Ethereum’s long-anticipated transition to Proof-of-Stake (PoS) marked a pivotal moment in the blockchain world—especially for GPU miners who once relied heavily on mining ETH using graphics cards. With Ethereum no longer supporting Proof-of-Work (PoW), many miners are asking: what cryptocurrencies can they mine now? The good news is that the shift doesn’t mean the end of GPU mining. In fact, numerous profitable alternatives remain available.
This guide explores the best post-Ethereum mining options, key factors to consider when switching coins, and how miners can maximize returns in the evolving crypto landscape.
The End of Ethereum PoW Mining: What Changed?
In 2025, Ethereum fully completed its transition from PoW to PoS through The Merge and subsequent network upgrades. This eliminated block rewards for miners and transferred validation responsibilities to stakers. As a result:
- GPU mining for ETH is no longer possible.
- Miners had to either sell their rigs, repurpose them, or pivot to other PoW-based cryptocurrencies.
- The global hashrate previously dedicated to Ethereum migrated across various alternative blockchains.
Despite this change, the demand for GPU-mined coins remains strong, thanks to decentralized networks that still rely on PoW consensus mechanisms.

Top Cryptocurrencies GPU Miners Can Switch To
After ETH’s PoS transition, several blockchain projects saw a surge in mining activity. These networks offer solid decentralization, active communities, and ongoing development—making them viable long-term options.
1. Ethereum Classic (ETC)
As Ethereum’s original chain, Ethereum Classic continues to operate under a PoW model. It shares similarities with early Ethereum and maintains compatibility with many existing mining tools.
- Algorithm: Ethash (same as pre-Merge ETH)
- GPU-friendly: Yes
- Why it's popular: Familiar setup for former ETH miners; low entry barrier
Many miners seamlessly transitioned from ETH to ETC since their rigs required minimal reconfiguration.
2. Zcash (ZEC)
Zcash focuses on privacy and uses the Equihash algorithm, which favors GPUs over ASICs—making it ideal for individual miners.
- Algorithm: EquihashBWT (GPU-optimized)
- Privacy features: Shielded transactions
- Mining software: EWBF, GMiner
ZEC has maintained consistent developer support and exchange listings, offering both stability and potential upside.
3. Monero (XMR)
Monero is one of the most privacy-centric cryptocurrencies and uses the RandomX algorithm, designed specifically to resist ASIC dominance.
- Algorithm: RandomX
- CPU & GPU compatible
- Strong anti-centralization focus
While Monero is often associated with CPU mining, modern GPUs can still contribute effectively—especially in multi-threaded setups.
4. Ravencoin (RVN)
Ravencoin specializes in asset creation and transfer, making it attractive for niche use cases like tokenized assets and collectibles.
- Algorithm: KawPow (a variant of ProgPoW)
- Designed to be ASIC-resistant
- Active community and regular updates
KawPow performs well on modern GPUs, particularly NVIDIA cards, providing steady returns depending on market conditions.
5. Dogecoin (DOGE) + Litecoin (LTC) – Merged Mining
Though Dogecoin and Litecoin primarily use Scrypt-based ASIC mining, there are emerging gateways for indirect participation via merged mining pools or hybrid protocols.
While not directly GPU-mineable anymore, some platforms allow partial involvement through auxiliary chains or staking derivatives.
Factors to Consider When Choosing a New Mining Coin
Switching coins isn’t just about picking the highest-paying option—it involves evaluating multiple variables to ensure long-term sustainability.
Electricity Costs
High-power consumption is inherent to GPU mining. If your electricity rate exceeds $0.12/kWh, profitability drops significantly unless you're mining high-value or low-difficulty coins.
👉 Calculate your mining ROI with real-time profit estimators.
Hardware Compatibility
Ensure your current rig supports the target coin’s algorithm. For example:
- Ethash coins work best with AMD/NVIDIA GPUs (6GB+ VRAM)
- Equihash requires substantial RAM and VRAM
- RandomX favors CPUs but scales with GPU parallelism
Upgrading memory or cooling systems may extend your rig’s lifespan.
Network Difficulty and Volatility
Mining profitability fluctuates due to:
- Hashrate influx from displaced ETH miners
- Market price swings
- Developer roadmap changes
Monitor difficulty trends and coin fundamentals before committing long-term.
Frequently Asked Questions (FAQs)
Q: Can I still use my old Ethereum mining rig?
Yes. Most modern GPU rigs can mine alternative PoW coins like ETC, ZEC, or RVN with minimal configuration changes. Just update your mining software and point it to a new pool.
Q: Is GPU mining still profitable in 2025?
It depends on electricity costs, hardware efficiency, and chosen coin. While less lucrative than during the ETH boom, strategic mining on undervalued or emerging PoW chains can yield positive returns—especially if you already own the equipment.
Q: Are there any new GPU-mineable coins launching?
Yes. Several new projects launch each year with fair-launch models and ASIC resistance. Examples include Flux (ZEL), Nexa (NEXA), and Firo (FIRO). Always research team credibility and tokenomics before investing time or power.
Q: Should I sell my rig or keep mining?
If your rig is outdated (e.g., GTX 10-series or older), selling might be more practical. However, newer rigs (RTX 30/40-series) retain resale value and can mine profitably at scale—especially with access to cheap power.
Q: How do I choose the most profitable coin to mine?
Use real-time calculators like WhatToMine or MinerStat. Input your rig specs, power cost, and internet speed to compare estimated daily earnings across different coins.
Q: Can I automate switching between coins based on profitability?
Yes. Platforms like NiceHash automatically direct your hash power to the most profitable algorithm at any given time—simplifying decision-making and maximizing returns without manual intervention.
Maximizing Returns in the Post-Ethereum Era
The end of Ethereum PoW wasn’t the death of GPU mining—it was an evolution. Successful miners adapt by:
- Diversifying across multiple algorithms
- Joining efficient mining pools
- Leveraging cloud-based monitoring tools
- Exploring dual-mining opportunities (e.g., T-Rex + GMiner combos)
Additionally, integrating trading strategies—such as selling mined coins during price spikes or converting into stablecoins during bear markets—can enhance financial resilience.
👉 Start optimizing your mining strategy with advanced analytics tools.
Final Thoughts
While Ethereum’s shift to PoS reshaped the mining ecosystem, it opened doors for innovation and diversification. Coins like Ethereum Classic, Zcash, Monero, and Ravencoin continue to thrive under PoW models, offering real opportunities for GPU miners willing to adapt.
By understanding algorithm compatibility, monitoring market dynamics, and leveraging automation tools, miners can not only survive but thrive in this new era of decentralized computing.
