CPU mining is the process of adding transaction records to the public ledger of cryptocurrencies by using the central processing unit (CPU) to perform the necessary calculations. It is well known that the CPU is part of the computer. Because mining tests the computing power and requires the computer hardware to run at full power and full load, it is bound to damage the CPU. CPU mining consumes power, memory, and CPU, and will also shorten the life of the computer. CPU mining is suitable for everyone who owns a computer, and there are some cryptocurrencies that can only be mined through the CPU. Many investors may not know much about the damage and impact of CPU mining on the CPU. Let the editor of the currency circle analyze it in depth for everyone.

 Damage and impact of CPU mining on the CPU

The CPU is part of the computer. Because mining tests the computing power and requires the computer hardware to run at full power and full load, it is bound to damage the CPU. You must know that mining requires the computer to run all the time to perform calculations and cannot be shut down. It is very demanding on the computer. The long-term high-frequency operation of the CPU and the long-term large-scale calculations of various components are all harmful, and the power supply requirements for the computer are also high.

Mining cannot be powered off, and it needs to be recalculated after the power is off. If the graphics card is used for a long time and performs a lot of calculations, the life of the graphics card will be greatly shortened. Therefore, it is not recommended to mine at home. The mining is not as expensive as the electricity bill. When mining, it consumes a lot of computer system resources, and the computer "eats" electricity. For every hour of mining, 1.5 kWh of electricity is required, and 24 hours a day, it consumes about 36 kWh of electricity.

 Introduction to the principle of CPU mining

Early versions of the Bitcoin client initially allowed CPU mining, but soon the hash rate of the network grew too much and CPU mining could not be profitable. The value of the bitcoins produced was lower than the power required to run the CPU. As a useless function, CPU mining was removed from Bitcoin Core, and GPU mining became the only way to mine Bitcoin for a while.

Due to the high hash rate of the network, most other cryptocurrencies, especially popular cryptocurrencies, cannot be mined profitably with CPUs. However, it is possible to find a new promising cryptocurrency that can be successfully mined with CPUs and make some profits in the long run.

There are some cryptocurrencies that are designed for profitable mining using CPUs. Most CPU mining coins are CryptoNight-based coins, such as Bytecoin, Quazarcoin, Monero, Electroneum, etc.

CryptoNight cryptocurrency was developed based on the ideas of the CryptoNote team, one of which is to allow everyone to mine despite their differences in computing equipment. Since CryptoNight-based coins use CryptoNote's egalitarian proof of work, they are taking advantage of built-in CPU instructions that are very difficult and too costly to implement in dedicated equipment (ASICs), but are very suitable for ordinary PCs.

The above content is the in-depth analysis of the damage and impact of CPU mining on the CPU by the editor of the currency circle. The profitability of CPU mining will be higher in three cases. The first is that the mined proof-of-work cryptocurrency is newly established and/or has a low hash rate, so it does not require high computing power from the miner's equipment. The other is that the mined cryptocurrency is designed for CPU mining and restricts more production types of mining hardware to participate in transaction verification. Finally, Miner can use many CPUs or CPU mining equipment and cheap or even free electricity sources. In fact, in most other cases, CPU mining is no longer profitable for the vast majority of cryptocurrencies.
