Following Ethereum's transition to proof-of-stake, GPU mining has largely become obsolete. While some miners continue using graphics cards for alternative cryptocurrencies, their presence is now minimal.
Key Findings: The Exodus of GPU Miners
- 70%+ Exit Rate: Luxor Mining Pool's CEO reported that over 70% of Ethereum GPU miners sold their equipment post-upgrade.
- 20–30% Migrated: Remaining miners shifted to other networks, primarily Ethereum Classic (ETC), but profitability is nonexistent.
- Unviable Earnings: Even with high-efficiency GPUs and ultra-low power costs (~3¢/kWh), ETC mining revenue fails to cover operational expenses.
GPU Mining’s Niche Future
Why Large-Scale Mining Faded
- Ethereum’s Dominance Gone: Without ETH’s profitability, industrial-scale GPU mining is no longer sustainable.
Small Coins, Big Challenges: Networks like ETC, Ravencoin (RVN), and Conflux (CFX) suffer from:
- Low token prices deterring new miners.
- Soaring difficulty rates from sudden miner influxes, slashing individual rewards.
ETHW: A Temporary Lifeline?
Some miners pivoted to EthereumPoW (ETHW), hoping to replicate past profits. However, if ETHW’s price declines, this stopgap will mirror ETC’s unprofitability.

Industry Implications
- NVIDIA’s Reality Check: The era of crypto-driven GPU demand is over. Mining-related price surges won’t return.
- Advice to Miners: Liquidate hardware now; prolonged mining risks deeper losses.
FAQs
Q: Is GPU mining still profitable in 2025?
A: No. Major coins like ETC operate at a loss, and small networks offer negligible returns.
Q: What’s driving ETHW’s current mining activity?
A: Short-term hype. Sustainability depends on its market price—likely to fall as novelty fades.
Q: Should I invest in mining GPUs?
A: Avoid. Resale value drops daily, and ROI is unachievable.

Final Thoughts
The data is clear: GPU mining’s golden age has ended. Miners exiting or clinging to unprofitable chains face the same outcome—financial unsustainability. For those still active, diversification into non-mining crypto ventures is critical.
