Bitcoin officially reaches 20 million units: The 100-year countdown begins

The Bitcoin network reached 20.000.000 units issued at block height 940.000.

According to blockchain data, the circulating supply of bitcoins has officially reached 20.000.000 units. This milestone reduces the margin for future issuance to less than 1.000.000 BTC, which will be distributed in decreasing amounts over the next 114 years, approximately. 

The validation of block number 940.000, which gave rise to this unit of BTC, closes an accelerated issuance cycle that began in 2009, placing the network in a stage of maturity where the supply available in the primary market will become increasingly scarce. 

The global accounting ledger of the network, distributed across thousands of nodes worldwide, confirms that 95,23% of the total supply of BTC has already been mined, leaving a minimal fraction to be contested by the digital mining industry in the 21st and early 22nd centuries. This milestone occurs within a context of institutional consolidation of the asset globally.

The protocol of the century: 17 years for 20 million and 114 years for the last million

The design of Bitcoin, established in its original protocol by Satoshi Nakamoto, dictates a maximum limit of 21.000.000 units. 

The speed at which the first 20.000.000 BTC were generated is due to an issuance mechanism that started with 50 BTC per block and is halved every 210.000 blocks, a process known as «halving", which occurs approximately every 4 years. 

Since the network's inception in January 2009, it has taken approximately 17 years to reach this figure of 20 million units. The blockchain protocol's architecture is programmed so that the mining difficulty adjusts every 2.016 blocks, ensuring that the issuance of new BTC is predictable and independent of the will of central entities.

Now, based on the design rules of the Bitcoin protocol, experts point out that the issuance and distribution of the remaining million coins will follow a much slower timeline due to the progressive reduction of the block reward. In other words, while the first 20.000.000 BTC were mined in less than two decades, the last million bitcoins will require more than a century to be mined from the blockchain network. 

According to technical projections based on an average block time of 10 minutes, The last bitcoin will be mined around the year 2140.This temporal asymmetry is the product of a deflationary emission algorithm that seeks to mimic the extraction of finite natural resources, where obtaining the last units requires an exponentially greater deployment of energy and time than at the beginning.

The community celebrates digital scarcity

The milestone of 20.000.000 BTC mined has generated coordinated reactions among major players in the financial market and high-profile figures. 

Through its official channels, Fidelity's digital asset division highlighted the importance of this event for the scarcity thesis of the leading cryptocurrency by market capitalization. The firm indicated that reaching the "20 million" phase underscores the immutability of the network's monetary policy, a factor that institutions value when evaluating blockchain infrastructure. 

For his part, businessman Ricardo Salinas Pliego highlighted the importance of owning a fraction of a supply that is now officially more limited, emphasizing that the 20.000.000 barrier is a reminder of the finite nature of the technological tool.

Salinas highlighted Bitcoin's potential and reaffirmed his confidence in the cryptocurrency, noting that there will only ever be 21 million of them and that this digital scarcity is what makes Bitcoin so special. the best form of “hard” moneyHe emphasized that Bitcoin's rules are written in code and no one can change them. Therefore, "no one can print more Bitcoin" whenever or for any reason, he stated. 

On the other hand, the crypto community has also registered the recent event as a successful test. Since its launch, the Bitcoin network has managed to maintain its usual pace without significant interruptions and with perfectly verified transactions. For developers and validators, this performance confirms that the protocol continues to function with the same precision for which it was designed, even in the face of the ever-expanding user base and the computing power that supports each block of data on the chain.

Bitcoin's maturity: less supply and more conviction

From a financial perspective, Bitcoin is currently trading under a correction dynamic after reaching all-time highs in October 2025. Despite this price decline from the peaks of late last year, market analyst reports suggest that investors with a long-term horizon are maintaining their positions. 

The focus of these forks is not on short-term BTC fluctuations, but on the fundamental properties that the 20.000.000 mined unit milestone highlights: the absolute scarcity and inability to increase supply above what is stipulated in the source code.

Digital asset experts agree that Bitcoin's technical advantage lies in its transparency. Anyone with an internet connection can verify that fewer than 1.000.000 units remain to be issued. This mathematical certainty contrasts sharply with other systems where the total supply is unknown or subject to discretionary changes. 

In a global market where digitalization is advancing, the concept of digital scarcity is solidifying as the central focus for those who consider blockchain technology a final settlement infrastructure. At the same time, the availability of cryptocurrency on trading platforms is decreasing, while storage in wallets under the direct control of their owners is increasing, reinforcing the feeling that the most sought-after resource in the market is also the most limited.
