CPU Mining: Is It Still Viable in Today’s Crypto World?


Cryptocurrency mining has undergone significant transformations since its inception, with early Bitcoin miners relying on central processing units (CPUs) for transaction validation and rewards. Nevertheless, the increasing complexity of cryptographic puzzles and the emergence of specialized hardware have led to a decline in CPU mining’s popularity. In this comprehensive exploration of mining evolution, CPU mining’s pros and cons, suitable cryptocurrencies, and setup guidance, we delve into the dynamic world of crypto mining.

The Evolution of Mining

Emergence of ASIC Mining

In the early days of Bitcoin, CPU mining was the norm. Miners could use their home computers to contribute to the network’s security and earn Bitcoin as a reward. However, as Bitcoin’s popularity grew, so did the difficulty of mining. This led to the development of Application-Specific Integrated Circuits (ASICs), specialized hardware designed solely for mining cryptocurrencies. ASICs offered significant advantages in terms of processing power and energy efficiency, quickly rendering CPU mining obsolete for Bitcoin.

GPU Mining Takes Over

As ASICs became dominant in the Bitcoin mining ecosystem, miners began to explore alternative cryptocurrencies, often referred to as “altcoins.” Many of these altcoins utilized algorithms that were still amenable to GPU (Graphics Processing Unit) mining. GPUs, which are more powerful than CPUs for parallel processing tasks, provided a substantial boost in mining capabilities.

CPU Mining’s Decline in Popularity

As GPUs gained popularity in the mining community, CPU mining gradually lost its competitive edge. The computational power and energy efficiency offered by GPUs made them the preferred choice for miners seeking profitability. CPU mining became less attractive, as it could not keep up with the hash rates achieved by GPUs and ASICs.

Current State of Cryptocurrency Mining

Today, cryptocurrency mining is a highly competitive and specialized industry. Bitcoin mining is almost exclusively dominated by ASIC miners, while GPUs are still the preferred choice for mining many altcoins. CPU mining, while largely overshadowed by these technologies, still holds some relevance in the crypto world.

The Advantages and Disadvantages of CPU Mining


  • Accessibility: CPU mining is accessible to virtually anyone with a computer. You don’t need specialized hardware, making it an inclusive option for newcomers.
  • Energy Efficiency: CPUs are generally more energy-efficient than GPUs and ASICs, making them a greener choice for those concerned about the environmental impact of mining.
  • Lower Hardware Costs: Since CPUs are readily available and often part of standard computing setups, the initial investment is relatively low.


  • Limited Profitability: The most significant drawback of CPU mining is its limited profitability. CPU miners struggle to compete with the processing power of GPUs and ASICs, leading to lower earnings.
  • Competition from ASIC and GPU Miners: In a competitive mining landscape, CPU miners face fierce competition from more powerful hardware. They are often outperformed in terms of hash rates and, consequently, revenue.
  • Network Security Concerns: The lower computational power of CPU miners can pose security risks to some cryptocurrencies, as they may become more susceptible to 51% attacks.

Coins Suitable for CPU Mining

Cryptocurrencies That Still Support CPU Mining

While CPU mining is not suitable for mining Bitcoin or other major cryptocurrencies, some smaller coins still support it. Notable examples include Monero (XMR), Litecoin (LTC), and Aeon (AEON).

Factors to Consider When Choosing a CPU-Mineable Coin

When considering CPU mining, it’s essential to choose the right coin. Factors to consider include the coin’s current market value, its mining algorithm, and the network’s overall hash rate. Monero, for instance, is often favored by CPU miners due to its CryptoNight algorithm and relatively lower competition.

Case Study: Monero (XMR)

Monero is one of the most popular cryptocurrencies suitable for CPU mining. Its focus on privacy and ASIC-resistant algorithm has attracted many CPU miners. To get started with Monero mining, you’ll need a CPU miner software, join a mining pool, and configure your mining settings.

How to Get Started with CPU Mining

Hardware Requirements

To start CPU mining, you need a computer with a reasonably powerful CPU. While any modern CPU can technically be used, higher-end CPUs will yield better results. Additionally, having a dedicated machine for mining is advisable to avoid affecting your regular computer usage.

Software and Mining Pools

Choose a mining software compatible with your CPU and the coin you wish to mine. Joining a mining pool is almost essential for CPU mining since the chances of mining a block on your own are exceedingly low. Mining pools combine computational power to increase the chances of earning rewards.

Setting Up a CPU Mining Rig

Install the chosen mining software and configure it to connect to your selected mining pool. You’ll also need to create a cryptocurrency wallet to receive your mining rewards.

Mining Strategies and Tips

To maximize your earnings with CPU mining, consider factors such as mining pool fees, payout thresholds, and the stability of your mining setup. Regularly check for software updates and stay informed about developments in the coin you’re mining.

The Future of CPU Mining

Potential Innovations in CPU Mining

While CPU mining may no longer be the dominant force it once was, there is room for innovation. Some developers are exploring ways to make CPU mining more competitive and profitable through algorithm changes or hybrid approaches.

The Role of CPU Mining in Decentralization

CPU mining can contribute to the decentralization of cryptocurrency networks. By allowing a wider range of participants to engage in mining, it reduces the risk of centralization and promotes network security.

Environmental Implications and Sustainability

The energy efficiency of CPU mining may make it a more sustainable option in the face of increasing concerns about the environmental impact of cryptocurrency mining. As cryptocurrencies face scrutiny for their carbon footprint, CPU mining could find renewed relevance.


In conclusion, CPU mining has evolved from its heyday in the early days of Bitcoin but is not entirely obsolete. While it may not be the most profitable option, it still offers accessibility and energy efficiency advantages. The choice to engage in CPU mining should be made carefully, considering factors like the specific coin, hardware, and current market conditions. As the cryptocurrency landscape continues to evolve, CPU mining may find new opportunities and contribute to the decentralization and sustainability of blockchain networks.
