As of June 18, 2025, Bitcoin operates with a fixed supply, capped at 21 million coins. This scarcity is a fundamental aspect of its design.

Bitcoins in Circulation
Currently, approximately 19.96 million Bitcoins have already been mined and are in circulation. This leaves a limited number of coins still available to be mined.
Bitcoins Left to Mine
With a total supply of 21 million, roughly 1.04 million Bitcoins remain to be mined. The rate at which these coins are released is governed by Bitcoin’s mining process.
The Mining Process
New Bitcoins are created through a process called mining. Miners verify and add transaction data to the blockchain, receiving Bitcoin as a reward.
Halving Events
To control inflation, Bitcoin implements “halving” events approximately every four years. These events reduce the block reward given to miners, slowing down the rate at which new Bitcoins are created.
Bitcoin Millionaires
Due to Bitcoin’s price appreciation, many individuals have accumulated significant wealth; A 2024 study estimated over 85,000 Bitcoin millionaires.
The Final Bitcoin
Due to the halving mechanism, the mining reward diminishes over time. Predictions estimate that the last Bitcoin will be mined around the year 2140. After this point, miners will primarily earn revenue from transaction fees.
Daily Bitcoin Creation
On average, 144 blocks are mined per day, with each block currently yielding 6.25 Bitcoin. This results in approximately 900 new Bitcoins being mined daily (144 x 6.25 = 900). This rate will decrease at the next halving event.
Bitcoin’s Scarcity and Value
Bitcoin’s limited supply is a key factor contributing to its perceived value. Unlike traditional currencies, which can be printed at will by central banks, Bitcoin’s scarcity is hardcoded into its protocol. This scarcity, combined with increasing adoption, drives demand and potentially influences its price.
Understanding Bitcoin’s Supply
Understanding the total supply, circulating supply, and the mining process is crucial for anyone interested in Bitcoin. These factors play a significant role in its economics and long-term viability. The controlled release and eventual cap on the number of Bitcoins distinguish it from many other digital assets.
Beyond the Numbers
While knowing the number of Bitcoins is important, it’s equally vital to understand the underlying technology, the network’s security, and the growing ecosystem surrounding Bitcoin. Its decentralized nature and cryptographic security are key attributes that contribute to its unique value proposition.
The Future of Bitcoin Supply
As we approach the year 2140 and the mining of the final Bitcoin, the network dynamics will shift. Miners will become increasingly reliant on transaction fees to sustain their operations. This transition is a critical aspect of Bitcoin’s long-term sustainability and security.
Transaction Fees: A Vital Component
Transaction fees are small amounts paid by users to prioritize their transactions and incentivize miners to include them in a block. As block rewards decrease, these fees will become the primary source of income for miners, ensuring the network’s continued operation.
The Impact of Lost Bitcoins
It’s important to note that a significant number of Bitcoins are estimated to be lost forever due to forgotten private keys, lost hard drives, or other mishaps. This effectively reduces the actual circulating supply below the theoretical maximum of 21 million, potentially increasing the scarcity of accessible Bitcoin.
Bitcoin’s Divisibility
Although there are only 21 million Bitcoins, each Bitcoin is divisible into smaller units called “satoshis.” One Bitcoin is equal to 100 million satoshis. This divisibility allows for even small transactions and ensures the network can accommodate a large number of users.
Beyond Investment: Bitcoin’s Utility
While Bitcoin is often seen as an investment, it’s also a functional currency and a platform for innovation. Its decentralized nature and permissionless access make it a valuable tool for individuals and businesses seeking greater financial autonomy and control.
The Evolving Bitcoin Ecosystem
The Bitcoin ecosystem is constantly evolving, with new applications and services being developed on top of the Bitcoin blockchain. These innovations are expanding Bitcoin’s utility and attracting new users to the network.
Staying Informed
Keeping up-to-date with the latest developments in the Bitcoin world is crucial for anyone interested in this technology. Following reputable news sources, participating in online communities, and researching the underlying technology are all essential steps in understanding Bitcoin’s potential and risks.
The limited supply of Bitcoin, coupled with its increasing adoption and evolving ecosystem, makes it a unique and potentially transformative technology. Understanding the dynamics of its supply, mining process, and economic incentives is essential for navigating the world of Bitcoin and appreciating its long-term prospects.
