CPU mining. What to mine with cpu

Unlike the Bitcoin hashing algorithm, Ethash’s Ethereum algorithm was designed to be ASIC-resistant, which allowed CPU / GPU miners to participate in securing their network. As a result, at-home digging can still be profitable, provided they can use enough computing power with their GPUs to compete.

CPU mining in 2021 – List of CPU mineable coins & CPU only algorithms

A lot of people, when they talk about mining cryptocurrency, they discuss things like: profitability of ASIC mining, bitcoin mining machines, FPGA mining, building profitable Ethereum GPU mining platform, BTC mining with Nicehash, GPU mining altcoins, etc. GPUs and ASICs. But what about cpu mining? Is CPU mining still relevant in 2021 or is it a thing of the past?

The profitability of CPU mining in 2021, how is it? Are there coins that can really be mined from the CPU today and is it really worth building a CPU mining platform? Here this post is about mining CPUs.

CPU mining

Did you know that in the beginning, Bitcoin was only mined from the CPU? It was possible to mine bitcoins using an Intel Pentium processor and generate over hundreds of BTC in 2010. But that is no longer possible. Not only Bitcoin, but almost any altcoin.

Most common coins that were initially mined using CPUs are no longer CPU minable. There are two main reasons for this. 1. Increased network difficulty and 2. Increased number of complex ASIC (Application Specific Integrated Circuit) excavators. Both of these factors meant that CPU mining was largely concerned with the vast majority of coins

In any case, even today there are some cryptocurrencies that are still focused on CPU mining. One such popular coin is Monero (XMR, RandomX algorithm), the largest and easiest coin to mine by the CPU. Mining of Monero is profitable on AMD Ryzen processors and some Intel processors. But is it worth it and will you be able to get a return on your investment?

Sure, but that won’t work for all processors. Especially cheap, low-end processors are no longer profitable when it comes to mining. But at least a Ryzen CPU would pay off, but with the current difficulties with the network, it will still take over a year to obtain a return on investment.

Also, Monero is not the only coin that can be mined with the CPU. There are many other profitable coins that can be mined from CPU and CPU-only algorithms. If you are looking for a cpu algorithm or cpu only coins that you can mine with your cpu the following post is for you.

In this article, we have listed some cryptocurrencies that can be mined from the CPU even today. If you don’t have ASIC hardware or a fast GPU, no problem. You can still use your CPU power to mine these altcoins. They provide GPU / ASIC resistance and are intended for CPU mining only.

Now, before we just list CPU mining cryptocurrencies, let’s take a look at what CPU mining is.

What is CPU mining?

As you know, mining is an activity that allows a computer to solve complex mathematical puzzles, or algorithms. In this way, miners verify / validate a block of transactions in the blockchain, and for completing this process they mint new coins from the block as a reward. To learn more, learn about block rewards.

Typically, miners use ASIC machines to mine altcoins and allocate GPU power to their computers. But there are specific altcoins that can be mined with your CPU.

Processor mining is a process that uses CPU cores (Central Processing Unit) to verify blockchain transactions and create / mine new coins. Processor mining is the use of everyday computers or setting up processor mining platforms to use their power primarily as mining devices.

One CPU, One Vote:

Previously, cryptocurrency mining was originally only done using CPUs. However, a few years later, GPUs replaced CPU mining. Due to the limited power and speed of processing compared to graphics processors; The CPU mining process was slowly becoming ineffective.

The idea behind processor mining is “one processor, one vote” which is the consensus mechanism proposed by Satoshi Nakamoto in the Bitcoin White Paper. But this rule was broken with Bitcoin. For now, only some altcoins allow CPU mining.

CPU Altcoins

When it comes to CPU mining coins, the first crypto that comes to everyone’s mind at Monero. Monero is the only popular coin with the highest processor hashrate. It is the best CPU coin on the market today, and it is the most popular CPU coin on the market. To enable CPU mining, Monero uses the RandomX hashing algorithm, which is completely ASIC based and is very good at GPUs.

Finally, if your PC feels warm, make sure your mining device is clean and twilight-free. In addition, you can check the BIOS settings for CPU fan speed to aid cooling even further.


The CPUs are designed in such a way that they are very suitable for quickly switching between different tasks. Processors should be very well adapted to starting a new type of work, so that the user does not have to wait long between working with different programs. Processors are also very capable of executing “if this, do that, otherwise do something else” to quickly execute algorithms. However, the need to quickly switch between tasks meant that the processors were not well prepared for repetitive and lengthy mathematical calculations. Processors can perform math tasks because each processor has one or more “arithmetic logic units” (ALU). However, the GPU has much more ALUs than the CPUs,as a result, they can perform large amounts of mathematical work in more than the CPU.

CPU exploitation was initially allowed in earlier versions of the Bitcoin client, but fairly quickly the network hashrate grew too much for CPU mining to be profitable. The amount of bitcoin produced has become less valuable than the power needed to run the processor. As a useless feature, CPU mining has been removed from the Bitcoin core, GPU mining has become the only way to mine Bitcoin for a while. Most other cryptocurrencies, especially the popular ones, also cannot be profitably mined with the CPU due to the high hashrate of the network. However, it is possible to find a new, promising crypto that can be successfully mined with the processor and profitable in the long run.

There are several cryptocurrencies that are specially designed to profitably mine with your CPU. Most of the CPU mining coins are CryptoNight based coins such as Bytecoin, Quazarcoin, Monero, Electroneum and some others. CryptoNight cryptocurrencies are based on the ideas of the CryptoNote team, one of which is to make mining available to everyone, despite differences in computer hardware. As CryptoNight based coins use CryptoNote’s egalitarian proof of work, they use embedded processor instructions which are very difficult and too expensive to implement in special purpose devices (ASICs) but great for regular PCs.

Thanks to this approach, Bytecoin and its forks were only supported by the CPU and ASIC-resistant. However, some of the current ASICs work perfectly well with many CryptoNight coins, and mining them is not that profitable anymore. Even so, for example, the Monero team is actively fighting ASIC’s involvement in cryptocurrency mining, and even made a hard fork to keep the Monero CPU mining remaining the only way to create new XMR coins. There are also cryptocurrencies that are not based on CryptoNight and initially allowed for profitable CPU mining, some of which are Litecoin, Dash, Hatch, and ZCash.

Pros & Cons edit

  • CPU mining is available to anyone who owns a computer
  • Some cryptocurrencies can only be mined from the CPU
  • Processor mining is a good way to try cryptocurrency mining before making any purchases and investments
  • Using a CPU as an add-on for GPU mining can bring additional benefits to a miner
  • Processing mining is not profitable for mining most cryptocurrencies
  • CPU mining is not allowed when mining certain cryptocurrencies

To enable processor exploration, developers should design the Proof of Work algorithm with the processor in mind. Algo should primarily allow the CPU and keep ASIC miners at bay.

Hardware Specialization

Aside from bitcoin mining (which is dominated by ASICs), most of the blockchain hash power comes from GPUs. This is because CPU miners face significant hardware limitations, including:

  • relying on RAM instead of VRAM for hashrate
  • increased sensitivity to background processes and applications
  • fewer arithmetic logic units (ALUs) – do less math.

Speaking English: Unlike most consumer graphics cards, your CPU doesn’t have dedicated RAM. It rests entirely on the sticks on the motherboard for support. You can have a nice CPU with 12 cores, hyper-threading, and work – but you can’t beat the distance with 2GB of RAM.

Will CPU Mining Harm Your Computer?

While GPU mining is considered safe for long-term use, the jury is still not into CPU mining. Overheating should be your main concern with any important piece of computer hardware. Unsafe temperatures in key components (such as GPU and CPU) can cause immediate failure and possibly cause permanent damage to your computer.

For those of you who are sweating with nervous sweat, take comfort! The worst you’ll usually encounter is a blue screen or shutdown. The drivers are intelligent and will use whatever measures are necessary to protect your PC from a complete failure.

However, many CPUs don’t have unnecessary drivers, and they won’t get updated as often as your graphics card – so it’s up to you to keep your PC’s brains safe from confusion. Here are some professional tips for safely CPU mining:

Keep CPU Temperature Low

Most CPUs allow you to check the operating temperature directly in the BIOS, but third-party software like HWMonitor can be useful to control this. We generally recommend keeping the CPU temperature below 80 ° C. There is room to move on either side of that number (depending on your specific model, overclocking, and other factors), but it’s a good benchmark.

Limit Other Processes

The more you ask the CPU for it, the harder it will be. The harder it works, the hotter it will be. To avoid computer crashes – due to overheating or simple overload – minimize background and simultaneous processes while digging.

Trying to watch YouTube videos, play games, or even browse the Internet can unnecessarily burden your CPU and cause performance issues. Not to mention it will seriously lower your earnings rates. CPU mining is strictly AFK’s activity.

Clean Your Computer Often

Keep as little dust and debris as possible inside the computer, including fans and boards. Stock up on a can of compressed air and go to town inside your computer – all of this requires some proper spring cleaning from time to time.

Pay special attention to the fans on the GPU and CPU, as these directly cool the hottest components and clog up quickly. Also, make sure your computer can breathe.

Install Cooling Systems or Components

Extra cooling is never bad as long as you pay attention to maintaining proper airflow. There are a number of components you can add to keep your PC nice and cool, such as:

Each of these additives can help keep important components within safe temperature ranges.

However, many CPUs don’t have unnecessary drivers, and they won’t get updated as often as your graphics card – so it’s up to you to keep your PC’s brains safe from confusion. Here are some professional tips for safely CPU mining:

Do You Need a Good CPU For Mining?

Absolutely. If you are planning on CPU mining, you need the best CPU you can buy. We’ll write down what to look for here.

In addition to choosing one of the less difficult cryptocurrencies to mine for your CPU, there are several factors to consider when deciding on the CPU itself:


The more cores in the CPU, the better the mining experience will be. The extra cores mean your CPU can multitask much more efficiently, and an 8-core CPU is a good place to start.


Depending on whether you have an AMD or Intel processor, you can also make use of threads. The thread causes the CPU to divide the base number of cores into even more, making it run faster and smoother than otherwise.

Generally speaking, a processor can thread up to twice its base amount. For example, a 4-core CPU can produce up to 8 threads on average. The more threads the better.


Mining requires a fairly high hashrate to do it properly. To meet such requirements, you will need a processor with a competing frequency, often represented in GHz. The faster your frequency, the higher your hashrate will be, allowing you to defeat other miners.

Remember that a CPU that underperforms in any of these categories could lose money. These devices may be able to mine, but the electricity costs will outweigh any gains. Invest in a solid processor.

Also, don’t use your laptop for CPU mining. Even if your laptop has the best processor, these devices are not designed to handle the heat and electricity consumption that this process takes. Make sure you are using a desktop computer with a decent power supply as well as the factors mentioned above.

How to Start CPU Mining

Now that you know what makes your CPU good for mining, it’s time to start the process itself. Here are some ways to kick your CPU.

Solo Mining

You can dig yourself, but it is not recommended. As mentioned, you have to be the first to solve the block algorithm to get your reward. Solo mining pits you against a variety of powerful machines – many of which will beat your CPU.

Don’t try this unless you absolutely know what you are doing.

Mining Pool

A mining pool is one of the more popular ways to participate in both CPU and GPU mining. You basically enter a pool with hundreds of other miners working to solve one block. With all that power harnessed together, the chances of you’ll do it first are much higher. From there, the prize is shared among all participants based on their contribution.

Examples of mining pools for CPU mining include Nanopool for Various Assets or MineXMR for Monero. Remember that the pools also charge a percentage of any profits.

As you know, mining is an activity that allows a computer to solve complex mathematical puzzles, or algorithms. In this way, miners verify / validate a block of transactions in the blockchain, and for completing this process they mint new coins from the block as a reward. To learn more, learn about block rewards.

Horizen (ZEN)

Horizen is another privacy-oriented digital currency on the list of the best cryptocurrencies for home mining. The cryptocurrency was launched in 2017 after a hard fork from the parent blockchain Zclassic. The fork was inspired by the differences with the launch of Zclassic, which community members felt was skewed in favor of the developers. After its premiere, ZenCash changed its name to Horizen.

ZEN uses the Equihash algorithm, which is ASIC-resistant and therefore well-suited for home mining. Additionally, Horizen is considered to be the best Equihash coin in terms of prizes won.

Horizen mining is a fairly simple process. Download the official client to your computer, install the program, and configure the settings for your GPUs. After setup is complete, join the mining pool to optimize your potential profits.


AEON (Anonymous Electronic On-line Coin) started out as a hard fork of Monero CryptoNote’s earliest consensus algorithm. Today, digital currency has become a popular cryptocurrency in its own right thanks to its innovative features.

AEON is great for in-home mining due to its mobile friendly status. The blockchain on which the digital currency is based is designed to trim the data downloaded to the device based on its capacity. As a result, it is easy to run blockchain and its consensus algorithm on devices with limited memory, such as processors, without much effort.

AEON is a privacy coin and uses its own modified version of the CryptoNote protocol, called Cryptonite-light. Cryptonite-light quickly verifies the underlying blockchain. The lock time in the privacy coin is four minutes.

To start mining, simply download the software, set up GPUs, and follow the instructions.

Typically, miners use ASIC machines to mine altcoins and allocate GPU power to their computers. But there are specific altcoins that can be mined with your CPU.

Mining with a CPU in 2018

You might be surprised to learn that not only cpu mining is still a thing, but that there are actually coins that are intended to be mined only with cpu (meaning they cannot be mined with the GPU or ASIC Period: Some of these coins were specifically designed to stop what happened to Bitcoin and to prevent miners with a lot of money from centralizing their networks into just a few small pools.

The coins on this list can only be mined using processors.

  • MonteVerde– Only the processor (website currently unavailable, my coin is dead)
  • Riecoin – CPU only, mined by a private miner.

List of CPU and GPU Coins

These coins can be mined using the CPU, but using a GPU will give you an advantage.

  • Bytecoin – GPU to mine on both ATI and AMD or CPU. Mined using ATI Miner Claymore (closed source, 5% mandatory for developer) or Tsiv’s ATI Miner which is open-source.

We will update this list as more coins become available. Processing mining is still possible.

The basics of CPU mining are similar to GPU mining, but the devil is in the details. There are a few key differences worth mentioning before you get started.

Is CPU Mining Profitable?

As you’ve heard about cpu mining, you surely have some question in mind. Plus, it’s unfair, if not to mention the CPU mining profitability isn’t that significant for short-term gains.

The most important point we want you to realize is that most of the coins worth mentioning in CPU mining are still in their infancy and the stock quotes at this stage are usually little or almost none. So why still bother with a processor extracting these coins?

First, it may be the only way to get some of these coins for safekeeping in advance, as we try to mine them when the profits are much higher. So the idea is to build up your chips early and hold them on until the coins you mint are worth more money.

However, we want you to understand that cryptocurrencies are considered speculative and volatile, which makes it difficult to predict their future prices. Finally, there are suggestions from what we learned from our time in the crypto community.


CPU mining is an easy way to earn a few cents a day. But mostly if you have the right equipment and can get the right coin. Also, if you come across such coins and your CPU is efficient at mining, start your CPU. Otherwise, it is better to keep them idle. All that money, energy, and time spent on random shitcoin are not worth it anymore.
