Based on on-chain analytics from CryptoQuant and Glassnode, long-term holders (defined as those holding BTC for 155+ days) accounted for approximately **80%** of the Bitcoin selling volume in October 2025. This is derived from LTHs offloading ~405,000 BTC (worth ~$43 billion at average prices), representing the dominant share of total exchange inflows estimated at ~500,000 BTC for the month amid heightened volatility and profit-taking. Other cohorts like miners contributed ~210,000 BTC, but LTH distribution was the primary source of pressure, with exchange inflows from LTHs nearly double historical norms.
