As 2018 approached, miners sought the best coins to mine with affordable hardware and reasonable power costs. This period favored algorithms that favored GPUs over ASICs, opening opportunities for hobbyist miners.
Profitability depended on coin difficulty, energy prices, and hardware efficiency, making careful benchmarking essential before committing to any mining setup.
| Coin | Algorithm | Typical Hardware | Monthly Est. Profit (USD) |
|---|---|---|---|
| Ethereum | Ethash | AMD RX 580 / Nvidia GTX 1070 | 180 260 |
| Ethereum Classic | Ethash | AMD RX 580 / Nvidia GTX 1060 | 90 130 |
| Zcash | Equihash | AMD RX 580 / Nvidia GTX 1060 | 70 110 |
| Monero | RandomX | CPU (Ryzen 5 / i7) | 40 70 |
| Beam | Equihash | Nvidia GTX 1060 / RTX 2060 | 50 80 |
Mining Hardware Strategies in 2018
GPU Configurations and Cost Efficiency
GPU mining dominated in 2018 because multiple algorithms remained resistant to ASIC dominance. Builders focused on hash rate per watt and budget, often choosing mid-range cards such as RX 580 and GTX 1060 for balanced performance.
Overclocking and undervolting provided extra margins, allowing miners to increase profits without significant additional hardware investment when paired with good cooling solutions.
Algorithm Landscape and Coin Choices
Ethash and Memory-Hard Competitors
Ethash-powered coins like Ethereum and Ethereum Classic remained popular due to strong liquidity and established exchanges. Equihash-based options such as Zcash and Beam attracted miners seeking ASIC-resistant designs with decent reward consistency.
Choosing between these algorithms meant considering DAG file sizes, as Ethereum's dataset grew into several gigabytes, requiring more video memory and reliable power supplies.
Operating Systems and Pool Integration
Linux vs Windows Mining Setups
Many experienced miners preferred Linux for stability and lower overhead, while Windows remained accessible for beginners thanks to better driver support and mining software dashboards.
Pools such as Ethermine, Nanopool, and Zcash mining pools offered low-latency connections, transparent fee structures, and stats tracking, which were critical for optimizing long-term returns.
Profitability Considerations in 2018
Electricity, Difficulty, and Revenue Streams
Electricity price was often the largest variable cost, making location a decisive factor in profitability. Regions with subsidized power or cooler climates reduced both energy bills and cooling requirements.
Difficulty spikes during 2018 shifted rewards toward larger mining operations, yet well-tuned farm rigs and efficient pooling strategies still delivered positive cash flow for many participants.
Key Takeaways for 2018 Mining Planning
- Benchmark hash rate and power consumption before purchasing hardware in bulk.
- Prioritize coins with strong market depth to ensure smooth conversion to fiat.
- Factor in VRAM capacity and DAG file growth when selecting GPUs.
- Monitor difficulty trends and adjust pool participation accordingly.
- Secure reliable cooling and power infrastructure to avoid costly downtime.
FAQ
Reader questions
