Dual mining has become a popular strategy among cryptocurrency miners seeking to maximize the output of their GPU rigs. By simultaneously mining Ethereum (ETH) alongside a secondary proof-of-work coin, users can generate additional income without significantly increasing power consumption or hardware strain. However, choosing the right secondary coin—such as Decred (DCR), LBRY Credits (LBRY), or PASC—can make a major difference in profitability and long-term value.
This guide explores current best practices, profitability factors, and real-world user experiences to help you decide which coin to dual mine with ETH in 2025.
Understanding Dual Mining: How It Works
Dual mining leverages underutilized computational resources on your GPU while primarily mining Ethereum using algorithms like Ethash. The secondary algorithm runs in parallel, often using different hashing methods such as Keccak, Blake2s, or Equihash, depending on the miner software and coin combination.
Popular miners like Claymore’s Dual Miner (now succeeded by forks and alternatives due to its discontinuation) allow AMD and NVIDIA GPUs to mine ETH + another coin efficiently. While historically more effective on AMD cards, modern configurations have improved dual mining performance on NVIDIA hardware as well.

Key Factors When Choosing a Secondary Coin
Not all coins are equal when it comes to dual mining. Several variables influence your final earnings:
1. Profitability vs. Long-Term Potential
Some miners prioritize immediate returns, selling secondary coins instantly. Others prefer holding assets with growth potential. For example:
- Decred (DCR): Once favored for long-term holding due to its hybrid consensus model and governance features.
- Verge (XVG): Offers high block rewards and fast transactions but lower market cap.
- LBRY Credits (now Odysee Credits): Tied to a decentralized content platform, offering niche utility.
2. Network Difficulty and ASIC Influence
The rise of ASIC miners for certain algorithms can drastically reduce GPU profitability. For instance:
- Decred’s Blake256 algorithm saw increased difficulty after Baikal released ASIC miners.
- This made GPU mining less viable over time, especially for small-scale operators.
3. Payout Thresholds and Fees
Coins like DCR historically had high minimum payout thresholds (e.g., 0.01 DCR) with transaction fees nearly half that amount—making withdrawals inefficient for small balances.
As one miner noted:
"You pay 50% in fees or wait even longer."
This inefficiency discourages participation unless you're running large-scale operations.
Comparing ETH + DCR, ETH + LBRY, and ETH + PASC
Let’s break down each option based on community feedback and technical performance.
ETH + DCR (Decred)
- Pros: Strong fundamentals, active development, governance participation.
- Cons: High difficulty due to ASIC competition; slow accumulation for small miners.
- Best for: Long-term holders with patience and low electricity costs.
Many users reported minimal returns relative to energy consumption. One user stated:
"I did not make a lot of sense to dual mine [DCR] when looking at my power consumption."

ETH + LBRY (LBRY Credits / LBC)
- Pros: Low network saturation; useful within the Odysee ecosystem.
- Cons: Limited exchange support; lower liquidity.
- Best for: Miners interested in decentralized media platforms.
While not the most profitable, LBC offers unique utility if you engage with its ecosystem.
ETH + PASC (PascalCoin)
- Pros: Designed for GPU mining; low ASIC threat; innovative blockless protocol.
- Cons: Smaller community; limited trading volume.
- Best for: Tech-savvy miners exploring alternative blockchain architectures.
PascalCoin uses the Blake2s algorithm, compatible with many dual mining setups. However, data from tools like WhatToMine often lacks updated profitability metrics, creating uncertainty.
Emerging Alternatives: Why Verge (XVG) Gained Attention
Several users shifted toward ETH + XVG (Verge) using the Blake2s algorithm via Claymore-style miners.
One user reported:
"On my 1080 Ti I can do 35 MH/s plus 1100 Verge Blake2s, totaling $3.15 per day."
While Zcash was considered more profitable individually, Verge provided solid supplementary income in dual mode. Its high block frequency allows faster balance accumulation, reducing waiting times compared to DCR.
However, always verify current market conditions—Verge’s price volatility means today’s gains could shrink tomorrow.
FAQ: Common Questions About Dual Mining in 2025
Q: Is dual mining still profitable in 2025?
A: Yes, but only with careful coin selection and efficient hardware. Profitability depends on electricity cost, GPU model, and market prices. Always use updated calculators like WhatToMine or MinerStat.
Q: Can I dual mine with NVIDIA GPUs?
A: Absolutely. While AMD cards traditionally performed better in dual setups, recent optimizations allow NVIDIA RTX series (especially 3060 Ti, 3070, and higher) to achieve strong results.
Q: Does dual mining damage my GPU?
A: No more than regular mining. Modern drivers and proper cooling minimize wear. However, sustained 100% usage will shorten lifespan over years.
Q: What is the best miner software for dual mining?
A: While Claymore is outdated, modern alternatives include PhoenixMiner, T-Rex Miner, and NBMiner—all supporting ETH + various secondary coins.
Q: Should I hold or sell the secondary coin?
A: Depends on your strategy. If you believe in the project (e.g., Decred’s governance), hold. Otherwise, auto-sell via exchanges or P2P platforms for stable USD returns.
Q: Are there tax implications for dual mining income?
A: Yes. In most jurisdictions, mined coins are taxable upon receipt. Keep records of daily earnings and fair market value for compliance.
Final Recommendation: Choose Based on Your Goals
If your main objective is immediate profit, go with the most profitable coin at any given time—use real-time comparison tools to switch dynamically.
If you're holding ETH long-term and view secondary coins as bonus income, consider:
- Selling smaller outputs automatically.
- Monitoring emerging coins with low difficulty and growing communities.
For those interested in decentralized ecosystems, coins like LBRY (Odysee) or Decred may align with your values—even if short-term gains are modest.
Ultimately, flexibility and continuous monitoring are key. Market dynamics shift rapidly; what works today may not tomorrow.
Conclusion
Dual mining remains a viable way to boost mining efficiency in 2025—but success hinges on smart decision-making. Whether you choose ETH + DCR, ETH + LBRY, or explore alternatives like Verge or SmartCash (Keccak-based), always evaluate based on real-time data, hardware capability, and personal financial goals.
As one community member wisely put it:
"It depends on your strategy."
Stay informed, stay adaptive, and maximize every hash.
