Bitcoin’s supply is entering a critical compression phase as issuance nears the 20 million milestone, with only about 1 million coins left to mine. The 2024 halving reduced block rewards, slowing new supply creation, while accumulation from long-term holders and ETFs now significantly outpaces monthly issuance, tightening available liquidity.
Bitcoin’s supply curve is approaching a critical threshold, with 19,998,888.66 BTC already issued. Only 1,000,884 coins remain to be mined, stretching gradually toward the year 2140.
The 2024 halving reduced block rewards to 3.125 BTC, slowing new supply creation. Daily issuance now averages roughly 450 BTC, reinforcing the pace of supply deceleration.
Smaller holders absorbed roughly 19,300 BTC monthly in 2025, while miners introduced only about 13,500 coins. As accumulation increasingly outpaces issuance, supply compression grows economically meaningful, indicating that the demand for Bitcoin is rising faster than its availability in the market.
Long-term holder supply rebounded sharply, adding about 212,000 BTC within 30 days after a brief distribution period. Roughly 61% of the total supply has remained dormant for over one year, data from Glassnode shows, gradually reducing the liquid trading float.
Institutional custody amplifies this trend, with spot ETFs now holding about $86 billion in BTC. Exchange balances have simultaneously declined to 2.4 million BTC, reinforcing the illiquid supply structure.
Meanwhile, miner revenue has declined to roughly $29 million daily, increasing treasury liquidations. This demand increasingly outpaces the amount mined monthly, gradually tightening available supply.
