The Ethereum Classic (ETC) network has recently seen explosive growth in mining activity, with its per-unit hash rate profitability now matching that of Ethereum (ETH). According to data from QKL123, on May 6, ETC's mining return reached parity with ETH at $0.11 per unit of computational power. This milestone coincides with a dramatic surge in network hashrate—jumping to 22 terahashes per second (T), a 100% increase over just two weeks.
This sudden spike in mining interest comes amid rising speculation around ETC’s long-term role in the blockchain ecosystem, particularly as Ethereum prepares for its transition to a proof-of-stake (PoS) consensus mechanism. With ETH moving away from energy-intensive mining, many miners and investors are turning their attention to Ethereum Classic as a potential continuation of the original proof-of-work (PoW) vision.

Why Is ETC Suddenly So Profitable?
Several factors have contributed to the sharp rise in ETC’s mining attractiveness:
- Hashrate Redistribution: As Ethereum inches closer to PoS, large-scale mining operations are actively seeking alternative PoW chains where their hardware can remain productive. ETC, being one of the few major blockchains still committed to PoW, is a natural destination.
- Firmware Flexibility: Older ASIC miners like the Antminer E3, previously considered obsolete or inefficient for mainstream cryptocurrencies, can now be repurposed for ETC mining through firmware updates. This lowers the entry barrier for smaller miners and increases overall network participation.
- Market Momentum: Over the past 30 days, ETC’s price has surged nearly 7.5x, driven by both speculative trading and genuine interest in its technological positioning. Higher asset value directly translates into increased mining rewards when measured in fiat terms.
These dynamics have created a self-reinforcing cycle: rising prices attract more miners, which strengthens network security and further validates investor confidence.
The Strategic Position of Ethereum Classic
Ethereum Classic emerged after the 2016 DAO hack when a portion of the community chose to maintain the original, immutable version of the Ethereum blockchain. While ETH underwent a hard fork to reverse stolen funds, ETC adhered strictly to the principle of "code is law."
Now, years later, this ideological stance may be gaining renewed relevance.
As Ethereum transitions to PoS, critics argue that decentralization could be compromised due to high staking requirements and centralization risks around validator pools. In contrast, ETC remains fully mineable, offering an open and permissionless environment for participants worldwide.
Some industry observers believe ETC could evolve into the de facto proof-of-work counterpart of Ethereum, preserving decentralized mining access even as its larger sibling moves toward institutionalized staking.
This narrative has attracted not only retail miners but also institutional-grade mining farms looking to diversify their portfolios beyond Bitcoin.
Mining Accessibility and Hardware Considerations
One of the most compelling aspects of the current ETC mining boom is its inclusivity.
Unlike newer protocols that favor specialized or proprietary hardware, ETC remains compatible with a wide range of existing mining rigs. GPUs used for ETH mining can seamlessly switch to ETC without performance loss. More importantly, outdated ASICs such as the Bitmain Antminer E3—once deemed unprofitable—can now contribute meaningfully thanks to updated firmware that optimizes Ethash algorithm performance for ETC.
This repurposing trend extends the lifecycle of older equipment, reducing electronic waste and improving return on investment for hardware owners.
For small-scale operators, this means lower upfront costs and faster break-even timelines. For larger farms, it offers flexibility in load-balancing across multiple PoW chains based on real-time profitability metrics.
Market Performance and Investor Sentiment
Beyond mining fundamentals, ETC’s price action tells a powerful story.
In the last month alone, the cryptocurrency has appreciated approximately 750%, outperforming nearly every other top-50 digital asset. While part of this rally is attributed to macro-level crypto market momentum and speculative capital inflows, underlying demand appears robust.
On-chain analytics show increasing wallet adoption, growing exchange inflows, and tightening supply availability on secondary markets—all indicators of strong holder conviction.
Moreover, trading volume across major exchanges has spiked significantly, suggesting broadening institutional and retail interest.
However, investors should remain cautious. Rapid price appreciation often brings heightened volatility and short-term correction risks. That said, if the narrative of ETC as the “PoW version of ETH” continues to gain traction, longer-term fundamentals may support sustained value growth.

Frequently Asked Questions (FAQ)
Q: Why is ETC mining suddenly as profitable as ETH?
A: With Ethereum transitioning to proof-of-stake, miners are shifting to alternative PoW chains like ETC. Increased demand, combined with a 7.5x price surge over 30 days and repurposed mining hardware, has driven ETC’s profitability to match ETH’s current levels.
Q: Can old ASIC miners really be used for ETC?
A: Yes. Devices like the Antminer E3 can be updated with new firmware to efficiently mine ETC using the Ethash algorithm. This extends the useful life of older hardware and lowers entry costs for new miners.
Q: What happens to ETC after Ethereum completes its PoS transition?
A: Many expect ETC to become the primary proof-of-work Ethereum chain, attracting miners and users who value decentralized consensus. Its fixed monetary policy and resistance to forks enhance its appeal as a long-term store of value.
Q: Is ETC a good investment right now?
A: While past performance doesn’t guarantee future results, ETC’s alignment with decentralized mining principles and growing network activity suggest strong potential. As always, conduct thorough research and consider risk tolerance before investing.
Q: How secure is the ETC network with rising hashrate?
A: A doubling of hashrate in two weeks significantly improves network security by making 51% attacks more costly and difficult. Higher computational power enhances transaction integrity and resistance to manipulation.
Q: Where can I track real-time ETC mining profitability?
A: Various blockchain analytics platforms provide up-to-date metrics on hashrate, difficulty, and revenue per terahash. Always use trusted sources and cross-reference data for accuracy.
Looking Ahead: The Future of Proof-of-Work
While much of the crypto industry focuses on scalability and energy efficiency through PoS models, Ethereum Classic represents a different vision—one rooted in immutability, decentralization, and open participation.
As global debate continues over what truly defines a decentralized network, ETC stands as a living experiment in sustaining a community-driven, miner-secured blockchain.
Whether it becomes a major player in the next era of cryptocurrency or remains a niche alternative depends on continued innovation, developer support, and user adoption.
But one thing is clear: in a world rapidly moving toward staking and institutional control, there’s still strong demand for open, permissionless systems powered by proof-of-work.
