What Is Exchange Netflow?
Exchange netflow is the net difference between crypto deposits to and withdrawals from exchanges during a given period. Positive netflow (more inflows than outflows) means coins are moving to exchanges — potential selling pressure. Negative netflow (more outflows than inflows) means coins are leaving exchanges — typically accumulation.
How Exchange Netflow Works
Exchange netflow is calculated for specific assets (BTC exchange netflow, ETH exchange netflow) and aggregated across all tracked exchanges. Sharp positive netflow spikes during rallies are immediate warning signs: holders are sending coins to exchanges to sell into strength. Persistent negative netflow during a bear market is a strong accumulation signal — coins are being withdrawn for long-term holding.
Why It Matters for Traders
Exchange netflow is one of the most actionable on-chain metrics because it directly measures the balance of supply entering and leaving the most liquid selling venues. A sudden $500M positive BTC netflow during a rally creates measurable sell pressure that often manifests in price decline within hours. Monitoring netflow in real-time provides early warning of supply-demand shifts before they're visible in price.
