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. Etchash ASICs exist but GPU rigs remain competitive due to the algorithm's design.
