According to @rovercrc, Bitcoin (BTC) crashed while exchange reserves kept falling on Oct 18, 2025 (source: @rovercrc tweet, Oct 18, 2025). The post provides no exact price change, no exchange-specific breakdown, and no reserve figures, only the directional observation of a price drop alongside declining balances (source: @rovercrc tweet, Oct 18, 2025). For trading, this observed divergence warrants focusing on real-time net exchange flows, order book depth, and derivatives funding and basis before adding risk, since the post indicates the selloff is not accompanied by reported rising spot balances (source: @rovercrc tweet, Oct 18, 2025).
