The Ethereum network's transition to Proof-of-Stake (PoS) marks a pivotal moment for cryptocurrency mining. This upgrade fundamentally alters how the blockchain operates, moving away from energy-intensive Proof-of-Work (PoW) mining toward a staking model where validators secure the network by locking up ETH.
The End of an Era for Ethereum Miners
Traditional GPU miners face unprecedented challenges as Ethereum completes its "Merge" upgrade. The PoS mechanism rewards investors who stake their Ethereum holdings, effectively making GPU mining obsolete for ETH. While some mining groups have explored fork possibilities, successful alternatives remain unlikely in the current landscape.

F2Pool's Strategic Decision
As the largest Ethereum mining pool globally, F2Pool (commonly known as "Fish Pool") has announced it will cease Ethereum mining operations on September 20, 2022. This decision aligns with:
- The expected September 10-20 PoW termination window
- The pool's commitment to smooth transition for miners
- Ongoing support for alternative mineable coins
Key dates for miners:
- Final payouts processed post-Merge
- Wallet verification deadline: September 15
- Last day of ETH mining: September 20
Market Shifts and Mining Implications
Ethereum's hashrate has shown significant decline since June 2022, when the upgrade timeline became official. This reflects:
- Mass GPU sell-offs by miners exiting the space
- Hashrate redistribution to other mineable coins
- Secondary market risks from flooded used hardware
Critical Considerations for Buyers
The used GPU market requires extreme caution due to:
- Potential ex-mining cards with degraded performance
- Frankencards assembled from multiple damaged units
- Lack of warranty coverage on most mining hardware

Alternative Mining Options Post-Ethereum
While Ethereum mining ends, F2Pool will continue supporting:
- Ethereum Classic (ETC)
- Ravencoin (RVN)
- Conflux (CFX)
| Coin | Algorithm | Current Profitability |
|---|---|---|
| ETC | Etash | Moderate |
| RVN | KawPow | Fluctuating |
| CFX | Octopus | Emerging |
Frequently Asked Questions
Q: Can I still mine Ethereum after the Merge?
A: No, Ethereum will completely transition to PoS, making GPU mining impossible on the main chain.
Q: What happens to my unpaid mining balance in F2Pool?
A: All balances will be paid out normally after the Merge, provided your wallet address remains accessible.
Q: Are other major pools also shutting down ETH mining?
A: Yes, most reputable pools including SparkPool and Ethermine have announced similar plans.
Q: Is Ethereum Classic a viable alternative?
A: While ETC continues PoW mining, its market cap and liquidity are significantly smaller than ETH's.
Q: How can I verify if a used GPU was a mining card?
A: Look for signs of 24/7 operation including fan wear, thermal paste condition, and BIOS modifications.
Q: Will GPU prices return to normal after the Merge?
A: Market corrections are expected, but high-end cards may retain value for gaming and creative workloads.
