long liquidation, but the positive funding leans more toward short-side dominance; FGI reported 69, in the greed zone for four consecutive days, showing a clear divergence with the price breakdown - a short-term warning signal. Comprehensive judgment: short-term momentum leans bearish, watch the $74,000 round number and $73,000 prior concentration area for support; if $77,000 resistance cannot be reclaimed, the bearish structure will continue; event-wise, closely monitor Fed officials' speeches this week and whether ETF fund flows continue net outflow.
