How Many Bitcoins Are Left to Mine?

In summary, approximately 1.6 million Bitcoins are yet to be mined. The total supply of Bitcoin is 21 million.

In the world of cryptocurrencies, Bitcoin has gained significant popularity and has become a household name. As the first decentralized digital currency, Bitcoin has revolutionized the way we perceive and transact value.

However, there is one question that often arises among crypto enthusiasts and newcomers alike: “How many Bitcoins are left to mine?

In this article, we will delve into the intricacies of Bitcoin mining and explore the current state of the remaining Bitcoin supply.

How Many Bitcoins Are Left to Mine?

How Many Bitcoins Are Left to Mine?

Bitcoin is designed to have a limited supply, with a total of 21 million coins that can ever be mined. This scarcity is a fundamental aspect of Bitcoin’s value proposition, as it ensures that the cryptocurrency remains deflationary in nature.

So far, a significant portion of the total Bitcoin supply has already been mined, with over 19.4 million Bitcoins in circulation as of the time of writing. This leaves approximately 1.6 million Bitcoins yet to be mined.

The Bitcoin Halving Event

To understand the rate at which Bitcoins are being mined, we need to consider the concept of the Bitcoin halving event. Approximately every four years, the Bitcoin network undergoes a halving event, which reduces the block reward for miners by half. Initially, when Bitcoin was created in 2009, the block reward was set at 50 Bitcoins. However, due to the halving events, the block reward has decreased over time.

The first halving event occurred in 2012, reducing the block reward to 25 Bitcoins. The second halving event took place in 2016, further reducing the block reward to 12.5 Bitcoins.

The most recent halving event occurred in May 2020, cutting the block reward in half once again to its current rate of 6.25 Bitcoins. These halving events serve as important milestones in the Bitcoin mining process and have a direct impact on the rate at which new Bitcoins are generated.

The Mining Process and Block Rewards

Bitcoin mining involves the use of powerful computers to solve complex mathematical problems that validate transactions on the network. Miners compete with each other to find the solution to these problems, and the first miner to solve it successfully is rewarded with newly minted Bitcoins. This reward serves as an incentive for miners to contribute their computational power and secure the Bitcoin network.

With each block mined, a certain number of Bitcoins are created and awarded to the miner. This is known as the block reward. In addition to the block reward, miners also receive transaction fees associated with the transactions included in the block. As the Bitcoin network matures and transaction volumes increase, transaction fees have become an increasingly important component of miner revenue.

Factors Affecting Bitcoin Mining

Several factors influence the rate at which new Bitcoins are mined. Firstly, the difficulty of the mathematical problems that miners must solve adjusts approximately every two weeks. This adjustment ensures that blocks are mined, on average, every 10 minutes. If the computational power of the network increases, the difficulty will increase as well, maintaining the desired block time.

Secondly, the cost of electricity and the efficiency of mining hardware play a significant role in Bitcoin mining. As the network’s difficulty increases, miners need more powerful and energy-efficient hardware to remain competitive. High electricity costs can eat into miners’ profits, making it essential to consider these factors when engaging in Bitcoin mining operations.

Frequently Asked Questions (FAQs)

1. How many Bitcoins are mined per day?

On average, the Bitcoin network produces approximately 900 new Bitcoins per

day. This number is subject to change due to the block reward halving events and fluctuations in network difficulty. It’s important to note that the number of Bitcoins mined per day will continue to decrease over time as we approach the total supply cap of 21 million.

2. When will all the Bitcoins be mined?

Based on the current rate of block production and the remaining supply, it is estimated that all 21 million Bitcoins will be mined by the year 2140. However, it’s important to remember that this is just an estimate and is subject to various factors, including changes in mining technology and network dynamics.

3. Can Bitcoin mining be profitable?

Bitcoin mining can be profitable, but it depends on several factors such as the cost of electricity, mining hardware efficiency, and the current Bitcoin price. As the mining difficulty increases, it becomes more challenging to mine new Bitcoins, which can impact profitability. It’s crucial for miners to carefully consider these factors and stay informed about market conditions.

4. What happens when all the Bitcoins are mined?

Once all 21 million Bitcoins have been mined, no new Bitcoins will be created through mining. Miners will rely solely on transaction fees as their source of income. This transition is expected to occur gradually over time as the block reward diminishes. It’s worth noting that transaction fees are already an essential part of miner revenue and will likely become even more significant in the future.

5. Is it too late to start mining Bitcoin?

While it’s true that Bitcoin mining has become more competitive over the years, it is still possible to enter the mining industry. However, it’s important to consider factors such as upfront investment costs, electricity expenses, and mining profitability. Many miners today join mining pools to increase their chances of earning rewards. Additionally, there are alternative cryptocurrencies that can be mined with less competition.

6. What happens if no one mines Bitcoin?

The security and functionality of the Bitcoin network rely on miners. If no one mines Bitcoin, the network would become vulnerable to attacks and would cease to function effectively. However, the incentives built into the Bitcoin protocol encourage miners to participate in the network and validate transactions. As long as there is value in Bitcoin and a community of miners, the network is likely to continue operating.


Bitcoin mining plays a crucial role in the creation and maintenance of the Bitcoin network. With a limited supply of 21 million coins, the question of how many Bitcoins are left to mine becomes increasingly relevant.
