How Cryptocurrency Mining Works?

21 March 2023

In an increasingly digital world, investing in cryptocurrency has emerged as a potentially lucrative option for people seeking a passive income stream. Moreover, the market volatility often presents opportunities for investors to benefit from simply HODLING their assets. 

However, as the technology behind cryptocurrencies has continued to evolve, there are now more opportunities for users to earn with cryptos. One such option is crypto mining. With the proper technical facilities and knowledge, anyone can participate in this process to generate rewards and contribute to the security and integrity of blockchain networks. 

Here, we’ll break down the entire process of cryptocurrency mining, from the fundamentals up to the most complex techniques.

Key Takeaways

  • Crypto mining is the process of creating new blocks to a blockchain and validating cryptocurrency transactions on a network. 
  • For those with the hardware and technical know-how, mining cryptocurrency can be a great passive income. 
  • Mining has been criticized for its possible adverse environmental implications due to its massive energy use and high electricity costs. 
  • Staking, which involves holding a certain amount of cryptocurrency to participate in the network’s consensus process, is frequently seen as a more environmentally friendly alternative to mining.

What Does Mining Cryptocurrency Mean?

To put it briefly, the cryptocurrency mining process is to verify new transactions and add them to a blockchain, a digital ledger of all transactions made in a cryptocurrency network. This process requires a substantial amount of computing power, and miners who provide this power are compensated in cryptocurrency. Only blockchains that use a Proof of Work (PoW) consensus algorithm are qualified for mining.

How Cryptocurrency Mining Works?

All transactions made on a cryptocurrency network are broadcast to all nodes simultaneously. As soon as these nodes verify a transaction, it is added to a queue of pending transactions. Miners then compile a group of these unconfirmed transactions into a new block, which is subject to a consensus before being added to the blockchain.

A new block can only be added to the blockchain once a miner solves a complex math puzzle.

Despite our use of the word “Complex,” which the first miner can perceive as threatening, no complex calculations or mathematical reasoning are required. When competing for a cryptocurrency, miners race to be the first to generate a 64-digit hexadecimal number (a “hash”) smaller than or equal to the target hash. All they do is speculate. The miner who solves the puzzle and adds the block to the blockchain first receives cryptocurrency as a reward.

How Cryptocurrency Mining Works?

Cryptocurrency mining has multiple purposes, including ensuring the integrity of the network by confirming and recording transactions in a distributed blockchain ledger. The blockchain is a distributed ledger, so it does not require a central authority to regulate transactions. By having miners solve complicated riddles to add blocks to the blockchain, the network becomes more resistant to hostile actors’ attempts to manipulate the ledger.

How Does Bitcoin Mining Work?

Cryptocurrency mining is typically illustrated with Bitcoin (BTC), the most widely used cryptocurrency. The Bitcoin mining process involves adding blocks to the Bitcoin blockchain every ten minutes. The current Bitcoin mining reward per block is 6.25 BTC, which is halved once every four years or every 210,000 blocks. This “halving” means reducing the Bitcoin supply and aims to control the total number of Bitcoin in circulation and thus prevent inflation.

This most recent halving of Bitcoin’s block rewards happened in May 2020, when they were cut in half from 12.5 BTC to 6.25 BTC. Bitcoin miners may expect to earn about $137,500 in March 2023, when the cryptocurrency is valued at roughly $22,000.

How Cryptocurrency Mining Works?

The competition for Bitcoin mining rewards is intense, as it requires a significant amount of computing power to earn rewards. This power is measured regarding hash rate or the number of calculations a miner can execute per second. The total BTC hash rate has surpassed 350 EH/s as of March 2023, with the largest Bitcoin mining pools controlling the vast majority of this processing power.

Types of Cryptocurrency Mining

Various cryptocurrency mining strategies exist, each with its advantages and disadvantages. Let’s discuss each alternative to determine which is the most suitable for you.

  1. ASIC Mining

ASIC mining is a subset of cryptocurrency mining that employs application-specific integrated circuit ASIC. These Integrated Circuit ASIC miner rigs are purpose-built for mining, making them much more potent and efficient than regular computers. That makes cryptocurrency mining with them significantly more efficient than with other methods.

However, it’s essential to remember that introducing new ASIC models can quickly render previously profitable designs unfeasible. 

ASIC Rig Profitability Comparison

How Cryptocurrency Mining Works?
  1. GPU Mining

A Graphics Processing Units (GPU) mining rig uses traditional computer hardware to mine cryptocurrencies. In this method, the computer’s graphics card performs complex calculations needed to mine cryptocurrencies.

GPU mining is more accessible than ASIC mining, as it can be done with standard computer hardware. It is also more versatile, as it can be used to mine a variety of different cryptocurrencies. 

  1. CPU Mining

CPU mining directly utilizes a computer’s central processing unit (CPU) to generate new coins. While this approach is less efficient than a graphics processing unit or application-specific integrated circuit, it is cheaper and easier to implement.

Newer, less well-known cryptocurrencies with less mining competition are often mined using CPU. Keep in mind, though, that in contrast to GPU and ASIC mining, CPU mining typically yields lower rewards.

How Cryptocurrency Mining Works?
  1. Solo Mining

Solo mining refers to mining cryptocurrencies independently, without collaborating with others in a mining pool. The miner is responsible for successfully providing all the processing power required to mine the cryptocurrency in this method.

Solo mining can be more profitable because the miner keeps all the rewards they earn. However, the miner’s computing power is limited to their resources, making this method less efficient.

  1. Mining Pools

To mine cryptocurrencies more rapidly and efficiently, miners often form “mining pools,” where they pool their resources and share the proceeds equally. 

Mining pools are a convenient way for small-scale miners to earn rewards and engage in mining. And because the pooled computer power makes the mining rewards more stable than they would be with a single machine, they are more efficient than solo mining.

  1. Cloud Mining

Miners using a cloud mining service can generate crypto earnings without being responsible for or needing any mining hardware. Users gain access to the mining hardware of a cloud mining company by purchasing mining contracts from it. 

Yet, cloud mining is less profitable than traditional mining due to the cloud mining service’s portion of your earnings. The return on investment is also uncertain because several services have been exposed as frauds.

How To Mine Cryptocurrency: A Step-By-Step Guide

Crypto and mainly Bitcoin mining can be a profitable venture if done correctly. Here’s a step-by-step guide to help you get started to get a steady stream of digital currency.

How Cryptocurrency Mining Works?
  1. Choose Crypto To Mine

Mining difficulty varies across cryptocurrencies as the network’s effort to mine a block differs in each case. The greater the number of miners in a network, the more difficult it becomes to produce a valid hash. When miners leave the network, however, the hashing difficulty drops, making mining a new block easier.

It is more difficult for individual miners to earn a profit when they are mining the most popular cryptocurrencies, as their requirements are challenging to meet. 

  1. Get The Right Mining Tools

Mining cryptocurrencies is very much competitive. With more robust mining hardware, miners compete to increase their odds of successfully mining the next block in the mining competition. Because of their specialized construction, ASIC miners are typically the most efficient choice when mining cryptocurrencies. Even so, GPUs are still helpful in some networks; the efficiency of this method varies depending on the difficulty and algorithm used by the particular cryptocurrency in question.

  1. Set Up A Crypto Wallet

A crypto wallet is required to hold the private keys to the cryptocurrency you mine. The mining program will send the funds to the wallet address you provide for your mining cryptocurrency.

  1. Install Mining Software

You must download a specialized mining operating system to mine cryptocurrencies. For example, you can download the mining software directly from the official cryptocurrency website you want to mine. In this way, you won’t have to worry about downloading malicious apps in the name of a cryptocurrency, and you can rest assured that you’ll be using the correct software.

  1. Start Mining!

After completing all steps, you are prepared to begin mining. The mining software will use your computer’s processing power to solve complex mathematical equations and verify blockchain transactions. Each time the software finishes a task, you receive a portion of the block reward, typically paid out in the cryptocurrency you are mining.

Cryptocurrency Mining Costs To Consider

Many different types of expenses arise from mining cryptocurrencies, which are worth considering before starting mining.

  • Energy Expenses

Since mining requires substantial electricity to power the computing equipment, energy consumption is one of the largest expenses. In this way, the price of electricity in a given region can have a major effect on the industry’s profitability.

  • Hardware Costs

Hardware costs can significantly impact mining profitability, such as the purchase price of specialized application-specific integrated circuits (ASICs).

  • Maintenance Fees

Prices for upkeep and repairs: Keeping mining machinery in top shape comes at a cost, as it requires regular servicing and fixes to keep running efficiently.

  • Cooling Fees

To maintain the health of the machines, the heat generated by the mining equipment must be dispersed. Therefore, the costs associated with cooling could be relatively high, particularly in regions with higher average temperatures or large-scale mining operations.

Drawbacks Of Cryptocurrency Mining

In recent years, mining has become a lucrative industry for many businesses and individuals. Despite the industry’s success, several drawbacks have emerged as it expands.

  1. Environmental Impact

Crypto mining damage to the environment is among the industry’s biggest drawbacks. Energy for mining comes primarily from fossil fuels like coal and natural gas. Depending on the source, the worldwide electricity consumption for crypto-assets in 2023 is estimated to be anywhere from 120 to 240 billion kilowatt-hours per year. This is more than the annual electricity consumption of many countries, including Argentina and Australia.

This excessive use of energy resources releases more carbon into the atmosphere. Also, mining produces excellent heat, necessitating elaborate cooling systems that give up even more power.

  1. Expensive Equipment

The high cost of equipment is another problem with cryptocurrency mining. The needed equipment gets harder and more expensive. Keeping up with the competition requires frequent upgrades to mining equipment, which can be costly.

A Bitcoin mining rig, for instance, can cost anywhere from several thousand to tens of thousands of dollars, depending on the hardware it employs. In addition, little things like electricity bills and repairs always add up.

  1. Legal Concerns

Cryptocurrency mining’s legality has been hotly debated recently, with many nations passing regulations to curb the practice. For environmental reasons, some nations have outright forbidden Bitcoin mining, while others have instituted stringent guidelines for the industry.

How Cryptocurrency Mining Works?

For instance, the Chinese government has recently cracked down on the mining industry due to worries about the industry’s excessive energy use. To prevent a shortage of electricity for residential use during the summer, the Iranian government has also banned cryptocurrency mining until the end of the season.

In addition, countries like Venezuela have seen increased regulatory scrutiny because mining has been used as a tool for illegal activities like money laundering and financing of terrorist activities.

  1. Entry Limitations 

The difficulty of PoW mining rises over time, making participation by the general public more challenging. In a decentralized PoW network, users share the workload and the rewards. However, as mining becomes more complex and challenging, only the largest companies can afford to invest in warehouses full of mining machines, giving them a monopoly on the industry.

Can You Still Profit From Cryptocurrency Mining In 2023?

Cryptocurrency mining is still profitable in 2023, but not as lucrative as it once was, given that cryptocurrency prices have declined from their peaks and mining operations have become more costly to operate and maintain.

According to these forecasts, 2023 may be your last chance to enter the Bitcoin mining industry. Roughly speaking, there are still about 2 million new Bitcoins to be mined. Each new block is mined every 10 minutes on average, and as said, the current block reward is 6.25 (it will remain so until the next Bitcoin halving).

Interestingly, increased competition for blocks results in a higher hash rate, but the number of newly minted coins remains unchanged. Consequently, while we are not implying that would-be miners won’t turn a profit, it’s worth mentioning that as the industry gets more competitive, there are more factors to think about than it was in the past.

Will PoS Replace PoW?

Greener alternatives are being implemented across all technology sectors as the world shifts its focus. So, it’s not surprising that cryptocurrencies are included. Proof of Stake networks has emerged as more accessible and eco-friendly alternatives to Proof of Work regarding network maintenance and user reward. Let’s discuss staking and how you can benefit from it. 

Staking has shaped into an alternative to mining that involves locking up a certain amount of cryptocurrency in a wallet rather than using computational power to solve complex mathematical problems to validate transactions on a blockchain. 

It doesn’t require much processing power, making this method much better for the environment and conserving energy than mining. 

Investors who contribute to the safety and reliability of the network can benefit from staking in the form of newly issued tokens or transaction fees. 

As criticism of cryptocurrency mining intensifies, the crypto market has embraced staking as an alternative.

The trend towards switching to the PoS ecosystem was easily reflected in Ethereum Merge when the network switched from PoW to PoS. The primary goal of this merge was to reduce the network’s environmental impact while making it easier for regular people to take part in the network rather than just large mining corporations.

Consequently, while mining is still popular among the miner community, we may soon see a significant shift toward staking unless energy-sustainable mining options are implemented.


  • Is Bitcoin mining legal?

Mining is legal in most countries. However, a few nations have criminalized mining Bitcoin: Algeria, Bangladesh, China, Egypt, Iraq, Morocco, Nepal, Qatar, Russia, and Tunisia explicitly.

  • Can I mine crypto at home?

To start mining cryptocurrency at home, acquire a cryptocurrency wallet, mining rigs, and mining software, and join a mining pool.

  • Which cryptocurrencies can I mine?

You can mine cryptocurrencies that run on the Proof Of Work network. For instance, Litecoin, Ethereum Classic, Dogecoin, Vertcoin, Grin, Monero, ZCash, Ravencoin, and Haven Protocol can all be mined.

  • How long can it take to mine one Bitcoin?

A solo miner may need 10 minutes to produce one Bitcoin at the current difficulty level. But, for most miners, obtaining a Bitcoin reward takes 30 days on average.

  • Is Bitcoin mining profitable?

Monthly profits from home-based Bitcoin mining range from $30 to $450 per mining rig.

Final Takeaway

With the ever-increasing value of cryptocurrency, mining has always been a highly sought-after and rewarding endeavor. Although mining demands a major financial commitment in hardware and energy usage, the potential returns might be substantial for those prepared to devote themselves to the process. 

Yet, there are obstacles – mining difficulty increases, competition rises, regulations get stricter, and staking networks grow. How mining alters and adapts to the changing cryptocurrency market remains an open question.
