Ethereum Classic (ETC) Mining Guide

Ethereum Classic (ETC) is a decentralized blockchain platform that supports smart contract functionality, maintaining a strong commitment to immutability and decentralized governance. Since its hard fork at block height 11,700,000, ETC has transitioned to the Etchash mining algorithm, making GPU mining accessible and efficient. This guide walks you through every step of setting up and optimizing your Ethereum Classic mining operation—from hardware selection to monitoring your earnings.

Whether you're a beginner or an experienced miner, this comprehensive tutorial ensures you have the tools and knowledge to start mining ETC effectively in 2025.

Why Mine Ethereum Classic?

Ethereum Classic stands out in the crypto ecosystem for its adherence to the original Ethereum vision—decentralization without compromise. Unlike other networks that have shifted toward proof-of-stake, ETC remains a proof-of-work blockchain, offering long-term mining opportunities.

Key benefits include:

• GPU-friendly mining with Etchash (ASIC-resistant)
• Low entry barrier compared to Bitcoin mining
• Active community and consistent network upgrades
• Growing adoption in DeFi and Web3 ecosystems

👉 Discover how to maximize your mining returns with the right tools and strategies.

Step 1: Prepare Your Mining Hardware and Environment

To mine Ethereum Classic efficiently, you'll need the following:

✅ Required Equipment

• GPU (Graphics Card): Both NVIDIA and AMD GPUs are supported. Ensure each GPU has at least 4GB of VRAM.
• Mining Rig: A multi-GPU setup (typically 6–8 cards) increases hash rate and profitability.
• Power Supply Unit (PSU): High-wattage, 80+ Gold or Platinum certified PSU to handle multiple GPUs.
• Motherboard & CPU: Compatible with multiple PCIe slots; CPU requirements are minimal.
• Cooling & Ventilation: Proper airflow prevents overheating and extends hardware lifespan.

✅ Software & System Requirements

• Operating System: Windows 10/11 or Linux (Ubuntu preferred)
• Virtual Memory: Allocate 5GB per GPU (e.g., 30GB for a 6-GPU rig)
• Stable Internet Connection: Low latency improves connection to mining pools

Step 2: Choose and Install Mining Software

Several reliable mining software options support Etchash. Here are the top choices:

🔧 Open-Source & User-Friendly Miners

• NBMiner: High performance, regularly updated, supports dual mining
• GMiner: Lightweight, excellent for NVIDIA cards, low developer fee
• NTMiner (Open Source Miner): Fully open-source, developed by Chinese contributors, supports remote control and overclocking

🖥️ Mining Operating Systems

For large-scale operations, consider dedicated mining OS platforms:

• minerOS: Linux-based, allows cloud management of multiple rigs
• Wondermole (Ji Ji Mo Er): Customizable diskless system with remote monitoring
• Minerbabe OS: Tailored for GPU miners with easy batch deployment

Step 3: Register with a Mining Pool

Solo mining ETC is impractical due to high difficulty. Joining a mining pool like F2Pool increases your chances of earning consistent rewards.

How to Sign Up on F2Pool

1. Visit f2pool.com and click Sign Up
2. Complete registration using email or social login
3. After logging in, go to Account Settings > Payment Settings
4. Find your unique username—you’ll use this to configure your miner

F2Pool uses a PPLNS (Pay Per Last N Shares) reward system, which favors loyal miners with steady contributions.

Step 4: Set Up Your ETC Wallet

Before receiving mined ETC, you must have a secure wallet. Here are three trusted options:

1. Exchange Wallets

Use platforms like Binance or OKX to generate an ETC deposit address. While convenient, exchanges are custodial—meaning you don’t fully control your private keys.

⚠️ Always withdraw funds to a personal wallet for long-term storage.

2. Mobile/App Wallets

• Cobo Wallet: Non-custodial, supports ETC and other major cryptocurrencies
• Offers backup features, biometric security, and cold storage integration

3. Full Node Wallets

Run a complete Ethereum Classic node for maximum security and privacy. However, this requires significant disk space (over 500GB and growing).

Once you have your wallet address, return to F2Pool and bind it under Payment Settings to start receiving payouts.

Step 5: Configure Mining Parameters

Now it’s time to connect your rig to F2Pool using your chosen mining software.

Using GMiner

Extract the downloaded files, locate start.bat, right-click and select Edit. Replace the content with:

miner.exe --algo etchash --server etc.f2pool.com:8118 --user YOUR_USERNAME.WORKER_NAME

Replace YOUR_USERNAME with your F2Pool username and WORKER_NAME with a custom label (e.g., rig1, gpu01).

Using NBMiner

Similarly, edit the start.bat file in NBMiner:

nbminer -a etchash -o stratum+tcp://etc.f2pool.com:8118 -u YOUR_USERNAME.WORKER_NAME

Ensure there are no extra spaces or symbols—only replace the placeholder values.

💡 Pro Tip: Save multiple .bat files for different pools or worker configurations.

Step 6: Monitor Performance and Track Earnings

After launching the miner, your rig will begin submitting shares to F2Pool. Within minutes, you can monitor performance via:

• F2Pool Dashboard: Log in and switch the currency view to ETC
• Check real-time stats: hash rate, accepted shares, estimated daily earnings
• View historical payouts and network difficulty trends

You can also download the F2Pool mobile app for Android/iOS to track earnings on the go.

Common issues:

• Low Hash Rate? Check GPU drivers and virtual memory settings
• Connection Drops? Ensure stable internet and correct server port (8118)
• No Payouts? Confirm wallet binding and minimum payout threshold (0.1 ETC on F2Pool)

Frequently Asked Questions (FAQ)

Q1: Is GPU mining still profitable for Ethereum Classic?

Yes. With Etchash being ASIC-resistant, GPUs remain the most effective tool for mining ETC. Profitability depends on electricity cost, hash rate, and market price.

Q2: Can I mine ETC with 4GB GPUs?

Absolutely. The Etchash algorithm was specifically designed to support 4GB+ GPUs, allowing older models like GTX 1060/1070 to participate.

Q3: Why can't I use NiceHash or custom ASICs?

ETC officially disabled support for NiceHash and specialized mining hardware (like E3, A10) to preserve decentralization and fairness among individual miners.

Q4: How often does F2Pool pay out?

Payouts occur automatically when your balance reaches 0.1 ETC. Transactions are sent daily, depending on network conditions.

Q5: What’s the difference between ETC and ETH?

While both started together, Ethereum (ETH) moved to proof-of-stake in 2022. Ethereum Classic continues as proof-of-work, emphasizing immutability and miner inclusivity.

Q6: How do I optimize power consumption?

Use undervolting techniques through MSI Afterburner or minerOS tools to reduce power draw while maintaining high hash rates—boosting net profits.

Final Tips for Successful ETC Mining

• Regularly update your GPU drivers and mining software
• Join mining forums or Discord groups for troubleshooting
• Track electricity costs closely—profitability fluctuates with energy prices
• Consider reinvesting early earnings into additional GPUs or cooling systems

Mining Ethereum Classic in 2025 remains a viable option for individuals seeking decentralized participation in blockchain networks. With accessible hardware requirements and a resilient community, ETC offers both technical satisfaction and financial potential.
