Bitcoins [BTC] The supply curve is entering a critical compression phase as issuance approaches the 20 million BTC milestone. The current supply is 19,998,888.66 BTC, which represents 95.23% of the 21 million limit.
As this threshold approaches, remaining issuance shrinks sharply. Only 1,000,884 coins to stay are mined, and will gradually extend until 2140.
At the same time, the 2024 halving will take place reduced block rewards up to 3,125 BTC, delaying new supply creation. Daily issuance now averages around 450 BTC, amplifying the pace of the supply slowdown.

Meanwhile, 230 BTC remain permanently unspendable, subtly reducing the effective circulating supply available to the markets.
This contraction is starting to shape market expectations. Smaller holders absorbed about 19,300 BTC monthly by 2025, while miners introduced only about 13,500 coins each month.
As accumulation continues to exceed issuance, supply compression becomes economically meaningful, indicating that demand for Bitcoin is rising faster than its availability in the market.
Gradually, the 20 million milestone strengthens Bitcoin’s scarcity narrative, strengthening its long-term positioning as a digitally scarce store of value.
The accumulation exceeds the new issuance of Bitcoin
Bitcoin’s supply dynamics continue to change as issuance slows post-halving, while long-term holders steadily absorb circulating coins.
After a short distribution In late 2025, LTH supply rebounded sharply, adding approximately 212,000 BTC within 30 days.
At the same time, the inactivity figures reinforce the tighter liquidity. About 61% of the total delivery has remained inactive for more than a year, gradually reducing its liquid trading inventory.

In the meantime, Exchange balances have fallen to 2.4 million BTC, reinforcing the growing illiquid supply structure. Institutional custody further reinforces this trend. Place ETFs now hold approximately $86 billion worth of BTC, equivalent to 6.3% of the total supply.

This absorption is in stark contrast to small issues. The network produces approximately 13,500 monthly, with large holders accumulating significantly more.
As the 20 million BTC milestone approaches, markets are increasingly anticipating future scarcity. Gradually, Bitcoin’s supply structure is changing from issuance-driven expansion to a dominated secondary market
Institutional accumulation is outpacing Bitcoin’s new supply
Bitcoin’s shrinking block rewards are changing supply dynamics as the network approaches a major scarcity milestone.
In the meantime, miners income fell to about $29 million per day, increasing the number of government bond liquidations to support operations. In early 2026, approximately 33,000 BTC were transferred to exchanges, highlighting liquidity pressures.

This demand increasingly exceeds the amount mined each month, gradually reducing the available supply.
As Bitcoin approaches 20 million coins mined, new issuance becomes negligible compared to existing liquidity.
Gradually, markets are starting to price Bitcoin’s fixed scarcity model earlier, amplifying long-term supply compression as investors anticipate future shortages and adjust their purchasing strategies accordingly.
Final summary
- Bitcoin [BTC] Supply compression is increasing as the accumulation of long-term holders and ETFs continues to grow beyond the approximately 13,500 BTC mined each month.
- Bitcoin approaching the 20 million mark highlights a structural shift where declining issuance reduces the supply of liquidity and strengthens the market’s pricing for long-term scarcity.
