The imminent Ethereum Proof-of-Stake (PoS) Merge raises a critical question: What's next for Ethereum miners?
This transition impacts hardware investments and mining revenues worth billions of dollars. Scheduled tentatively for the 15th–16th of next month, the Merge will render Ethereum's current Proof-of-Work (PoW) infrastructure obsolete as the network shifts to the PoS Beacon Chain.
Two Paths for Ethereum Miners Post-Merge
- PoW Fork Advocates: Primarily Chinese miners seeking to maintain Ethereum’s PoW mechanism via a fork (e.g., ETHPoW).
- ETC Migrants: Miners transitioning to Ethereum Classic (ETC).
The first option is contentious, with PoS proponents viewing it as a disruptive move. Concerns include centralized fee management (e.g., multi-signature wallets for transaction fees) and potential security risks.
The second option—mining ETC—lacks the economic scale to absorb Ethereum’s entire mining ecosystem. ETC’s market cap and revenue are ~60x smaller than Ethereum’s, requiring a 50x price surge to match current ETH mining profitability.
The ETHPoW Fork: A High-Stakes Gamble
ETHPoW, led by former ETC developer Guo Hongcai, proposes:
- A fair-launch fork with no pre-mined tokens.
- Permanent PoW mechanism.
- Reversal of EIP-1559’s fee-burning model.
- Decentralized governance with a planned team dissolution within three years.
Key concerns:
- Multi-Sig Treasury: Fees redirected to a miner/community wallet risk centralization and distrust.
- Exchange Support: Poloniex, BitMEX, and others have pledged to list ETHPoW futures, but long-term viability depends on developer and user adoption.
Lessons from Past Forks (ETC, BCH)
Historical hard forks like Bitcoin Cash (BCH) and ETC saw initial price surges but failed to sustain momentum due to:
- Lack of developer support.
- Declining hash rate and adoption.
For ETHPoW to avoid this fate, it needs robust DeFi integration and stablecoin backing—neither of which are guaranteed. Major projects (Chainlink, USDC, Tether) have already committed to PoS Ethereum.
Alternatives: ETC and Other PoW Chains
- Ethereum Classic: Antpool pledged $10M to boost ETC’s DeFi ecosystem, but its hash rate is 30x lower than Ethereum’s.
- Other PoW Coins: Networks like DOGE, RVN, and LTC are insufficient to absorb Ethereum’s hash power. Miners may distribute hash rate across multiple chains, but profits will plummet.
The Inevitable Outcome
Ethereum 2.0 marks the end of an era for GPU mining. With no clear successor chain capable of matching Ethereum’s profitability, miners face:
- Short-term gains from ETHPoW arbitrage.
- Long-term revenue declines across fragmented PoW networks.
FAQ
Q1: Can ETHPoW compete with PoS Ethereum?
A: Unlikely without developer and stablecoin support. Exchanges may enable short-term trading, but sustainability depends on adoption.
Q2: Why are major DeFi projects backing PoS?
A: PoS offers scalability and lower energy costs. Projects prioritize alignment with Ethereum’s roadmap.
Q3: What’s the best strategy for miners post-Merge?
A: Diversify hash rate across ETC, ETHPoW (if viable), and other PoW chains—but expect reduced profits.

Final Thought: The Merge underscores crypto’s evolution toward efficiency, leaving miners to adapt or exit. ETHPoW’s success hinges on overcoming centralization critiques and attracting ecosystem support—a steep challenge in PoS-dominated terrain.
