Bitcoin Makes History with the Mining of the 20 Millionth Coin

Bitcoin has reached a historic milestone, with miners successfully producing the 20 millionth coin—a significant marker integrated into the protocol by Satoshi Nakamoto nearly 20 years ago.

Key Takeaways

The Bitcoin network has reached the milestone of 20 million coins mined as of March 9, 2026, after 17 years, 2 months, and one week since the first block was mined in January 2009.
Over 95% of Bitcoin's capped supply of 21 million coins is now in circulation; however, many coins are inaccessible due to lost passwords, unclaimed private keys, and other factors.
The remaining supply of Bitcoin will take approximately 114 years to fully mine, with various halvings reducing rewards over time, raising concerns for miners' income sustainability.
Bitcoin’s price has faced volatility, currently at $69,282, down 20.84% year-to-date, amid broader market fluctuations.

The Foundry USA mining pool was instrumental in this achievement, mining the Bitcoin at block height 939,999 and earning a block subsidy reward of 3.125 BTC, which is the post-April 2024 halving reward level.

Bitcoin Reaches the 20 Millionth Coin Milestone

According to on-chain data from CloverPool, the 20 millionth Bitcoin was mined today, March 9, 2026. This achievement reflects a lengthy timeline since the first block was mined in January 2009, taking precisely 17 years, 2 months, and one week to hit this milestone.

This milestone indicates that more than 95.24% of Bitcoin's maximum supply of 21 million coins is currently circulating in the market. To put this in context, for every 20 Bitcoins that have been created, there remains only one left to be mined.

Bitcoin’s Diminishing Supply and Lost Coins

It's crucial to note that not all of the 20 million Bitcoins mined are accessible to their respective owners. Blockchain analytics companies like River Financial and Chainalysis estimate that between 2.3 million and 3.7 million BTC are permanently unreachable, due to issues like forgotten passwords, lost private keys, deceased owners, or coins sent to inaccessible addresses.

Furthermore, estimates from Fortune suggest that around 1.8 million Bitcoins—approximately 8.5% of the total supply—are permanently lost, primarily from Bitcoin's initial years when it held little financial value and there was inadequate infrastructure for safe storage.

Additionally, 230.09 BTC remains unreachable due to the original genesis block subsidy and other early outputs with technical scripts that prevent their spending.

These insights reveal that the actual amount of Bitcoin available for use and trade today is significantly less than the prestigious figure of 20 million would imply.

Future Prospects for Bitcoin and Its Miners

Satoshi Nakamoto established Bitcoin's supply schedule from the software's inception, starting miners off with a reward of 50 BTC per block in 2009, halving that reward every 210,000 blocks—or approximately every four years. The most recent halving took place on April 20, 2024, which reduced the reward from 6.25 BTC to 3.125 BTC, consequently cutting daily production from 900 BTC to around 450 BTC.

The next halving is scheduled for April 11, 2028, at which point the reward will decrease further to 1.5625 BTC per block. The remaining 1 million Bitcoins will take approximately 114 years to fully mine, with the last fractions expected to be issued around the year 2140. The final complete Bitcoin could be mined in the 2090s, with the last satoshi—Bitcoin’s smallest unit—following many years later.

As the supply becomes more constrained, Bitcoin miners may face increasing challenges. By the 2040s, daily Bitcoin issuance is projected to fall below 30 BTC, and by the 2060s, it could drop below 2 BTC each day. With block subsidies nearing extinction in the future, transaction fees may become miners' sole source of income to maintain network security, raising questions about whether that income will be adequate for effective network protection.

Market Context Surrounding This Milestone

Bitcoin achieved this historic supply milestone amidst a backdrop of market instability, as the crypto landscape continues to react to macroeconomic and geopolitical developments, including the tensions from the Israel-Iran conflict.

Currently trading at around $69,282, Bitcoin has seen a decline of 20.84% year-to-date, following a slight 6.3% drop last year. However, recent performance indicates a possible easing of this downturn, with Bitcoin gaining 3.44% this week despite ongoing unrest in the Middle East.
