Cryptocurrency mining in 2025 has taken a dramatic turn, especially for those relying on GPU-based setups. As the market evolves and network difficulties shift, many home miners are reassessing the viability of their rigs. In this in-depth update, I’ll walk you through the current state of GPU mining profitability, hardware performance, and how passive income from decentralized physical infrastructure (DePIN) devices and ASICs is shaping the future of at-home crypto earnings.
The State of GPU Mining in 2025
Let’s be honest — GPU mining profits in 2025 are not what they once were. With fewer profitable coins and rising electricity costs, many miners have scaled back or shut down entirely. However, for those running optimized, low-cost setups, there’s still a narrow window of opportunity.
The primary challenge today is network difficulty. As more efficient ASICs dominate proof-of-work chains like Bitcoin and even some former GPU-friendly coins, the hash rate competition has squeezed out most GPU miners. Ethereum’s shift to proof-of-stake years ago was just the beginning; now, even coins like Ravencoin and Ergo are seeing declining GPU miner participation.
Yet, niche coins and DePIN projects are keeping GPU rigs alive. Some newer decentralized networks reward GPU-powered nodes for rendering, AI inference, or storage — creating alternative revenue streams beyond traditional hashing.

My Monthly Mining Income Breakdown
Here’s a snapshot of my current passive income from various sources:
1. GPU Mining (NVIDIA RTX 3060 Ti & 3070)
- Daily Earnings: ~$0.45 per GPU
- Monthly Total: ~$27 per card
- Net Profit After Electricity: ~$18 (at $0.12/kWh)
- Coins Mined: Mostly Kaspa (KAS) and a small amount of Zilliqa (ZIL)
Despite low returns, these cards remain operational due to their dual-use potential — they can be repurposed for AI training or gaming if mining becomes unviable.
2. ASIC Mining (Antminer S19 XP Hyd)
- Daily Earnings: ~$8.50
- Monthly Total: ~$255
- Efficiency: 18 J/TH with liquid cooling
- Coin Mined: Bitcoin (BTC)
The ASIC continues to be the workhorse of the operation. Even with Bitcoin’s halving earlier in 2024, efficient models with proper cooling and low power rates remain profitable.
3. DePIN Devices (Render Node & Filecoin Miner)
- Monthly Earnings: ~$60 combined
- Hardware Used: RTX 3080 + 64GB RAM + 10TB NVMe
- Networks: Render Network and Filecoin
DePIN is where the real innovation lies. Instead of just hashing, your hardware contributes to real-world computing tasks — and gets rewarded for it. This model offers more sustainable long-term potential than traditional mining.
Key Challenges Facing Miners in 2025
🔹 Rising Energy Costs
Electricity prices have increased across many regions, making high-wattage GPUs harder to justify. A single RTX 3070 pulling 220W continuously can cost over $60/month in power alone — often exceeding mining rewards.
🔹 Limited Profitable Coins
Very few coins remain GPU-mineable with positive ROI. Kaspa, Dogecoin (via merged mining), and Monero are among the last viable options — but even these require careful optimization.
🔹 Hardware Wear and Longevity
Running GPUs 24/7 leads to thermal degradation. Fans wear out, VRAM overheats, and solder joints weaken. Regular maintenance is now a necessity, not a luxury.
Optimizing for Profitability: What Works Now?
To stay profitable, I’ve implemented several key strategies:
- Undervolting GPUs to reduce power draw by 25% without significant hashrate loss.
- Using Linux-based mining OS (like HiveOS) for better stability and remote monitoring.
- Scheduling mining during off-peak hours to take advantage of lower electricity rates.
- Diversifying into DePIN to utilize idle compute cycles.

Frequently Asked Questions (FAQ)
Q: Is GPU mining still worth it in 2025?
A: For most people, no — unless you have access to cheap electricity (<$0.08/kWh) or are using existing hardware with no upfront cost. However, repurposing GPUs for DePIN or AI tasks can extend their value.
Q: What’s the best coin to mine with a GPU right now?
A: Kaspa (KAS) is currently one of the most profitable due to its DAG-based algorithm and active community. Monero (XMR) remains a privacy-focused option with steady demand.
Q: Should I switch from GPU to ASIC mining?
A: If you're serious about long-term mining, yes. ASICs offer vastly superior efficiency for Bitcoin and other major coins. Just ensure you have adequate cooling and power infrastructure.
Q: Can DePIN replace traditional mining?
A: Not fully — but it’s a promising evolution. DePIN rewards useful work (like rendering or storage), making it more sustainable and aligned with real-world utility.
Q: How do I track mining profits accurately?
A: Use tools like Kryptex, MinerStat, or Hiveon API to monitor real-time earnings, power consumption, and net profit after electricity.
The Future of Home Mining
While traditional GPU mining fades, the broader concept of decentralized home-based earning is growing stronger. DePIN networks, staking pools, and hybrid mining-farming models are opening new doors.
For example:
- Rent out your GPU for AI inference via platforms like Render or io.net.
- Run a lightweight node for projects like Storj or Akash.
- Combine solar power with battery storage to offset energy costs.
These approaches don’t just generate crypto — they contribute to a decentralized internet infrastructure.

Final Thoughts
Mining in 2025 is no longer about stacking GPUs and hoping for the best. It’s about adaptation, efficiency, and diversification. The era of easy passive income from a basement rig is over — but smarter, more strategic approaches are emerging.
Whether you’re holding onto legacy mining gear or exploring next-gen DePIN networks, the key is staying informed and flexible. The blockchain ecosystem rewards innovation — not nostalgia.
As always, do your own research, monitor your costs closely, and never invest more than you can afford to lose.
The future of decentralized earning isn’t dead — it’s just evolving.
