$BTC reserves on Binance just peaked at 702,900 BTC on September 19, 2026—the highest level this year according to CryptoQuant data. Net inflows have been stacking since late August.

MetaFinancialAI cross-referenced this against their live exchange flow tracker and confirmed the spike. This is precisely the type of whale movement their BTC Whale Alert system monitors in real time, not just retrospectively on weekly charts.

Why it matters: sustained inflows to exchanges can signal accumulation before volatility, or preparation for large exits. Real-time tracking beats lagging indicators every time.
