Picture this: rows of humming GPUs, fans spinning like jet engines, and crypto rewards rolling in around the clock. That was the dream of Ethereum mining for years. Then, on September 15, 2022, the Merge rewrote the rules overnight, leaving every miner asking the same question — is mining Ethereum still a thing? The short answer is complicated, and the long answer is what we're covering below.

Why the Merge Killed Traditional Ethereum Mining

Before the Merge, Ethereum ran on Proof-of-Work (PoW), the same consensus mechanism Bitcoin uses. Miners raced to solve cryptographic puzzles, and whoever won got freshly minted ETH. That game ended when Ethereum swapped PoW for Proof-of-Stake (PoS), requiring validators to stake 32 ETH instead of burning electricity.

The network's energy consumption dropped by roughly 99.95%. Ethash, the mining algorithm that made GPU mining profitable, was switched off. Anyone still pointing rigs at the old chain is essentially mining a fork — like ETC (Ethereum Classic) — not Ethereum itself.

Bottom line: you can no longer mine new ETH through mining. Period.

So what CAN miners do?

  • Mine Ethereum Classic (ETC) using the same Ethash-compatible hardware
  • Stake ETH directly to earn validator rewards
  • Repurpose GPUs for other GPU-mineable coins like Ravencoin or Ergo

Legacy Mining Setup: What Used to Work (and Still Works for Forks)

If you're curious about the technical journey — or you're pivoting to ETC — here's the classic mining stack that defined an era. Understanding this history helps you spot opportunities in other PoW coins too.

The hardware backbone was always GPUs. AMD's RX 500/5000 series and Nvidia's RTX 30-series cards dominated. ASIC-resistant by design, Ethash favored memory-heavy chips, which is why graphics cards thrived where specialized miners couldn't.

  • GPU: Nvidia RTX 3060 Ti, 3070, 3080, or AMD RX 6700 XT
  • Motherboard: Multi-GPU rig board (6+ PCIe slots)
  • PSU: 80+ Gold, sized with headroom for expansion
  • Memory: 8GB+ system RAM
  • Storage: A modest SSD for OS and mining software

How to Mine Ethereum Classic (or Any Ethash Coin) Step by Step

This is the playbook miners used on ETH and now apply to ETC. Same tools, same logic, different chain.

Step 1 — Pick a wallet. You'll need a secure wallet to receive payouts. For ETC, popular choices include Trust Wallet, Exodus, or any wallet that supports Ethereum Classic addresses.

Step 2 — Choose a mining pool. Solo mining on a single GPU is a lottery. Pools combine hash power from thousands of miners and split rewards based on contribution. Look at pool fees (typically 1–3%), payout thresholds, and server locations close to you for lower latency.

Step 3 — Download mining software. Two names dominated Ethash mining: PhoenixMiner and Claymore (legacy forks). T-Rex Miner and lolMiner also support Ethash and frequently updated their compatibility.

Step 4 — Configure your batch file. Most miners use a simple .bat file with the wallet address, pool URL, and worker name. Example fields include:

  • EthDcrMiner64.exe -pool stratum+tcp://pool-address:port
  • -ewal YOUR_WALLET_ADDRESS
  • -eworker RIG_NAME
  • -epsw x

Drop in your real wallet, save the file, and launch. Hashrate should appear within seconds in the pool's dashboard.

Profitability math basics

Profit = (daily rewards × coin price) − (electricity cost + pool fees + hardware depreciation). On most Western electricity rates, single-rig mining only turns a profit during bull markets. Many modern calculators pull real-time data from pool APIs, so always plug your numbers in before you expand your operation.

Ethereum Staking vs. Mining: The 2025 Comparison

If your goal is earning ETH without trading, staking replaces mining entirely. Two paths exist:

  • Solo staking: Run your own validator with exactly 32 ETH. Max rewards, but you absorb penalties and downtime risk solo.
  • Pooled staking: Services like Lido or Rocket Pool let you stake with fractions of an ETH. Easier, with a small fee deducted from rewards.

Staking yields currently hover between 3–5% annually, depending on the protocol and the amount of ETH staked network-wide. There's no hardware noise, no electricity bill, and no heat to manage. For most newcomers, that's an upgrade over a garage full of GPUs.

Which path is right for you?

If you already own high-end GPUs and cheap electricity, pivoting to ETC or another PoW coin is viable. If you're starting fresh in 2025, staking wins on every metric — simplicity, sustainability, and predictable returns.

Key Takeaways

  • Ethereum mining ended with the Merge in September 2022. You cannot earn new ETH by mining today.
  • Miners who want to keep using their rigs should explore Ethereum Classic (ETC) or other GPU-friendly PoW coins.
  • A solid mining rig is built around a quality GPU, reliable PSU, and tuned mining software like PhoenixMiner or T-Rex.
  • Profitability hinges almost entirely on electricity cost, coin price, and pool fees — never trust calculators that ignore the power bill.
  • For most people, staking ETH is the simpler, cleaner way to put idle crypto to work in 2025.
