Ethereum Classic (ETC) Mining Calculator
Ethereum Classic uses the Etchash proof-of-work algorithm, a DAG-based variant of Ethash deliberately modified to remain ASIC-resistant and GPU-friendly. After Ethereum's transition to Proof-of-Stake in 2022, a large portion of GPU mining rigs migrated to ETC, temporarily increasing its network hashrate and difficulty. ETC has a capped supply of ~210 million coins and a block reward that reduces by 20% every 5 million blocks.

Best Hardware for Ethereum Classic Mining
Ethereum Classic is GPU-mined. Top-performing GPUs include the RTX 4090 (~130 MH/s, 350W), RX 7900 XTX (~110 MH/s, 300W), and RTX 3090 (~120 MH/s, 320W). For power efficiency, the RX 6600 XT achieves ~32 MH/s at only ~100W — and on the figures of 27 October 2026 it is the least unprofitable of the four, which is the honest way to rank them: all four break even only below ~$0.006/kWh. Etchash remains ASIC-resistant by design, so GPUs are the right hardware for this chain; at current difficulty that means GPUs are what you would use if the economics worked, not that they currently do.

Ethereum Classic: The Home of Ex-Ethereum GPU Miners
When Ethereum moved to proof-of-stake in September 2022, billions of dollars of GPU mining capacity needed a new home, and Ethereum Classic — running the Etchash algorithm (a modified Ethash) — absorbed a large share of it. This made ETC one of the most important GPU-mineable coins and drove its network hashrate to record highs.
For GPU miners, ETC is attractive precisely because it stays ASIC-resistant in practice (Etchash's DAG demands high-memory GPUs) and offers a liquid, widely listed reward. Cards like the RTX 3060 Ti, 3070, and AMD RX 6700/6800 remain the workhorses.
Etchash, the DAG, and GPU Memory Requirements
Etchash relies on a DAG file that grows over time; GPUs need enough VRAM to hold it, which is why 4 GB cards were phased out years ago and 6–8 GB is the practical floor today. ETC's "5M20" monetary policy reduces the block reward by 20% every 5 million blocks (about 2.2 years), so emission steadily declines.
Your ETC profitability is driven by GPU hashrate (MH/s) and power draw. Undervolting cards to cut wattage while holding hashrate is the standard tactic to improve margins at residential electricity rates.
