According to @WatcherGuru, BTC fell below $86,000 on Nov 21, 2025, marking a break of a key round-number level that traders monitor for momentum shifts (source: Watcher.Guru on X, Nov 21, 2025). A decisive undercut of such levels can cluster stops and elevate long-liquidation risk on leveraged venues, prompting monitoring of funding, open interest, and liquidation heatmaps for confirmation (source: Binance Academy, Support and Resistance; Coinglass liquidation metrics primer). Near-term execution commonly focuses on the next liquidity areas such as $85,000 and prior swing lows, alongside spot-perp basis and order-book depth on major exchanges to judge continuation versus mean reversion (source: Binance funding and order book dashboards; TradingView market data).
