The transition of Ethereum to proof-of-stake marked a pivotal shift in the crypto mining landscape — the beginning of what many now call the post-Ethereum era. With over 80% of the global GPU mining power displaced after The Merge, miners scrambled for alternatives. Today, a diverse ecosystem of GPU-friendly cryptocurrencies has emerged, offering viable income streams for those with graphics cards.
This comprehensive analysis explores 22 actively mineable cryptocurrencies that support GPU mining, including Ravencoin (RVN), Ergo (ERG), Beam (BEAM), Flux (FLUX), Conflux (CFX), and Bitcoin Gold (BTG) — evaluating their profitability, network health, algorithm sustainability, and long-term potential.
Whether you're a seasoned miner or new to decentralized mining, this guide delivers actionable insights into where GPU mining stands today — and where it’s headed.
The State of GPU Mining After Ethereum’s Merge
Before Ethereum’s shift to PoS, it consumed an estimated 110 TWh annually — more than some small countries. Its migration not only reduced environmental impact but also freed up millions of GPUs previously dedicated to ETH mining.
Suddenly, miners faced a critical question: What should I mine now?
Many turned to alternative proof-of-work (PoW) coins designed to be ASIC-resistant and GPU-friendly. These networks benefit from broader decentralization and lower entry barriers, making them ideal for home-based miners.

Deep Dive: Leading Contenders in GPU Mining
Ravencoin (RVN) – Asset Transfer Specialist
Ravencoin uses the KawPow algorithm, designed to resist ASIC dominance and favor GPUs. It focuses on peer-to-peer asset transfers — ideal for tokenizing real-world assets like gold, stocks, or collectibles.
- Average daily profit per 100 MH/s: ~$0.35–$0.50 USD
- Power efficiency: Moderate
- Community strength: Strong developer activity and active community
RVN remains one of the most stable post-Ethereum mining options due to consistent demand and regular updates.
Ergo (ERG) – Sustainable & Scalable PoW
Ergo runs on Autolykos v2, an energy-efficient algorithm emphasizing fairness and long-term decentralization.
Key features:
- Smart contracts on PoW blockchain
- Low emission rate ensures scarcity
- High resistance to ASICs
Miners report strong uptime and reliable payouts through major pools like Herominers and 2Miners.

Beam (BEAM) – Privacy-First Mining Option
Built on the Mimblewimble protocol, Beam offers confidential transactions with lightweight blockchain growth.
- Algorithm: BeamHash III (GPU-optimized)
- Block time: ~1 minute
- Mining challenge: Requires at least 4GB VRAM; higher memory bandwidth improves performance
While privacy coins face regulatory scrutiny, Beam maintains a niche among users prioritizing anonymity.
Flux (FLUX) – Decentralized Cloud Platform
Flux isn’t just a mineable coin — it's a full-stack decentralized infrastructure platform supporting dApps, nodes, and storage.
- Algorithm: ZelHash (GPU-friendly Equihash variant)
Dual earning model:
- Mining rewards
- Running full nodes ("FluxNodes")
This hybrid approach increases earning potential beyond raw hash power alone.
Conflux (CFX) – Hybrid Consensus with GPU Accessibility
Conflux combines PoW and PoS mechanisms under its unique Tree-Graph consensus.
- Octopus algorithm allows efficient GPU mining
- Backed by Chinese academic institutions and enterprise partnerships
- Growing DeFi and NFT ecosystem on-chain
CFX stands out as one of the few government-compliant public chains allowing GPU participation.
Profitability Factors Beyond Hash Rate
When assessing mining returns, consider these often-overlooked variables:
- Electricity cost: A key determinant of net profit
- Hardware efficiency: Older cards may consume more power than they generate in value
- Pool fees: Typically range from 0.5% to 2%
- Market volatility: Sudden price drops can erase gains quickly
- Network difficulty adjustments: Rising competition reduces individual rewards over time
For example, an NVIDIA RTX 3060 Ti can yield approximately:
| Coin | Est. Daily Earnings (USD) | Power Draw (W) |
|---|---|---|
| RVN | $1.80 | 120W |
| ERG | $2.10 | 110W |
| FLUX | $1.65 | 130W |
| CFX | $1.40 | 100W |
Note: Values based on average electricity rate of $0.12/kWh and June 2025 market conditions.
Frequently Asked Questions (FAQ)
Q: Is GPU mining still profitable after Ethereum moved to PoS?
A: Yes — while less lucrative than during Ethereum’s peak, many alternative coins offer sustainable profits depending on your hardware and energy costs. Efficiency-focused setups can still generate positive ROI.
Q: Which GPU models are best for mining small-cap coins?
A: Mid-range cards like the RTX 3060 Ti, RX 6700 XT, and RTX 4070 perform exceptionally well across multiple algorithms due to balanced memory bandwidth and power consumption.
Q: Are privacy coins safe to mine in 2025?
A: Mining privacy-focused coins like Beam or Zano carries minimal risk for individuals in most jurisdictions, but always verify local regulations before participating.
Q: How do I choose the right mining pool?
A: Look for pools with low fees (<1%), high uptime, transparent payout systems, and support for your chosen coin. Pools like Nanopool and Flypool remain popular choices.
Q: Can I mine multiple coins simultaneously?
A: Some multi-mining software allows split processing power across compatible algorithms, though efficiency usually decreases slightly compared to single-coin optimization.
Q: What happens if a coin gets listed on major exchanges?
A: Listings on platforms like OKX often increase visibility and price — boosting short-term profitability and encouraging more miners to join the network.
