What Happens When All Bitcoins Are Mined?

By Gabriele Asaro | Created: September 28, 2025 | Last updated: September 28, 2025 | Read Time: 12 minutes

Key Highlights

Here’s what happens when the last bitcoin is mined:

  • The number of bitcoins is set at 21 million. This brings scarcity, which can change the value of bitcoin.
  • The last bitcoin should be mined around the year 2140. This is because of something called halving.
  • After the last bitcoin is mined, people will not create any new bitcoins.
  • Bitcoin miners will stop getting block rewards. They will make money from transaction fees only.
  • The bitcoin network will still run as usual. Miners will keep the blockchain safe by checking transactions.

Introduction

Have you ever thought about what will happen when the last bitcoin is mined? Bitcoin is the first and most known digital currency in the world. It has a hard supply limit. This means there can only ever be 21 million bitcoins in circulation. The idea of scarcity is at the heart of bitcoin’s plan.

One day, bitcoin mining will stop. When the last bitcoin has been mined, things will not be the same. The way this digital currency works is going to change for everyone. This blog post will talk about what might happen to bitcoin, mining, and the market once all bitcoins are out there.

What Happens Once All Bitcoin is Mined?

Once all bitcoins are mined, the maximum supply of 21 million coins will be reached. Miners will then rely on transaction fees for income instead of block rewards. This shift may impact network security and transaction processing speeds as the incentive structure changes within the Bitcoin ecosystem.

Understanding Bitcoin’s Supply Limit

The bitcoin protocol says that there can only be a maximum supply of 21 million coins of this digital currency. This supply limit stays fixed, and no one can make more than that amount. That is what sets bitcoin apart from fiat currencies, which some places can print as much as they want. This kind of scarcity is what brings value to bitcoin over a long time. People look at it for that reason.

But why did they pick this exact number of bitcoins for the maximum supply? And how long will it take to reach that limit? We can look into why there is a cap on the number of bitcoins. Plus, we can find out when the very last coin will be mined.

Why Is There a Maximum of 21 Million Bitcoins?

The maximum supply of bitcoin is set at 21 million. That number is written right into its code. The people who made bitcoin wanted to make it feel rare. This way is like how there is not a lot of gold in the world. They did this to make sure that bitcoin keeps its value. With a set amount, the value of bitcoin can be protected from rising prices and inflation. This rule is the reason for the scarcity of bitcoin.

Unlike money from central banks, which can lose its value when they print more, the number of bitcoins stays the same and is set. This means there will not be more bitcoin made after a limit is reached. Scarcity like this can help bitcoin to be a good store of value over time. This is one thing that makes this digital currency different.

As more people want to get bitcoin but there is a limited amount, this scarcity could push its price up. There are only 21 million bitcoins, and no more will be made. This makes bitcoin a digital asset with a fixed supply.

The Timeline to the Last Bitcoin Mined

The journey to mining the last bitcoin is set to take a long time. Experts think it will end around the year 2140. This long wait is because of a rule in the bitcoin protocol called "halving." About every four years, the reward miners get for finding a new block in the blockchain is cut in half. This way, miners get less bitcoin over time as they work on mining and adding each new block to the blockchain.

This halving happens to slow down how fast new bitcoins go into circulation. There have already been over 19.5 million bitcoins mined. Now, because people get less reward, the rest of the coins will take more time to be mined. The next halving will lower the reward even more. This will keep the same pattern going.

The mining process is set up to move slowly. This helps to keep the release of new coins steady over time. It also means that people can expect the rate of new coins being added for more than a hundred years.

The Role of Miners Before and After the Final Bitcoin

Bitcoin miners have a crucial role in keeping the network safe and running well. Right now, their mining operations are supported by mining rewards. These rewards include new bitcoins and transaction fees. This system helps bitcoin miners stay invested in mining and doing the work to check transactions. It also keeps the blockchain strong and safe.

Right now, miners make money by getting block rewards when they help confirm new bitcoin transactions. They work to add new blocks to the blockchain, and in return, they get some bitcoin as a reward. But after the final bitcoin is mined, these block rewards will stop. So, what will keep miners doing their work once there are no more new bitcoins to earn? The reason may change, but they may still get paid from transaction fees.

Let's look at how their job could be different and what drives them to keep going after the last bitcoin is made.

How Bitcoin Miners Currently Earn Rewards

Right now, bitcoin miners get paid in two ways. These rewards help make mining bitcoin worth it. The income is given to miners for using lots of power and energy in order to solve hard puzzles. These puzzles must be finished before a new block is added to the blockchain.

This dual-income model helps miners stay motivated to keep the network safe. The main way miners earn is through block rewards. These rewards are made up of new bitcoins that get created each time miners finish a block.

The current sources of mining rewards are:

  • Block Rewards: Every time miners add a new block to the blockchain, they get a set amount of new bitcoins. Right now, this block reward is 3.125 BTC for each new block.
  • Transaction Fees: Miners also get the mining fees that come with the transactions they put in a block. People pay these transaction fees, so miners can process their transactions during mining.

What Changes for Miners Once All Bitcoins Are Mined?

Once the final bitcoin is mined, there will be no new bitcoins made at all. The biggest change for miners is that block rewards will go away completely. Their way to do mining and mining operations will have to change a lot. That is because miners will not get any block rewards anymore. They will need to find some other way to keep their mining business going.

This change will make miners rely fully on a new way to earn money. They have to use this money to pay what they owe and make some profit. Now, the main goal for miners will be to get the fees that come from handling the transactions.

Here’s what will change for miners:

  • End of Block Rewards: The main reason miners get new bitcoins will go away. There will be no more block rewards.
  • Reliance on Transaction Fees: They will only get paid from the transaction fees. These are also called mining fees. People pay these fees to get their transactions in a block.
  • Prioritization of High-Fee Transactions: Miners will want to take transactions with higher fees first. This lets them earn more when they do mining.

Bitcoin Network Functionality Post-Final Bitcoin

A lot of people want to know if the bitcoin network will stop working once the last bitcoin is mined. The answer is no because this will not happen. The network is made to keep going even after all coins are mined. Mining will still be needed to make sure transactions are right and to keep the bitcoin blockchain safe. The bitcoin network and blockchain will stay strong as long as there are miners to do the work.

The main functions of the network will stay the same. But the ways people earn money from it will change.

So, how are transactions going to be checked? And will the network keep being safe if there are no new coins for people to earn?

How Will Transactions Be Verified After Mining Ends?

Even when the last bitcoin has been mined, the way the blockchain works will stay the same. The miners will still try to solve tough math puzzles for every block. The one who solves it first gets to add the next block of transactions to the blockchain. The steps for checking each transaction will be just like they are now.

The main bitcoin protocol for checking transactions has not changed. The only thing that is different is what the miners get in return for their hard work with bitcoin.

Miners will no longer get new bitcoins as a reward. They will get paid by the transaction fees from users. Here is how this will happen:

  • You will add a fee to your transactions.
  • Miners will bring these transactions together to make a block.
  • The miner who puts the block onto the blockchain will take all the fees that came from those transactions.

Will the Bitcoin Blockchain Remain Secure?

People often worry about network security when there is talk about the end of block rewards. The safety of the bitcoin blockchain is tied to the total hash rate. This means all the power that bitcoin miners use together to secure the bitcoin network. A high hash rate helps keep the network strong. It makes bitcoin hard to attack. When miners work well, it is good for the security of the blockchain.

The big question is if transaction fees are going to be enough for miners to keep the hardware running. People hope that when the network gets bigger, there will be more transactions and these will be worth more. Then, transaction fees could be a good and enough reward for miners.

Ongoing improvements in mining tools are helping the process use less energy and cost less money. This means miners can stay profitable even if they earn less now. It will keep them working on the mining, giving their computing power to keep network security strong and protect the blockchain.

Transaction Fees and Their Future Impact

As we know, transaction fees will be more important for miners once block rewards end. At that time, mining fees will go from being a secondary way for miners to earn money to the main source of their income. This change will make mining fees the main thing that keeps the mining industry running.

This change will impact both miners and people who use the network in a big way. Let’s look at how it might affect what miners do and how it could change things like transaction fees and how fast transactions go in the future.

Shifts in Miner Incentives After Block Rewards Cease

When block rewards stop, miners will focus on earning more from transaction fees. In this time, they will look at each transaction for the fee that comes with it. Miners want to make more money and will pick the ones that pay the most. They will look at transaction fees before adding different transactions.

This leads to a market the miners take part in when it comes to block space. In this market, if you want your crypto transaction to be finished fast, you have to pay a good fee for it. It works a lot like when people look for the lowest fee crypto exchange to keep more of their money while trading. The miners, on the other hand, try to find those transactions that come with the highest fees, since this helps them get the best profit.

The new incentives for miners will include:

  • Focus on Fee Maximization: Miners will try to pick transactions that offer the highest mining fees for their blocks. They do this to make the most from transaction fees during the mining process.
  • Competition for Block Space: People will want their transactions to go in first. This can make transaction fees go up when many want the same thing at one time.
  • Maintaining Profitability: The total transaction fees taken in by miners need to be enough. This helps to pay for things like hardware, electricity, and other costs that come from mining. It is important for their profitability.

Potential Effects on Transaction Costs and Speed

The move to a fee-only model can change both how much you pay and how fast it takes for your transaction to go through. When there is a lot of activity on the network, there can be higher fees. This is because more people try to get space in each block at the same time. If you need your transaction to finish fast, you may have to pay more.

This setup can make the fee market change often. The cost to send a transaction might go up or down, depending on how many people use it at the time. Because of this, the speed of your transaction can depend more on the fee you choose to pay. If you pay a low fee, your transaction could take more time to be finished.

The bitcoin ecosystem keeps changing all the time. Layer 2 solutions, like the Lightning Network, help with these problems. They let people make faster and cheaper transactions, instead of using only the main blockchain. The use of these technologies will play a crucial role in dealing with higher fees. This makes sure bitcoin stays useful for people every day.

Frequently Asked Questions (FAQ)

Curiosity about what happens to bitcoin in the future is still strong. A lot of people ask what will happen when bitcoin hits its maximum supply. When no new bitcoins can be made, they want to know how this might change bitcoin’s value. As it gets harder to get new bitcoins, people also ask if transaction fees will go up and if higher fees will make a difference for network security.

People are thinking about how miners will keep making a profit with mining rewards going down over time. This is something both old and new bitcoin miners want to know about, because it can be hard to keep your crypto mining business going if you do not earn enough. If you are looking into the best places to do crypto trading, you may want to check out this lowest fee crypto exchange.

Is Bitcoin Mining Still Profitable After All Coins Are Mined?

Yes, bitcoin mining can still make money after the last coin is found. The way bitcoin miners earn will be based only on transaction fees. If the money from these fees is high enough for miners to pay for things like electricity and tools, then mining will still make sense. The profitability of mining will depend on these costs and fees. Bitcoin miners need to make sure that they get enough from transaction fees to keep mining going.

Could Bitcoin’s Scarcity Affect Its Price in the Future?

Bitcoin is rare because there is a maximum supply of just 21 million coins. This is a key thing about bitcoin and could help its price go up. If more people want bitcoin or if the same number of people want it while the supply stays fixed, there will be upward pressure on the value of bitcoin. This is different from the dollar, which can lose value over time because more of it gets made.

The scarcity of bitcoin may make it a better choice for some people.

What Are the Alternatives for Miners After All Bitcoins Are Mined?

Miners might not always need new options if the mining process keeps giving them profit with transaction fees. They will then look for ways to make mining operations work better. This can mean searching for cheaper energy sources or getting hardware that uses less energy. Some may also start to use renewable energy sources. These steps help them cut costs and stay ahead in a market that is based on transaction fees.

Conclusion

Understanding what happens when all bitcoin is mined is important for anyone who has put money into cryptocurrency. When that moment comes, the mining process will change a lot. The bitcoin network will still work and find new ways to move forward. Miners will move away from making money from block rewards.

Instead, they will focus more on earning by collecting transaction fees. This will change how transactions on the bitcoin network get verified and will shape the future of bitcoin's economy. As the world of cryptocurrency grows and changes, it is smart to keep up with these facts to help you make better choices when you invest.
