As of June 28, 2025, the Bitcoin network continues its journey toward mining its final coins. Currently, a significant portion of the total Bitcoin supply has already been mined.

Current Status of Bitcoin Mining
As of late 2024, approximately 19.9 million bitcoins had been mined, leaving roughly 1.09 million to be minted. This means that about 95% of the total Bitcoin supply is already in circulation. The total supply is capped at 21 million.
The Scarcity Factor
The limited supply of Bitcoin (21 million) is a key feature driving its value. With only a small percentage remaining to be mined, scarcity fuels speculation and investment in this decentralized digital currency.
When Will the Last Bitcoin Be Mined?
Predicting the exact date is difficult. After Bitcoin’s price surge in 2021, with over 2.2 million BTC remaining, current estimates suggest the last Bitcoin will be mined sometime in the next century.
What Happens When All Bitcoins Are Mined?
Once all 21 million bitcoins are mined, miners will no longer receive block rewards. Instead, they will be compensated through transaction fees paid by users sending BTC transactions. These fees will incentivize miners to continue securing the network.
The Possibility of Code Modification
While the total amount of Bitcoins is currently fixed, there is a theoretical possibility to change that. The underlying code could be edited to increase the total supply limit, but it’s an unlikely scenario due to community consensus.
Remaining Bitcoins
There are approximately 1.18 million BTC left to mine, representing about 5.62% of the total supply. This highlights how close we are to reaching the maximum cap.
Mining Rate
On average, around 450 new Bitcoins are mined daily.
Factors Affecting Mining Speed
The rate at which Bitcoin is mined is not constant. It’s governed by the “halving” events, which occur approximately every four years. During a halving, the block reward given to miners is cut in half. This reduces the rate at which new bitcoins enter circulation. The most recent halving occurred in 2024, further decreasing the block reward and slowing down the mining process. Difficulty adjustments, which occur roughly every two weeks, also play a role. These adjustments ensure that blocks are mined at a consistent rate, regardless of the total computing power (hash rate) dedicated to the network.
The Future of Bitcoin Mining
As the block reward diminishes with each halving, the reliance on transaction fees will become increasingly important for miners’ profitability. This transition presents both challenges and opportunities. On one hand, higher transaction fees could make using Bitcoin more expensive. On the other hand, a robust fee market could ensure the long-term security and sustainability of the Bitcoin network, even after the last Bitcoin is mined. The future of Bitcoin mining will also be influenced by technological advancements, such as more efficient mining hardware and innovative mining strategies.
Implications of a Finite Supply
The fixed supply of Bitcoin is a core tenet of its value proposition. Unlike fiat currencies, which can be printed at will, Bitcoin’s scarcity provides a hedge against inflation and makes it an attractive store of value for some investors. As the remaining bitcoins become increasingly scarce, the competition to acquire them is likely to intensify, potentially driving up the price. However, it’s important to note that the value of Bitcoin is subject to market fluctuations and is not guaranteed to increase.
The question of how many bitcoins are left to mine is a reminder of Bitcoin’s inherent scarcity and the innovative mechanisms that govern its creation and distribution. While the final Bitcoin won’t be mined for many years, the gradual decrease in the block reward and the eventual transition to a fee-based system are shaping the future of the Bitcoin network. Understanding these dynamics is crucial for anyone interested in the long-term prospects of this groundbreaking digital currency.
