The rise of hardware costs and the expansion of mining pools have led to increasing centralization in the mining industry. However, many people are surprised to learn that it's still possible to mine cryptocurrencies using a standard PC or GPU. While your chances of successfully mining a major network like Bitcoin are extremely low, exploring alternative cryptocurrencies can offer more accessible opportunities.
Fortunately, numerous projects utilize advanced protocols specifically designed to limit the advantage of high-performance ASIC (Application-Specific Integrated Circuit) mining equipment. These specialized devices are built to solve particular consensus algorithms and typically outperform standard PC and GPU mining setups by thousands of times.
The Case for Fair Cryptocurrency Mining
When Bitcoin first emerged, it was designed to be open, transparent, and accessible to everyone. This vision was one of the primary reasons for selecting a 1MB block size, a parameter that remains in place today. The original idea was that anyone should be able to mine Bitcoin and help secure the network.
Unfortunately, this ideal no longer matches reality. While technically you can still use a PC to attempt Bitcoin's Proof-of-Work algorithm, the intensely competitive nature of Bitcoin mining means you'd likely just waste electricity without meaningful rewards.
How ASIC Miners Changed the Game
Initially, ASIC miners introduced new profitability levels for early adopters. However, as Bitcoin mining grew increasingly popular, these specialized devices created a highly competitive environment that pushed out casual miners. Consequently, the probability of earning rewards on the Bitcoin network with a standard PC is now virtually zero.
The projects listed below have implemented various strategies to maintain mining accessibility. They employ modified, randomized, and combined consensus algorithms specifically engineered to resist ASIC mining equipment. These protocols recognize the problems caused by mining centralization and take proactive measures to prevent similar issues in their platform development.
Here are 10 cryptocurrencies you can still mine using a PC or GPU, presented in no particular order.
1. Bitcoin Gold (BTG)
Bitcoin Gold represents a unique project created specifically to combat mining centralization. Launched in Q1 2017 as a hard fork of Bitcoin, the project was developed by Bruce Fenton, Tron Black, and Joel Weight with the goal of democratizing cryptocurrency mining.
This first-generation cryptocurrency shares many technical aspects with Bitcoin, including a capped supply of 21 million tokens and a 10-minute block time. These similarities led some early critics to dismiss the project as a cash grab. However, examining its consensus mechanism reveals significant differences between the two networks.
Bitcoin Gold utilizes the Equihash consensus mechanism, first proposed as an ASIC-resistant option at the 2016 Network and Distributed System Security Symposium (NDSS). This consensus algorithm frequently switches its approach, significantly reducing the efficiency of ASIC systems.
Notably, Bitcoin Gold experienced a rocky start when the network suffered a 51% attack in May 2018, resulting in significant losses. This attack was possible due to the network's relatively low hash rate at launch. Since then, developers have substantially upgraded the consensus mechanism, with no major incidents reported since the improvements.
2. Zcash (ZEC)
Zcash entered the market in 2016, founded by Zooko Wilcox-O'Hearn. The project aims to provide users with enhanced security and anonymity through its innovative privacy features. The network employs a method called zero-knowledge proofs, which allow transactions to be verified without revealing sensitive data about the participating parties.
Among Zcash's notable features is the ability to choose between private and public transactions. This flexibility allows Zcash to serve diverse use cases, providing complete transparency when required while maintaining privacy when desired. Zcash users benefit from strong privacy protections, robust security, and a limited supply of 21 million tokens.
Zcash uses the Equihash consensus algorithm as part of its decentralized mining strategy. Equihash has proven effective at reducing ASIC miner dominance without compromising average returns for GPU and CPU miners. Consequently, it remains one of the most popular ASIC-resistant methods adopted by blockchain projects today.
Zcash incorporates community governance mechanisms to maintain cohesion and alignment with future developments. The project boasts a strong community following and ongoing development that keeps it relevant. For these reasons, ZCash remains a viable option for PC mining enthusiasts.

3. Vertcoin (VTC)
Vertcoin has existed since the early days of the cryptocurrency market, launching in January 2014 as a Bitcoin hard fork. The project's main attractions include privacy features, mining decentralization, and scalability improvements.
Vertcoin integrates a modified version of the Lyra2REv3 algorithm specifically designed to resist ASIC mining. This mechanism incorporates multiple protective measures to prevent and reduce ASIC miner effectiveness. One key feature is its memory-hard function, which requires substantial memory to perform mining calculations.
Additionally, the process uses a series of hash functions and memory accesses that further diminish the advantage of high-performance specialized equipment. ASIC miners struggle to handle the variety of algorithms employed by this system.
4. Bytecoin (BCN)
Bytecoin (BCN), launched in July 2012 as another Bitcoin hard fork, aimed to level the mining playing field by integrating proprietary protocols. The network emphasizes privacy options and scalability as its main advantages. Specifically, Bytecoin utilizes the CryptoNote Proof-of-Work protocol to obscure sender, receiver, transaction values, and other metadata.
CryptoNote reduces ASIC miner effectiveness through memory cache and access functions. This memory access operates across extensive data models that are difficult for specialized chips to handle efficiently. Additionally, the consensus uses an adaptive algorithm that adjusts over time to maintain ASIC resistance.
Bytecoin was considered advanced for its time because it incorporated ring signatures and stealth addresses. These features remain popular today, though they're not considered as private as when they were first introduced a decade ago.
5. Ethereum Classic (ETC)
Ethereum Classic represents the original Ethereum blockchain that continued after the controversial decision to roll back the network and implement a hard fork following the theft of $50 million in Ether. This incident remains one of the most notable hacks in cryptocurrency history, with the hacker even debating with developers on social media about the ethics of the reversal.
The hacker argued that if The DAO was designed for automated decision-making, then its outcomes should be honored. Despite these arguments, Ethereum proceeded with the hard fork, abandoning what became Ethereum Classic. However, not all Ethereum users followed the new chain, and the project continues to exist today.
This controversial decision generated significant backlash and potentially limited Ethereum's adoption for applications requiring legal finality. Imagine a scenario where tokenized stock or bond settlements could be reversed because the supporting blockchain allows transaction rollbacks.
While Ethereum has upgraded to ETH 2.0 Proof-of-Stake, Ethereum Classic remains a Proof-of-Work network. This means you can still use PCs and GPUs to mine Ethereum Classic. This capability is possible because Ethereum Classic utilizes the Ethash consensus mechanism, which incorporates memory-hard functions that resist ASIC optimization.
6. Monero (XMR)
Monero has been and remains the dominant privacy coin in the cryptocurrency market. This controversial coin launched in April 2014 with advanced features designed to keep transactions anonymous. The network supports ring signatures, stealth addresses, and confidential transactions among its privacy protections.
One of Monero's defining characteristics is its commitment to fungibility. Developers want to ensure every XMR is indistinguishable from others to guarantee all tokens maintain equal value. Notably, fungibility represents a core component of privacy, as it ensures no tokens can be blacklisted or censored.
Monero uses the CryptoNight consensus algorithm to maintain decentralization within its mining community. This approach continues to allow users to mine with PCs or GPUs. The system also incorporates common ASIC-resistant features like memory-hard functions and frequent algorithm updates. Today, Monero remains a popular project despite controversial claims from forensic companies alleging they can破解 its privacy features.
7. AEON
AEON is another privacy coin that aims to promote decentralization in cryptocurrency mining. The project entered the market in 2014, initially launched as a hard fork of the Monero blockchain. Consequently, it shares many privacy features with Monero, including ring signatures, stealth addresses, and confidential transactions.
Notably, AEON is classified as a lightweight blockchain that you can mine using a PC or GPU. This designation means the network is optimized for low-power devices like smartphones. These blockchains feature lower memory requirements and offer faster data synchronization capabilities.
AEON utilizes the CryptoNight-Lite consensus system. This version of the CryptoNight consensus is specifically optimized for CPU mining. It includes memory and algorithm adjustments similar to other projects on this list.
8. Ravencoin (RVN)
Ravencoin was developed in 2018 by Bruce Fenton, Tron Black, and Joel Weight. This blockchain aims to simplify the tokenization of real-world assets. The project makes it easy for anyone to convert physical items into decentralized digital assets. Consequently, Ravencoin finds applications in finance, gaming, supply chain management, art, security, and intellectual property.
Ravencoin introduced the X16RV2 consensus mechanism, specifically designed to be ASIC-resistant. This protocol integrates different algorithms that change frequently. Notably, these algorithms are selected from a large pool, making it difficult for ASIC manufacturers to narrow their focus effectively.
Ravencoin maintains an active community and has undergone multiple upgrades and improvements that enhance security, scalability, and functionality. Additionally, the team behind the project has established strategic partnerships to expand the platform's ecosystem.
9. Grin
Grin is another privacy coin that can be mined with a PC. The project employs interesting methods to help protect users from centralization. Active since January 2019 and completely open-source, this blockchain focuses on scalability and is based on the Mimblewimble protocol.
Interestingly, Grin's token issuance schedule is set at one token per second. Additionally, it's a lightweight blockchain, making it well-suited for mobile use. The project also incorporates a community governance model that gives users a voice in future developments.
Grin uses the Cuckoo Cycle mining algorithm to maintain decentralization. This protocol utilizes memory-bound requirements to counteract ASIC miners, similar to others on this list. Currently, Grin remains active and has made significant progress in enhancing security, privacy, and community engagement.
10. Horizen (ZEN)
Horizen launched as Zencash in May 2017 and rebranded in 2018. Horizen is a blockchain that incorporates privacy features such as zk-SNARKs support and TLS encryption. These features make it more difficult for external sources to determine transaction details.
The project's founders, Rob Viglione and Rolf Versluis, implemented measures to help protect network decentralization and miners. As part of this strategy, they employed a hybrid consensus mechanism. This multi-layer approach is common today as it helps separate computation from verification processes.
Additionally, secure nodes stake tokens to earn rewards for providing extra network services. Staking protocols add significant value to networks as they provide users with a method to secure the network and earn low-risk passive returns without worrying about losing their original assets. Consequently, staking has become a standard feature in most fourth-generation blockchains.
Clearly, secure nodes receive rewards for protecting the network and providing additional services. This consensus structure enables networks to scale more effectively, reduce congestion, and simplify the creation of sidechains and DApps.
