Only 1 Million Bitcoins Left: Coinbase CEO Describes BTC as ‘Decentralized, Inflation-Proof Money’

Summary:
The Bitcoin network has crossed the significant milestone of 20 million BTC mined, prompting Coinbase CEO Brian Armstrong to underscore Bitcoin's scarcity and its role as a “decentralized, inflation-resistant global currency.” With only approximately one million Bitcoins left to mine, Armstrong emphasizes Bitcoin’s unique design and the potential for gradual supply reduction over decades.

Key Takeaways

The Bitcoin network has mined over 20 million BTC, approaching its maximum supply cap of 21 million.
The final one million Bitcoins are expected to take over a century to be mined.
Bitcoin's supply issuance is designed to slow through a process called halving, where mining rewards decrease approximately every four years.
The last Bitcoin is anticipated to be mined around the year 2140.
Not all mined Bitcoins are accessible; some are permanently unspendable due to various reasons, including lost keys.

Bitcoin Supply Reaches 20 Million

Recent blockchain records reveal that Bitcoin has surpassed the milestone of 20 million BTC mined, specifically occurring at block height 939,999. Data from Mempool indicates that this block was mined by the Foundry USA mining pool. This significant event underscores how much of Bitcoin's total supply is already in circulation, with over 95% of its total with a hard cap of 21 million BTC already issued by November.

Upon reaching this milestone, the block reward was set at 3.125 BTC, a designated incentive for miners who validate transactions and generate new blocks on the blockchain.

Coinbase CEO Emphasizes Bitcoin’s Scarcity

Following the milestone announcement, Brian Armstrong, CEO of Coinbase, took to the social platform X to discuss the implications. He pointed out that with 20 million Bitcoins mined, only around one million remain to be created. Armstrong forecasted that it could take well over a century to mint this last segment of Bitcoin supply. He also highlighted Bitcoin's design as a decentralized monetary system that is built to withstand inflation and function without centralized control.

Supply Issuance Diminishes With Each Halving

The structure of Bitcoin's long-term supply was originally established by its mysterious creator, Satoshi Nakamoto, who set a hard cap of 21 million coins. New Bitcoins enter the market through mining rewards that incentivize miners to secure the network by validating transactions.

However, these rewards are not fixed; they decrease over time. When Bitcoin first launched in 2009, miners received 50 BTC for each block mined. This block reward is halved roughly every four years or 210,000 blocks. The most recent halving occurred on April 20, 2024, reducing the reward from 6.25 BTC to 3.125 BTC.

As a result, the introduction of new Bitcoins into the market has significantly slowed, with miners now generating about 450 BTC daily compared to the previous rate. Additionally, miners earn transaction fees associated with each block. The next halving is projected for April 11, 2028.

Final Bitcoin Expected to Be Mined Around 2140

Due to the halving effect, Bitcoin's supply will expand at a continually diminishing rate. While it took approximately 17 years to mine the first 20 million BTC, the remaining one million coins will be issued much more slowly. Current projections indicate that the last fractions of Bitcoin, termed satoshis, will continue to be mined until about 2140 when the supply limit will be reached. By that time, miners will depend primarily on transaction fees for revenue, since block rewards will have nearly vanished.

Some Bitcoins Are Permanently Unspendable

Importantly, not every mined Bitcoin can be spent. Blockchain records show that around 230.09 BTC are permanently unspendable. These include funds from the original genesis block reward and certain outputs created by scripts that make spending impossible. Furthermore, the total count of BTC does not reflect those that holders may have lost due to misplaced private keys, suggesting the number of usable Bitcoins might actually be lower than the total mined supply.
