What Is Cryptocurrency Mining, and How Does It Work in 2026?

What Is Cryptocurrency Mining in Simple Terms?

Mining is a process where thousands of individual computers support the secure operation of the blockchain and help execute crypto transactions.

How does blockchain work, and what is the role of miners?

Blockchain is an electronic ledger that records all cryptocurrency transactions. It is not stored on a single server: copies are distributed among many computers worldwide.

Miners are network participants who use their equipment to verify transactions, combine them into blocks, and add them to the blockchain. The network pays them a reward in cryptocurrency for this work. This is how data is verified, and the system continues to operate without central control.

Mining is used only in cryptocurrencies that use the Proof of Work algorithm. The most famous example is Bitcoin. Dogecoin, Litecoin, Monero, Kaspa, Bitcoin Cash, and other projects also use mining. 

Why is mining necessary?

There are at least three key tasks that cryptocurrency mining performs:

1. Verification of transactions. Miners examine every crypto transaction. The goal is to ensure that the sender actually has the correct amount and that the same crypto coins are not spent twice. After that, the transactions are combined into a block and permanently added to the blockchain. This guarantees protection against fraud and data falsification.
2. Support for decentralization. Unlike banking systems, blockchain does not depend on a single server, company, or state. It is supported by thousands of independent miners around the world, and even if some of them go offline, the network will continue to function because it will be supported by other participants.
3. New coins entering circulation. When a miner adds a new block, the network rewards them with cryptocurrency, which enters circulation. 

How Does Cryptocurrency Mining Work?

Understanding what cryptocurrency mining is will allow you to navigate the crypto market with more confidence and make more informed financial decisions, even if you don't plan to mine crypto coins yourself.

The mining process: step by step

Let's find out how cryptocurrency mining works using Bitcoin as an example.

1. Sending transfers. BTC transactions performed by users enter the network and await confirmation.
2. Collecting transactions by miners. Network participants collect new transactions into a single list — the future block. Only valid transactions with sufficient balance, and no attempts at fraud are included.
3. Searching for a solution. Miners use special equipment to search through possible answers to a cryptographic problem. Simply put, they try to be the first to find the right number that will allow them to create a new block. This process requires a lot of computing power and works on a competitive basis.
4. Creation of a new block. It is formed by the miner who was the first to find the correct solution. The block contains confirmed transactions and technical data linking it to the previous one in the chain.
5. Network verification. Other participants verify the new block for correctness. If there are no errors, it is added to the blockchain.
6. Reward. For a successfully created block, the miner receives 3.125 BTC (as of 2026) and commissions for transactions within the block. This is the main incentive to participate in mining.

Hash rate and network difficulty

The hash rate is an indicator of how powerful the entire network of miners is. It can be represented as the total "power" of all computers that are simultaneously trying to mine a new block. The more miners are connected, the higher the hash rate.

The network can automatically complicate and simplify tasks for miners. This is necessary to maintain balance when the power indicator rises or falls sharply. Difficulty directly affects the profitability of mining. If it is high, participants need more powerful equipment and more electricity, which increases costs. If the difficulty decreases, it becomes easier and cheaper to mine coins.

Thus, the hash rate shows how much "power" the network has, and the difficulty determines how hard it is for miners to get a reward. Together, these parameters support the stable operation of the blockchain and control the issuance of new coins.

Main Types of Mining

In this section, we will look at the main methods of mining cryptocurrency and the types of mining equipment.

ASIC

These are exclusively mining devices that have high power and relatively low energy consumption. Most often, ASICs are used to mine Bitcoin and other cryptocurrencies with high network complexity.

GPU

GPUs (graphics cards) are primarily designed for processing graphics, games, video, and 3D graphics. However, due to their high computing power, they are also used for mining. 

GPUs are well-suited for performing multiple parallel calculations and allow you to switch between different cryptocurrencies. At the same time, graphics cards are less efficient than ASICs.

CPU

These are ordinary computer central processing units that perform everyday tasks. Mining on a CPU is also possible, but it was more relevant in the early stages of cryptocurrency development, when there was minimal competition on the networks. Today, CPU power is insufficient for mining the most popular coins, so this option is rarely used, mainly for niche crypto projects.

Cloud mining

This method allows you to earn money from mining cryptocurrency without purchasing your own equipment. The user rents computing power in specialized data centers and pays for their maintenance. Cloud mining is a simpler and more affordable option for beginners.

How to Start Mining Cryptocurrency from Scratch?

Crypto mining requires certain technical knowledge and equipment, but almost any user can master it if they want to. We have prepared a guide on how to start mining cryptocurrency from scratch for beginners, which will help you take your first steps.

Requirements and equipment

In 2026, mining is no longer a "home experiment" but a calculated technical process. It is important to understand the basic requirements for equipment and operating conditions:

1. Decide what equipment you will use to mine crypto: ASIC, GPU, or CPU. Then download the necessary software to your computer.
2. Consider how much money you are willing to spend on electricity. The equipment runs around the clock and consumes a lot of resources, so without a stable power supply and an acceptable tariff, mining quickly loses its meaning.
3. Cooling is equally important: overheating reduces performance and shortens the equipment's service life.
4. Constant access to the internet is essential — even short interruptions can lead to downtime and loss of income.
5. Take care of technical training. You need to be able to install and configure mining software, connect a crypto wallet, and monitor the equipment's stable operation.

Entry cost

The main costs are the purchase of equipment and electricity. The more powerful the equipment and the higher the consumption, the greater the initial investment. Additional costs include cooling, internet, and software configuration.

In 2026, more and more miners work through mining pools, combining their capacities with other network participants. Instead of rare but large rewards, they receive smaller but regular payments. The pool charges a commission for its services, which is important to consider when calculating profitability.

How to choose a coin for mining?

Start with a basic analysis: find out what algorithm the coin uses and whether it is suitable for your equipment.

Next, evaluate the project's economics. Pay attention to the network's complexity, the block reward size, and commissions. Keep in mind that projects with active development, a clear idea, and a stable community are more likely to retain their value in the long term. 

Mining Profitability in 2026

In this section, we will examine how profitable mining will remain in 2026 and what the final income actually depends on.

What affects profit?

Key factors:

• Cryptocurrency exchange rate;
• Network complexity;
• Electricity and equipment costs;
• Mining pool fees;
• Cooling costs;
• Possible changes to network rules (algorithm updates and halvings).

Examples of profitability

Knowing how cryptocurrency mining works, you can calculate its financial benefits. On average, in 2026, Bitcoin mining remains a long-term investment. The payback period for equipment is usually around 2.5-3 years. Mining certain altcoins can pay off faster — in about 1-1.5 years, but it carries higher risks due to market volatility.

Approximate calculations of the profitability of Bitcoin mining on an ASIC device:

• Equipment: Antminer S21 Pro
• Power (hash rate): 235 TH/s
• Power consumption: 3600 W
• Tariff: $0.05/kWh

In this case, Bitcoin mining will bring in approximately $6-$9 per day at a rate of $90,000 per coin.

You can calculate the profitability of mining without complex formulas using online calculators such as WhatToMine, 2CryptoCalc, NiceHash Profitability Calculator, and others.

Pros and Cons of Mining

Advantages of mining:

• Supports decentralization and stable blockchain operation.
• Ensures a high level of network security.
• Provides an opportunity to earn cryptocurrency without intermediaries.
• Allows you to work independently and control the mining process.
  
  

Disadvantages of mining:

• High energy consumption, expensive equipment, and maintenance costs;
• High competition, especially in popular networks;
• Possible protocol changes that can reduce profitability or make the equipment obsolete.

Mining Trends in 2026

Cryptocurrency mining continues to change under pressure from technology, the market, and regulation.

Network transition to PoS

In 2022, the Ethereum blockchain made the transition from Proof of Work to Proof of Stake. Cardano, Solana, Avalanche, Polkadot, Cosmos, Tezos, Algorand, and many other promising and new cryptocurrencies also use PoS. In such networks, new blocks are confirmed not by computation but by staking (storing and locking coins). This reduces energy consumption and makes network maintenance cheaper, but at the same time eliminates traditional mining. For participants, this means a reduction in the number of available coins and increased competition.

Risks and regulation

Governments are increasingly intervening in the mining sector. In 2026, various countries have restrictions on energy consumption, registration requirements, taxation, and reporting. In some regions, mining is becoming more transparent and legal, while in others, it is becoming less profitable due to strict rules and high tariffs. For example, cryptocurrency mining is completely banned in China. Sweden, Norway, and certain provinces of Canada have chosen to make mining more expensive by eliminating tax breaks and raising tariffs. Therefore, choosing a jurisdiction and understanding local rules remains an important factor for miners.
