If you’ve been in the crypto space for a while, you’ve probably heard that Bitcoin mining is dead—about a hundred times. Yet, here we are in 2025, and miners are still out there, solving complex puzzles, securing the network, and making money. So, what’s the deal?

Bitcoin mining is the backbone of the Bitcoin network. It’s how transactions are verified and added to the blockchain, ensuring that no one spends the same Bitcoin twice. Think of it as a massive, global competition where miners use specialized computers—ASICs (Application-Specific Integrated Circuits)—to solve incredibly difficult math problems. The first one to solve it gets rewarded with new Bitcoin, plus transaction fees from users. Increasing Bitcoin adoption, growing institutional investments, and the evolving role of transaction fees is now supplementing miner rewards. This post will give you a complete overview of what Bitcoin mining is and how it works.

What is Bitcoin Mining Summary

Bitcoin mining is the process of updating the ledger of Bitcoin transactions known as the blockchain. Mining is done by running extremely powerful computers called ASICs that race against other miners in an attempt to guess a specific number. The first miner to guess the number gets to update the ledger of transactions and also receives a reward of newly minted Bitcoins. The Bitcoin block reward was halved in April 2024 to 3.125 BTC. The next halving in 2028 will reduce the reward further to 1.5625 BTC.

Today, to be profitable, you need to invest heavily in Bitcoin mining hardware, cooling, and storage. In 2025, there are other ways to mine Bitcoin without owning hardware, but we will get to it in a bit. For now, just know that it’s not possible to mine Bitcoin profitably with a PC or a GPU at home. You can calculate your profitability using a Bitcoin mining calculator.

Here’s what you’ll need to do to get started with Bitcoin mining:

  • Calculate mining profitability
  • Get a Bitcoin miner
  • Get a Bitcoin wallet
  • Find a mining pool
  • Download a mining program
  • Start Mining!

Key Takeaways

  • Bitcoin mining secures the network by validating transactions and preventing double-spending.
  • Miners use ASIC hardware to solve cryptographic puzzles, earning Bitcoin rewards and transaction fees.
  • The Bitcoin block reward was halved to 3.125 BTC in 2024 and will drop further to 1.5625 BTC in 2028.
  • Mining profitability depends on electricity costs, hardware efficiency, and Bitcoin’s market price.
  • Bitcoin mining now also uses renewable energy, making it more sustainable than before.

What is Bitcoin Mining?

Bitcoin is a decentralized alternative to the banking system but people have several questions about BTC. This means that the system can operate and transfer funds from one account to the other without any central authority.

With a trusted central authority, transferring money is easy. Just tell the bank you want to remove $50 from your account and add it to someone else’s account. In this example, the bank has all the power because the bank is the only one that is allowed to update the ledger that holds the balances of everyone in the system.

Bitcoin, on the other hand, creates a system that has a decentralized ledger. It gives independent miners the ability to update the ledger without giving them too much power. What does Bitcoin mining mean? It is the process of using specialized computers to validate transactions, secure the Bitcoin network, and receive rewards in Bitcoin for performing this work.

How Does Cryptocurrency Mining Work

Anyone who wants to participate in updating the ledger of Bitcoin transactions, known as the blockchain, can do so. But how does crypto mining work? All you need is to guess a random number that solves an equation generated by the system.

Sounds simple, right?

Of course, this guessing is all done by your computer. The more powerful your computer is, the more guesses you can make in a second, increasing your chances of winning this game. If you manage to guess right, you earn bitcoins and get to write the “next page” of Bitcoin transactions on the blockchain.

The solution to the equation is very hard to achieve but very easy to validate. You can think of a Rubik’s cube as a good example for this (very hard to solve, but easy to see you’ve solved it).

The Bitcoin Mining Process in a Nutshell

Once your mining computer comes up with the right guess, your computer determines which pending transactions will be inserted in the next block of transactions on the blockchain. Compiling this block represents your moment of glory, as you’ve now become a temporary banker of Bitcoin who gets to update the Bitcoin transaction ledger. The block of transactions you’ve created, along with your solution, is sent to the whole network so other computers can validate it.

Each computer that validates your solution updates its copy of the Bitcoin transaction ledger with the transactions that you chose to include in the block. The system generates a fixed amount of Bitcoins (currently 6.25 ) and rewards them to you as compensation for the time and energy you spent solving the math problem.

Additionally, you get paid Bitcoin transaction fees that were attached to the transactions you inserted into the next block. All the transactions in the block you’ve just entered are now confirmed by the Bitcoin network and are virtually irreversible.

Bitcoin mining is like a giant lottery where computers race to solve a complex math puzzle every 10 minutes. The first to solve it gets to add a new block of transactions to the Bitcoin network and earns a reward—currently 3.125 BTC plus transaction fees. These puzzles are designed to be incredibly hard to solve but easy to verify, ensuring security and preventing fraud like double-spending (using the same Bitcoin twice). In the early days, anyone could mine Bitcoin with a regular computer, but now the difficulty is so high that miners use specialized machines (ASICs) that are expensive and power-hungry.
Bitcoin Subreddit

Here’s a two-minute video showing the process of blocks and confirmations.

So that’s Bitcoin mining in a nutshell.

It’s called mining because of the fact that this process helps “mine” new Bitcoins from the system. But if you think about it, the mining part is just a by-product of the transaction confirmation process. So the name is a bit misleading, since the main goal of mining is to maintain the ledger in a decentralized manner.

Since mining is based on a form of guessing, each time a different miner will guess the number and be granted the right to update the blockchain. Of course, the miners with more computing power will succeed more often, but due to the law of statistical probability, it’s highly unlikely that the same miner will succeed every time.

Bitcoin Mining difficulty

Now that you know what Bitcoin mining is, you might be thinking, “Cool! Free money! Where do I sign up?” Well, not so fast…

Satoshi Nakamoto, Bitcoin’s inventor, crafted the rules for mining in a way that the more mining power the network has, the harder it is to guess the answer to the mining math problem. So the difficulty of the mining process is actually self-adjusting to the accumulated mining power the network possesses.

If more miners join, it will get harder to solve the problem; if many of them drop off, it will get easier. This is known as mining difficulty.

Mining difficulty

Mining difficulty adjusts every 2016 blocks

Difficulty Adjustment

Difficulty is self-adjusting in order to create a steady flow of new Bitcoins into the system. In a sense, this was done to keep inflation in check. Mining difficulty is set so that, on average, a new block will be added every ten minutes (i.e., the number will be guessed every ten minutes on average).

Now, remember, this is on average. We can have two blocks being added minute after minute and then wait an hour for the next block. In the long run, this will even out to ten minutes on average.

The difficulty adjustment is done every 2016 blocks (every 2 weeks on average) retroactively. Meaning, every 2016 blocks the system looks back on the past 2016 blocks and calculates the average block time. If it’s under 10 minutes it will increase the difficulty, if it’s over 10 minutes it will lower it.

Bitcoin Mining Hardware

Before we jump into this section, it is important to note that ASIC miners have been the standard since 2013, and CPU, GPU, or FPGA mining is no longer relevant for profitable Bitcoin mining.

CPU mining

When Bitcoin first started out, there weren’t a lot of miners out there. In fact, Satoshi, the inventor of Bitcoin, and his friend Hal Finney were a couple of the only people mining Bitcoin back at the time with their own personal computers.

Using your CPU (central processing unit—your computer’s brain) was enough for mining Bitcoin back in 2009, since mining difficulty was very low. As Bitcoin started to catch on, people looked for more powerful mining solutions.

GPU mining

A GPU (graphics processing unit) is a special component added to computers to carry out more complex calculations. GPUs were originally intended to allow gamers to run computer games with intense graphics requirements.

Because of their architecture, GPUs became popular in the field of cryptography, and around 2011, people also started using them to mine Bitcoins. For reference, the mining power of one GPU equals that of around 30 CPUs.

GPUs were used for mining Bitcoin in the past

FPGA mining

FPGA is a piece of hardware that can be connected to a computer in order to run a set of calculations. They are just like GPUs but 3–100 times faster. The downside is that they’re harder to configure, which is why they weren’t as commonly used in mining as GPUs.

FPGAs are more efficient than GPUs for mining purposes

ASIC mining

Around 2013, a new breed of miner was introduced: the ASIC miner. ASIC stands for Application Specific Integrated Circuit. ASICs are pieces of hardware manufactured solely for the purpose of mining Bitcoin. Unlike GPUs, CPUs, and FPGAs, they couldn’t be used to do anything else. Their function was hardcoded into the machine.

Today, ASIC miners are the current mining standard. Bitcoin mining has become entirely ASIC-dominated, and mining with PCs or GPUs is not just unprofitable—it’s practically obsolete. Some early ASIC miners even appeared in the form of a USB, but they became obsolete rather quickly. Even though they started out in 2013, the technology quickly evolved, and new, more powerful miners were coming out every six months.

After about three years of this crazy technological race, we finally reached a technological barrier, and things started to cool down a bit. Since 2016, the pace at which new miners are released has slowed considerably.

Canaan CEO Nangeng Zhang sees Bitcoin mining evolving with efficiency gains, new energy sources, and AI integration. He predicts “over 20% efficiency gains per year” despite slowing ASIC advancements. He highlighted in an interview that the Middle East is a growing mining hub with “welcoming regulations.”

Difference Between ASICs and GPUs

ASIC miners generate significant heat and noise, often requiring industrial-scale cooling solutions, while GPUs are quieter and more versatile, making them easier to repurpose for gaming, AI, or other computing tasks. Companies, like Nvidia, are also investing in virtual GPUs. Here is how the two compares:

Parameter ASIC Miners GPU Miners
Initial Cost High ($3,000 – $10,000 per unit) Lower ($500 – $2,000 per unit)
Hash Rate Very High (TH/s range) Lower (MH/s range)
Energy Efficiency High (More hashes per watt)
Lower (Higher power consumption)
Power Usage 1,500W – 5,500W 200W – 1,200W per GPU
Mining Algorithms Limited (Algorithm-specific) Versatile (Supports multiple coins)
Flexibility Low (Dedicated to one coin type) High (Can switch between coins)
Longevity Becomes obsolete faster Lasts longer
Resale Value Lower (Hard to resell after updates) Higher (Used for gaming/AI)
Ease of Setup More complex (Cooling required) Easier to set up
Best Use Case Large-scale mining operations Small-scale or multi-coin mining

Bitcoin Mining Pools

Mining is an extremely competitive game. Even if you buy the best possible miner out there, you’re still at a huge disadvantage compared to professional Bitcoin mining farms. That’s why mining pools came into existence.

The idea is simple – miners group together to form a “pool”  so they can combine their mining power and compete more effectively. Once the pool manages to win the competition, the reward is spread out between the pool members depending on how much mining power each of them contributed.

This way, even small miners can join the mining game and have a chance of earning Bitcoin (though they get only a part of the reward).

Mining pool distribution

The market share of the most popular Bitcoin mining pools in 2020

Today there are over a dozen large pools that compete for the chance to mine Bitcoin and update the ledger. Since China banned Bitcoin mining in 2021, mining operations have shifted to North America, Kazakhstan, Russia, and the Middle East. The U.S. now leads in mining hashrate, with Texas being a major hub due to its cheap energy and mining-friendly policies.

Is Bitcoin Mining Profitable?

The short answer for some is “probably not”; Many ask, can you still mine bitcoin? The correct answer is “it depends on a lot of factors.” A report by Fidelity Digital noted that miners must constantly expand operations to remain competitive.

“Miners cannot afford to just maintain their position in the network. Instead, they must constantly push to acquire more hash rate as well as increase the efficiency of their hash rate, acquire lower-cost energy from cheaper sources, and expand their infrastructure,” the report added.

When calculating Bitcoin mining profitability, there are a lot of things you need to take into account. For instance, using a Bitmain S21 XP+ Hyd (500TH/s, 5500W) at an electricity rate of $0.10/kWh, mining costs would be $13.20 per day in electricity while generating approximately 0.00028 BTC per day. This means profitability is highly dependent on Bitcoin’s market price and electricity costs in your region.

Let’s break them down further.

Hashrate (how powerful is your miner)

A Hash is the mathematical problem the miner’s computer needs to solve. The hashrate refers to your miner’s performance (i.e., how many guesses your computer can make per second).

Hashrate can be measured in MH/s (mega hash = 1m hashes per second), GH/s (giga hash  = 1b per hashes second), TH/s (terra hash = 1t hashes per second), and even PH/s (peta hash = 1000t hashes per second).

Bitcoin Reward

The number of Bitcoins generated when a miner finds a solution (in other words “solves a block”). This number started at 50 bitcoins back in 2009, and it’s halved every 210,000 blocks (about four years). The current number of Bitcoins awarded per block is 3.125.

The last block-halving occurred in April 2024, and the next one will be in 2028. Once the halving occurs the reward will decrease to 1.5625 Bitcoin.

Electricity cost

Also known as “how many dollars are you paying per kilowatt to get electricity?”

You’ll need to find out your electricity rate in order to calculate profitability. This can usually be found on your monthly electricity bill. The reason this is important is that miners consume electricity, whether for powering up the miner or for cooling it down (these machines can get really hot and noisy).

Power consumption

Each miner consumes a different amount of energy. You’ll need to find out the exact power consumption of your miner before calculating profitability. This can be found easily with a quick search online. Power consumption is measured in watts.

Pool fees

If you’re mining through a mining pool, then the pool will take a certain percentage of your earnings for rendering their service. Generally, this would be somewhere around 2%.

Bitcoin’s price

Since no one knows what Bitcoin’s price will be in the future, it’s hard to predict whether Bitcoin mining will be profitable. If you are planning to convert your mined bitcoins to any other currency in the future, this variable will have a significant impact on profitability.

Difficulty increase per year

This is probably the most important and elusive variable of them all. The idea is that since no one can actually predict the rate of miners joining the network, neither can anyone predict how difficult it will be to mine in six weeks, six months, or six years from now.

In fact, in all the time Bitcoin has existed, its profitability has dropped only a handful of times—even at times when the price was relatively low.

The last two factors  (price and difficulty increase) are the reason no one will ever be able to give a 100% accurate answer to the question “is Bitcoin mining profitable?”

Once you have all of these variables at hand you can insert them into a Bitcoin mining calculator (as can be seen below) and get an estimate of how many Bitcoins you will earn each month. If you can’t get a positive result on the calculator, it probably means you don’t have the right conditions for mining to be profitable.

Step-by-Step Guide for Mining at Home

If you want to know how to get started in cryptocurrency mining, follow these steps to set up your first secure Bitcoin miner:

Step 1 – Calculate profitability

Before even starting out with Bitcoin mining, you need to do some research. The best way to do this, as we’ve discussed, is through the use of a Bitcoin mining calculator.

Bear in mind that mining costs money! If you don’t have a few thousand dollars to spare on the right miner, and if you don’t have access to cheap electricity, mining Bitcoin might not be for you.

Step 2 – Get a miner

Once you’re done with your calculations, it’s time to get your miner! Make sure to go over our Bitcoin mining hardware reviews to understand which miner is best for you, if you haven’t done it already in step 1. Here’s a list of the most popular miners around today:

arrow-left arrow-right

You can purchase mining hardware directly from the manufacturers or buy them on second-hand markets such as eBay or Amazon.

Step 3 – Get a Bitcoin wallet

You’ll need a Bitcoin wallet for your newly mined Bitcoin. Once you have a wallet, make sure to get your wallet address, it will be a long sequence of letters and numbers.

Each wallet has a different way of getting to the Bitcoin address, but most wallets are pretty straightforward about it. Notice that you’ll need your Bitcoin address and NOT your private key (which is like the secret password for your wallet).

Step 4 – Find a mining pool

When you join a mining pool, you’ll be given only part of the math problem to solve. The combined work of all of the miners in the pool will make the pool more likely to solve the original problem and earn the bitcoin reward and transaction fees. The profits will be spread out throughout the pool based on contribution.

Basically, you’ll make a more consistent amount of Bitcoins and will be more likely to receive a return on your investment.

When choosing which mining pool to join, make sure to ask the following questions:

  • What is the reward method? (Proportional/Pay Per Share/Score Based/PPLNS—more on that here)
  • What fee does the pool charge for mining and the withdrawal of funds?
  • How frequently does the pool find a block (i.e., how frequently do I get rewarded)?
  • How easy is it to withdraw funds?
  • What kind of stats does the pool provide?
  • How stable is the pool?

To answer most of these questions, you can use our Bitcoin mining pools review or this excellent post from BitcoinTalk. You can also find a complete comparison of mining pools in the Bitcoin wiki.

Once you are signed up with a pool, you’ll get a username and password for that specific pool, which you will use later on.

Step 5 – Get a mining program (also knowns as a client)

Controlling and monitoring your mining hardware requires dedicated software. Depending on what mining rig you have, you’ll need to find the right software.

Many mining pools have their own software, but some don’t. In case you’re not sure which mining software you need, you can find a list of Bitcoin mining software here. Also, if you want to compare different mining software, you can do it here.

Step 6 – Start mining!

Connect your miner to a power outlet and fire it up. Make sure to connect it to your computer as well (usually via USB), and open up your mining software. The first thing you’ll need to do is to enter your mining pool’s address, username, and password.

Once this is configured, you will start collections shares, which represent your part of the work in finding the next block. According to the pool you’ve chosen, you’ll be paid for your share of coins—just make sure that you enter your address in the required fields when signing up to the pool.

Pro-tip: If you’re looking for an easy way to earn small amounts of Bitcoin without mining, using a Bitcoin Faucet can be a great option. These websites reward users with Bitcoin for completing simple tasks.

Additional Types of Mining

Cloud Mining

Cloud mining allows users to participate in crypto mining without owning physical hardware. Cloud mining means that you do not buy a physical mining rig but rather rent computing power from a mining company and get paid according to how much mining power you own.

At first, this sounds like a really good idea, since you don’t have to go through all of the hassle of buying expensive equipment, storing it, cooling it, and monitoring it.

However, when you do the math it seems that most of these cloud mining sites aren’t profitable. Those that do seem profitable are usually scams that don’t even own any mining equipment; they’re just elaborate Ponzi schemes that will end up running away with your money.

If you still want to pursue this path, make sure to make the right calculations before handing over any funds. Also review the terms and conditions closely.

Some cloud mining services have no guarantee when you look at the platform a little closer. If you decide to try cloud mining, look for a cloud mining company with a guaranteed return on your investment like Coin Mining Farm. This platform has a liquidity pool to help protect your investment if the price of Bitcoin drops severely.

Mining on a Mobile Phone

Some mobile apps claim to mine Bitcoin on your phone. While in theory, this is possible, due to the low processing power phones have compared to ASIC miners, you’ll probably end up draining your phone’s battery much faster and make a very small fraction of Bitcoin in return.

The apps that allow this act as mining pools for mobile phones and distribute earnings according to how much work was done by each phone.

Remember, mining is possible with any old computer—it’s just not worth the electricity wasted on it because the slower the computer, the smaller the chances are of actually getting some kind of reward.

For reference, mining was demonstrated in theory on a 55-year-old computer some time ago by IBM—and the result was of course, that it’s not worth it.

Web mining

Somewhere around 2017, the concept of web mining or ‘cryptojacking’ was introduced. Simply put, web mining allows website owners to “hijack” visitors’ CPU power and use them to mine Bitcoin.

This means that a website owner can make use of thousands of “innocent” CPUs in order to gain profits. However, since mining Bitcoins isn’t really profitable with a CPU, most of the sites that utilize web mining mine Monero instead. Up until today, over 20,000 sites have been known to utilize web mining.

The concept of web mining is very controversial. From the site’s visitor perspective, someone is using their computer without consent to mine Bitcoins. In extreme cases, this can even harm the CPU due to overheating.

From the site owner’s perspective, web mining has become a new way to monetize websites without the need for the placement of annoying ads. Also, the site owner can control how much of the visitor’s CPU he wants to control in order to make sure he’s not abusing his hardware.

For more information about web mining, you can read this post.

To estimate mining profitability, you can use a Bitcoin Mining Calculator. This tool helps miners calculate expected earnings based on several factors.

Conclusion – Is Bitcoin Mining Worth It?

Mining profitability depends heavily on electricity costs. By 2025, Bitcoin price has seen levels that were never expected. However, post-2024 halving, the mining rewards are at 3.125 BTC. Mining remains profitable for large-scale operations with cheap electricity. Small-scale miners should carefully calculate costs before investing. Bitcoin has also been criticized for its intense energy use. It is worth noting that Bitcoin mining has increasingly moved toward sustainable energy sources, with many miners using hydroelectric, solar, and flared gas energy.

Now that you’ve finished this extensive read, you should be able to answer this question yourself. If you still have any questions, feel free to leave them in the comment section below. Happy mining!

Keep in mind that sometimes there might be better alternatives to Bitcoin mining in order to produce a higher return on your investment.

For example, depending on Bitcoin’s price, it might be more profitable to just buy Bitcoins instead of mining them. Another option would be to mine cryptocurrencies that can still be mined with GPUs, such as Ethereum, Monero, or Zcash. With platforms like CryptoTab, you can convert your browser (on your computer or phone) into a mining rig while still using your device as usual.
