The Bitcoin network has crossed a historic threshold. At block height 940,000, mined by Foundry USA, the 20 millionth bitcoin entered circulation - meaning over 95% of all BTC that will ever exist is now accounted for.

The Final Stretch

Only about 1 million BTC remain to be created, and the protocol's halving mechanism ensures that process will stretch across more than a century. At the current block reward of 3.125 BTC (set after the April 2024 halving), miners produce roughly 450 new coins per day. That rate will halve again around 2028, and continue halving every four years until the final satoshi is mined around 2140.

Bitcoin's annualized supply inflation now sits below 1%, already lower than gold's estimated 1.5-2% annual supply growth. By the 2030s, new issuance will be negligible in practical terms.

Predictable by Design

The milestone highlights what makes Bitcoin's monetary policy unique: it is entirely transparent and mathematically enforced. No committee votes on issuance. No crisis can trigger an emergency expansion. The 21 million cap is hardcoded into the protocol and enforced by thousands of nodes worldwide.

As Kraken Chief Economist Thomas Perfumo noted: "No central authority concerning money has ever credibly committed to an absolute supply ceiling - because no central authority could be trusted to hold the line forever."

Market Response

Analysts expect limited short-term price impact since the milestone was long anticipated. Bitcoin was trading near $68,000 at the time, with spot ETFs absorbing $1.45 billion in net inflows over the previous five days. The real significance is structural: an asset class with a fixed, verifiable supply cap now has less than 5% of that supply left to issue.
