Reading Exchange Inflow and Outflow Signals
Exchange flows track the movement of Bitcoin between wallets and centralized exchanges. When large amounts of BTC move into exchanges, it can signal that holders are preparing to sell — increasing the liquid supply on order books and potentially applying downward price pressure. Conversely, when large amounts of BTC leave exchanges and move into private wallets, it suggests holders are withdrawing to self-custody — reducing exchange supply and often interpreted as a bullish long-term signal.
The BTC.PH Exchange Flows tool analyzes recent large transactions from mempool.space and uses label heuristics and round-amount patterns to classify them as exchange-related inflows or outflows. Because Bitcoin addresses are pseudonymous and not all exchange addresses are labeled, this is a directional signal rather than precise accounting data. For individual address lookups, use the Wallet Lookup tool. For market sentiment context, check the Fear & Greed Index.
