The daily Bitcoin mined supply sits at 450 BTC. Yet in just two days, spot Bitcoin ETFs accumulated 16,500 BTC through net purchases. That's equivalent to 36 days' worth of mining output absorbed in a mere 48 hours. The imbalance reveals something striking: institutional buying through ETFs is now vastly outpacing new supply entering the market from mining. This demand-supply squeeze could have significant implications for Bitcoin's price dynamics, especially as more capital flows into these regulated investment vehicles.
