To assess potential selling pressure by analyzing changes in Bitcoin exchange reserves, monitor the net inflow or outflow of BTC on major exchanges. A rising reserve suggests more Bitcoin is being deposited, possibly signaling intent to sell, which could increase supply and pressure prices downward. Conversely, declining reserves indicate withdrawals, implying holders are moving BTC to cold storage, reducing available supply and potentially easing selling pressure. Track data from platforms like Glassnode or CryptoQuant for real-time insights. Combine this with on-chain metrics—such as transaction volume or whale activity—and market sentiment from X posts or web searches to gauge broader trends. Sharp reserve spikes often precede volatility, so timing matters. This method offers a data-driven way to anticipate market shifts without relying solely on price action.
