Bitcoin’s Supply Squeeze Deepens as Issuance Falls to Historic Low

Bitcoin’s march toward full issuance has reached a new landmark.

On Monday, the network quietly pushed past 19.95 million mined coins, leaving less than 5% of its eventual supply still to be created – a reminder of how quickly Bitcoin is approaching the phase where new issuance becomes almost negligible.

Only a little over 1 million BTC remain to be mined, and the pace at which they will arrive is slowing dramatically. With each halving cutting miner rewards in half roughly every four years, the trickle of new coins narrows until it eventually fades out completely. The final fractions aren’t expected until sometime around 2140, long after block subsidies become a historical footnote and transaction fees form the backbone of miner revenue.

A small portion of Bitcoin’s supply – around 230 BTC – can never move at all due to early technical quirks and unspendable outputs. And that figure doesn’t include the far larger trove believed to be lost forever through misplaced keys, abandoned wallets, and early-era accidents.

A Monetary System Designed to Tighten Over Time

Halvings have already compressed Bitcoin’s inflation rate to below 1%, a level reached after the April 2024 reward cut dropped the subsidy from 6.25 BTC to 3.125 BTC per block. Earlier cycles followed the same pattern: 50 → 25 BTC in 2012, 25 → 12.5 BTC in 2016, and 12.5 → 6.25 BTC in 2020. The next event, currently projected for April 2028, will again slice issuance in half.

This engineered scarcity is what many economists point to when explaining Bitcoin’s resilience as a long-term asset. Kraken’s Thomas Perfumo argues that the network’s fixed supply and predictable issuance stand in contrast to traditional money systems, where supply can expand rapidly in response to political or economic pressures.

Short-Term Noise, Long-Term Design

Perfumo notes that Bitcoin’s price will always react to cycles – liquidity changes, macro shocks, shifting investor sentiment – but over longer horizons, the asset’s rigid supply curve acts as an anchor for value. As adoption rises and regulation matures, Bitcoin is increasingly treated not as a speculative trade but as a structural component of diversified portfolios.

With nearly all of its coins already created and the remainder set to arrive painfully slowly, Bitcoin’s scarcity story is no longer theoretical – it’s unfolding in real time.
