Cryptocurrency Mining: Processes, Costs, and Sustainability Considerations

If you know digital currencies, cryptocurrency will not be a new term. But are you aware of how the cryptos come in the first go? Like the central body or the government prints fiat currency, mining is done to produce cryptocurrencies. 

Cryptocurrencies such as Ethereum and Bitcoin are transacted on the blockchain network. Although there are different ways of making cryptos, mining is among the most popular. Let’s understand the mining process through this article.

What is Crypto Mining?

Crypto mining is a complex technological process to validate crypto transactions over the blockchain network. It is the process through which a block is validated on the chain network to get paid in crypto. This process allows cryptocurrencies like Bitcoin to function without a centralized authority. People who are involved in mining are referred to as crypto miners.  Why is it called mining? Like natural resources, there is a finite amount of cryptos available. The maximum amount that can be mined or created is 21 million. Moreover, people need to invest a lot of energy for mining, which can be electrical energy.

Cryptocurrency Mining - The Process

Cryptocurrency mining involves verifying transactions and adding them to the blockchain through a computationally intensive process. Below are the detailed steps involved in cryptocurrency mining:

Use of Powerful Hardware Resources

Mining requires the miners to solve complex puzzles efficiently; they need powerful tools and computer resources. They may require GPUs (graphics processing units) with advanced graphic cards, ASICs (application-specific integrated circuits), or FPGAs (field programmable gate arrays) for mining. The most advanced today is ASIC, among the most expensive.

Use of Mining Software and E-wallets

Besides the hardware, miners also need software for minting cryptos. They can use software like XMR Miner, CGMiner, and Multiminer. Most software is free and can be downloaded on Mac and Windows. 

Once the software is downloaded, miners will require an e-wallet to store their crypt rewards. A crypto wallet is where miners can store, transfer and accept cryptocurrencies.

Solo Mining or Mining Pool

Miners can perform mining in two ways – solo or within a mining pool. Mining pools are available since mining is complicated and challenging. In a pool, different miners come together to solve complex puzzles and are paid for their work.

Solo mining may be challenging for small miners since it may be challenging for them to clear all the complications. But with combined computation power, small miners can also get some share in the mining pool.

Get Ready for Mining

Once everything is set up, the miners must solve complex and challenging mathematical problems or puzzles. These are done to validate the transactions on the blockchain network. For each transaction, a cryptographic hash is developed by the mining software. It bundles all the trades required for generating a block using SHA-256 encryption. This process is referred to as a Merkle or hash tree. 

Once this tree is generated, the transaction data is reviewed and organized into several blocks with their address by a proof-of-work (PoW) algorithm. A validated block must contain PoW, ensuring the blocks are mined at a specific speed while maintaining their integrity.

Every block has a unique hash, always a 64 digits number. For every 2,016 blocks, the network chooses the specific target hash. The goal is to keep the mining difficulty at a level where a block gets mined on average every ten minutes. 

The mining difficulty measures how difficult it is to find a hash below the target value. And the hash rate defines the rate at which a miner’s computer can make several guesses per second.

Cost Involved in Cryptocurrency Mining

Some of the costs involved in the cryptocurrency mining process are as below. These costs are irrespective of whether it is a home setup or a professional warehouse setup.
  1. An ASIC miner will cost between $3000 to $5000; you can even buy second-hand or older models. 
  2. Next will be the electricity cost to cool and run these ASICs.
  3. You will have to calculate further the maintenance and housing costs of the entire operation. It will also include the internet cost needed to run the setup.
As of June 2023, below is the estimated cost for mining:
  • Cost of electricity – $0.05/kWh
  • Other expenses (mining pool fee, internet cost, and staffing) – 20% of the electricity cost
The formula for calculating the cost required for mining one bitcoin will be as below: Capital Expenditure + electricity + other operational expenses per Bitcoin

Is it Environmentally Friendly to Mine Cryptocurrency?

Cryptocurrencies require a lot of electrical energy, which comes with substantial electronic waste. Digiconomist reported 130.3 Terawatt-hours of energy used through 9th July 2022.  It calculates to around 1,455.8 kilowatt-hours of electrical energy per transaction. It is also the same amount of electrical power an American household uses for almost 50 days. According to Digiconomist, the annual carbon dioxide emissions from crypto mining are roughly 73 million tonnes, equivalent to Turkmenistan’s energy output. At the same time, crypto mining also produces a lot of electronic waste. Digiconomist stated an annual electronic waste of 38 thousand tons worldwide. So, is crypto mining eco-friendly? It is a commonly asked question. Some crypto mining requires a lot of electrical energy consumption, making them less environmentally friendly. Moreover, it is difficult to say whether it can be made eco-friendly. Mining crypto will need powerful resources, so it is doubtful that it can ever reduce carbon footprints.


Crypto mining is a huge and vast process that involves multiple steps. Each step involves a substantial cost and affects the environment in one way or another. While cryptocurrency mining offers lucrative opportunities, it also entails costs and sustainability considerations. 

Energy consumption is a significant concern, particularly in PoW-based cryptocurrencies, as the computational requirements demand actual electricity usage.

Additionally, there are expenses associated with mining hardware, operational costs, and regulatory considerations that can impact profitability. In response to environmental concerns, the industry is exploring sustainable alternatives, such as PoS and renewable energy solutions, to mitigate the carbon footprint of mining operations.
