Mining is the process of creating new coins on a cryptocurrency network by solving complex math problems and processing transactions. This activity is fundamental to many blockchains, ensuring network security and decentralization.
Mining relies on the Proof-of-Work consensus algorithm: miners use their equipment’s computing power to solve cryptographic puzzles. The first to solve a block gets to add it to the chain and receives a reward—new coins plus transaction fees.
Mining demands significant hardware, electricity, and specialized devices. GPUs are popular because their architecture excels at parallel computation, making them more efficient for mining than CPUs.
Mining isn’t just about earning money—it’s essential for transaction validation, network defense, and blockchain decentralization.
GPU mining is one of the most common, accessible ways to mine crypto. Graphics processors are optimized for parallel computing, making them very effective for mining a range of crypto algorithms.
You can mine with a single GPU in a regular PC to get started, or build a dedicated mining rig with multiple GPUs. A typical rig uses a motherboard with many PCI-E slots, a strong PSU, entry-level CPU, minimal RAM, and proper cooling. Multiple rigs working together form a mining farm.
There are two main mining modes: solo and pool. Solo mining uses only your power, which means big resource needs and irregular payouts. Pool mining combines your power with others for more stable, predictable income, minus a small pool fee.
Basic steps to start mining:
Payback period is critical for mining investments. It depends on GPU price, local electricity rates, hashrate, network difficulty, and the current price of the coin you mine.
Use calculators like Whattomine to get accurate payback projections. Enter your GPU specs, hashrate, power draw, algorithm, coin, and electricity price—these tools estimate profit and ROI based on live market data.
Payback periods are constantly changing as crypto prices and network difficulty shift. Bull markets can mean ROI in months, while downturns may stretch ROI to a year or more. Always analyze market conditions before investing and be ready for volatility.
Profitability is how much profit a specific GPU can earn mining crypto. It depends on hashrate, power draw, electricity price, coin price, network difficulty, and pool fees. Net profit is mining revenue minus energy cost.
Tools like NiceHash let you compare GPU profitability across different algorithms with real-time market data, network difficulty, and coin prices.
Check your hardware’s profitability regularly and switch coins or algorithms as needed. Some miners, like NiceHash Miner, auto-switch to the most profitable algorithm in real time for hands-free optimization.
Key benefits of GPU mining:
Hardware Availability: Used GPUs are inexpensive, making mining accessible for beginners. The secondhand market offers high-performance cards at low prices.
Wide Selection: Many models from NVIDIA and AMD mean you can match your needs and budget.
Versatility: GPUs can mine many coins on various algorithms (Ethash, KawPow, Autolykos, Blake3, etc.), letting you chase the best profits.
Used Market Access: The active used market means you can find proven cards at great value, speeding up ROI.
Easy Replacement: If a GPU fails, swap it without stopping your whole farm. You can resell or repurpose GPUs for gaming, creative work, or AI.
Scalability: Grow your farm at your own pace by adding more GPUs as you earn profits.
Drawbacks to consider before you start GPU mining:
Learning Curve: You need to understand crypto markets, mining basics, and hardware/software setup for good results.
Extra Costs: Beyond GPUs, you need space, cooling, quality PSUs, and other gear—these raise your initial investment.
Space Requirements: Mining gear is noisy and generates heat—often unsuitable for homes, so you may need dedicated space with solid ventilation and power.
Technical Skills: You’ll need to assemble, configure, maintain, and repair hardware. Troubleshooting can take time.
Wear Risks: GPUs run 24/7 under heavy load, so they wear out faster. Used cards can have hidden problems.
Income Volatility: Mining profits swing with crypto prices, network difficulty, and other market forces—returns are never guaranteed.
GPUs can mine many Proof-of-Work cryptocurrencies. Which coin you mine depends on your hardware, profitability, and preferences.
The most popular GPU-mined coins include:
Ethereum Classic (ETC): Ethash algorithm, leading choice after Ethereum switched to Proof-of-Stake.
Ravencoin (RVN): KawPow, good profitability for both NVIDIA and AMD GPUs.
Kaspa (KAS): kHeavyHash, strong performance on modern GPUs.
Ergo (ERG): Autolykos v2, GPU-optimized.
Flux (FLUX): ZelHash, consistent returns.
Conflux (CFX): Octopus, good for GPUs with large memory.
You can also mine Bitcoin (SHA-256) with GPUs, but this is inefficient compared to ASICs. Dogecoin, Litecoin (via merged mining), and other altcoins are also GPU-minable.
Use tools like Whattomine and NiceHash to track profitability and switch to the best coin for your setup.
Ethereum’s shift from Proof-of-Work to Proof-of-Stake in September was a historic turning point for crypto mining, fundamentally changing the industry.
Before the switch, Ethereum was the largest GPU-mined coin, drawing millions of miners. Ethash was GPU-optimized and reliably profitable. With PoS, Ethereum mining became impossible—validators now stake coins instead of providing compute power.
This forced miners to migrate to other PoW networks, mainly:
Ethereum Classic (ETC): Still uses Ethash and absorbed many miners.
Ravencoin (RVN): KawPow algorithm, popular for its GPU optimization.
Ergo (ERG): Autolykos v2 drew miners seeking alternatives.
Beam and others: Many altcoins saw new miners chasing profitability.
This migration sharply increased hashrate and network difficulty, slashing individual miner profitability. For instance, Ethereum Classic’s network difficulty multiplied in weeks, cutting profits as competition grew.
Payback periods for GPUs grew—a few months before the switch, a year or more after, depending on energy and hardware costs.
The used GPU market was flooded as miners sold off gear, dropping prices. This helped new miners but hurt those who bought hardware just before the transition.
Ethereum’s PoS migration also pushed miners to repurpose GPUs for AI, machine learning, and cloud computing.
Where you buy your GPU impacts cost, quality, and reliability. There are two main options—buy new or used—each with its own pros and cons.
New GPUs are a reliable but more expensive choice, best for those wanting a warranty and long service life.
Pros:
Cons:
Buy new GPUs at official manufacturer stores (NVIDIA, AMD), major electronics chains, specialty PC shops, or trusted online marketplaces.
Used GPUs let you start mining with low investment, but require caution and thorough testing.
Pros:
Cons:
Where to buy used GPUs:
Ad Sites: Platforms like Avito and Youla offer a wide selection. Always verify the seller, request photos/videos, and test the card before paying if possible.
Major Marketplaces: OZON, Wildberries, and others list used hardware with condition details and reviews.

PC Markets: In-person markets let you inspect and test before buying.
Tips for buying used GPUs:
RTX 4070 and RTX 4070 Super offer excellent performance-to-power ratios and high efficiency for mining in 2024.
The RTX 4090 delivers better mining profitability thanks to higher performance and more memory, resulting in a superior ROI compared to the RTX 4080.
Daily earnings depend on GPU model and network difficulty. Under optimal conditions, a high-end GPU may yield $8–10 per day before electricity and fees. Profitability varies with power costs and market conditions.
A stable 600W or higher power supply is required, and cooling must efficiently remove heat from GPUs during continuous operation.
For Bitcoin and Ethereum, powerful cards like the RTX 3090 are best. For Dogecoin, mid-range cards such as the RTX 3060 Ti or 5700XT are suitable. Avoid top-tier cards for Dogecoin due to high cost per hashrate.
This depends on your power rates and crypto volatility. At $0.10/kWh, an RTX 4090 (450W) uses about $1.08 in electricity per day. Profitability is affected by market prices and mining difficulty.
NVIDIA GPUs are generally preferred for mining due to higher performance and broader algorithm support. AMD cards are cheaper, but most miners still choose NVIDIA.
Go for high-performance cards like the NVIDIA RTX 30 series or AMD RX 6000 series. They deliver strong hashrates and energy efficiency. Install drivers and join a reliable mining pool for steady earnings.
