How to Mine Ethereum Classic

Ethereum Classic (ETC) is the original Ethereum blockchain that continued on its original path following the 2016 DAO hack. While Ethereum (ETH) has since transitioned to a proof-of-stake model, Ethereum Classic remains a proof-of-work network, making it one of the few major cryptocurrencies still mineable with GPUs. As more users revisit mining in 2025, a common question arises: How can you mine Ethereum Classic today?

What Is Ethereum Classic?

Ethereum Classic is a decentralized, open-source blockchain that maintains Ethereum’s original architecture and commitment to immutability. After the DAO hack in 2016, the Ethereum community split: Ethereum (ETH) chose to reverse the hack through a hard fork, while Ethereum Classic (ETC) kept the chain’s original history intact.

ETC uses the Ethash mining algorithm and follows the proof-of-work consensus mechanism, similar to pre-Merge Ethereum. This makes it accessible to GPU miners and attractive to users who value censorship resistance and the “code is law” philosophy.

Why People Mine Ethereum Classic

There are several reasons miners choose to support and mine ETC:

  • Support for GPU Mining: Unlike Ethereum (now PoS), Ethereum Classic still uses Ethash, allowing individuals with GPUs to contribute to network security and earn block rewards.
  • Lower Competition: After Ethereum transitioned to proof-of-stake, many miners turned to other blockchains. ETC presents a less competitive environment for GPU mining in comparison to ETH pre-Merge.
  • Decentralized Values: Ethereum Classic has remained committed to principles like immutability, transparency, and open participation, making it a meaningful choice for miners who support these ideals.

How to Mine Ethereum Classic

Mining ETC can be done at home with the right equipment and setup. Here’s a step-by-step guide:

1. Choose Your Hardware

ETC mining is typically done with GPUs. While ASIC miners are available, many individuals prefer GPUs such as:

  • NVIDIA GTX 1660 Super
  • RTX 3060 Ti or better
  • AMD RX 5700 or similar

Look for GPUs with at least 4–6 GB of VRAM for stable performance.

2. Download Mining Software

Once your hardware is ready, install mining software that supports the Ethash algorithm. Popular choices include:

  • PhoenixMiner
  • GMiner
  • lolMiner

Make sure to download software from official sources to avoid malware.

3. Join a Mining Pool

Solo mining is technically possible, but mining pools increase your chances of earning steady rewards. Recommended ETC mining pools include:

  • 2Miners
  • Ethermine
  • F2Pool

Check each pool’s payout methods, minimum thresholds, and server locations for optimal performance.

4. Configure Your Miner

Edit the configuration or batch file for your mining software. You’ll typically need to input:

  • Mining pool URL
  • Your ETC wallet address
  • A worker name (any identifier for your mining rig)

Example (PhoenixMiner configuration):
PhoenixMiner.exe -pool etc.2miners.com:1010 -wal YOUR_ETC_WALLET.WORKER_NAME -pass x

5. Start Mining

Run the miner and monitor its performance. You should see metrics like:

  • Hash rate (measured in MH/s)
  • Accepted shares
  • Power usage and temperature

Ensure your rig remains stable and doesn’t overheat.

Before mining Ethereum Classic, prepare the following essentials:

  • ETC Wallet: Choose a wallet that supports ETC, such as Trust Wallet, Atomic Wallet, or a hardware wallet like Ledger.
  • Stable Internet Connection: Mining requires continuous uptime and low-latency connectivity.
  • Mining Software: Pick software compatible with your GPU and operating system.
  • Cooling and Ventilation: Mining generates significant heat. Proper airflow or external cooling solutions are essential for long-term use.

Ethereum Classic remains one of the last major proof-of-work cryptocurrencies in 2025, offering an accessible entry point for home miners. With the right hardware, mining software, and pool configuration, users can contribute to the ETC network and potentially earn rewards.

However, it’s important to account for practical considerations: electricity costs, hardware depreciation, network difficulty, and pool reliability. As with any blockchain activity, always verify settings and be cautious with downloads.

Mining ETC is a technical but approachable process, and with preparation and monitoring, it can be a worthwhile experience for those interested in decentralized infrastructure and GPU-based mining.
