According to BitMEX Research, 87% of the total Bitcoin (BTC) supply has now been mined, marking a significant milestone that directly impacts trading strategies and long-term price forecasts. This update, shared on June 21, 2025, underscores increasing scarcity, which historically has influenced upward price momentum and heightened volatility in the BTC market. Crypto traders should closely monitor supply metrics, as reduced new issuance can intensify supply-demand dynamics, potentially affecting both spot and derivatives markets.
