Bitcoin Supply Hits 20M — Last ~1M Likely by 2140
On-chain data from Glassnode shows Bitcoin’s circulating supply has crossed 20,000,000 BTC after block 940,000, roughly 6,267 days (~17 years) since genesis. That represents over 95% of the 21 million cap. Bitcoin has undergone four halvings; the current block subsidy is 3.125 BTC and halvings—occurring about every four years—will continue to cut issuance. At current issuance rates, the remaining ~1,000,000 BTC are projected to be mined across a long tail of roughly 114 years, implying final issuance near 2140. The supply milestone underscores Bitcoin’s capped-supply scarcity, a structural bullish fundamental for long-term holders and allocators. However, miners face a structural revenue transition: block-subsidy income will vanish as issuance ends, leaving transaction fees as the sole on-chain reward. Present fee levels are insufficient to fully replace subsidy revenue, posing a long-term economic-model risk for miners that could affect miner behavior and network dynamics. Traders should note the milestone’s signalling effect on long-term supply-side scarcity, but near-term price action will remain driven by demand, macro factors, liquidity and miner-selling dynamics. At the time of reporting BTC traded near $70,800, up over 5% on the week.

Bullish
Crossing 20 million BTC reinforces Bitcoin’s capped-supply narrative, which is a structural bullish factor for long-term price expectations because it highlights diminished net-new supply. For traders, the immediate effect is likely muted: price moves will depend on demand, macro conditions, liquidity and miner behavior rather than the milestone alone. The miner-revenue issue (declining subsidies and reliance on transaction fees) introduces a long-term risk that could increase miner selling or prompt network-level adjustments, adding potential volatility. Historical market responses to supply-related milestones tend to be mixed — supportive for long-term accumulation but not an automatic short-term price catalyst. Overall, the net effect favors a bullish long-term outlook while leaving short-term price direction dependent on other market drivers.
