End of Ethereum Mining: When It Ends and What to Mine Next with GPU

·

The era of Ethereum mining is coming to a definitive close. As the blockchain transitions from Proof-of-Work (PoW) to Proof-of-Stake (PoS), GPU miners worldwide face a pivotal moment in cryptocurrency history. This shift—commonly known as "The Merge"—marks the end of an era for GPU-based mining on Ethereum and raises crucial questions: When will Ethereum mining stop? What should you mine next with your GPU? This guide breaks down the transition, what it means for miners, and how to pivot profitably in the post-Ethereum mining landscape.

When Does Ethereum Mining End?

Ethereum developers have set a specific trigger for the PoW-to-PoS transition: Total Terminal Difficulty (TTD). TTD is a cumulative metric that increases with every new block mined. Once it reaches 58,750,000,000,000,000,000,000, the Merge will occur.

Current TTD: 57,569,366,816,331,680,186,368
Target TTD: 58,750,000,000,000,000,000,000
Estimated Date: September 14, 2025

This date is highly accurate, though minor fluctuations could occur if the network hashrate changes dramatically. A developer-led delay is possible but considered extremely unlikely. Once the threshold is met, Ethereum mining will cease instantly.

How the Merge Works: No More Ethereum Mining

Contrary to rumors, Ethereum mining will not continue after The Merge. The network will no longer accept PoW-mined blocks. The difficulty bomb and other mechanisms ensure a hard cutoff—mining stops completely.

This means:

The transition is irreversible and marks the end of one of the most profitable mining opportunities in crypto history.

What Happens to Mining Pools Like 2Miners?

Mining pools such as 2Miners will operate until the exact moment TTD is reached. At that point:

Payouts will be processed normally until The Merge. Afterward:

Note: Final BTC or NANO payouts may be delayed if exchanges like Binance or Kraken temporarily suspend ETH-related transactions during the transition.

What to Mine When Ethereum Mining Stops

With Ethereum’s hashrate—once the largest in PoW—going offline, miners must quickly adapt. Fortunately, several profitable alternatives remain viable for GPU mining in 2025.

Top Alternatives for GPU Miners

Use tools like 2CryptoCalc to compare profitability based on your hardware and energy costs.

Pro Tip: After The Merge, expect volatility in coin profitability as thousands of miners shift simultaneously. Monitor real-time data and be ready to switch.

Switching to Ethereum Classic (ETC) Mining

Ethereum Classic is the most natural successor due to its similar Ethash-based algorithm—now modified to Etchash.

Configuration Changes:

For ASIC users (e.g., Innosilicon A10), firmware updates may be required.

NiceHash Setup:

Custom pool name: 2Miners ETC  
Algorithm: ETCHash  
Stratum: etc.2miners.com:1010  
Username: YOUR_WALLET_ADDRESS  
Password: x

Switching to Ravencoin (RVN) Mining

Ravencoin uses the KawPow algorithm, optimized for GPUs and resistant to ASIC dominance.

Configuration Changes:

NiceHash Setup:

Custom pool name: 2Miners RVN  
Algorithm: KAWPOW  
Stratum: rvn.2miners.com:6161  
Username: YOUR_WALLET_ADDRESS  
Password: x
Note: RVN mining on 4GB GPUs is expected to remain feasible until mid-2025.

Switching to Ergo (ERG) Mining

Ergo uses Autolykos v2, a memory-hard algorithm ideal for consumer GPUs.

Configuration Changes:

NiceHash Setup:

Custom pool name: 2Miners ERG  
Algorithm: Autolykos  
Stratum: erg.2miners.com:8888  
Username: YOUR_WALLET_ADDRESS  
Password: x

Could EthereumPoW (ETHW) Be an Option?

A fork project called EthereumPoW (ETHW) aims to preserve the PoW chain post-Merge. While technically possible, its long-term viability is uncertain:

2Miners is evaluating ETHW integration and will update miners if support is added.

What to Mine with GPU in 2025

The days of “set and forget” Ethereum mining are over. In 2025, profitability depends on:

Best Options for Nvidia GPUs

Nvidia cards offer superior algorithm flexibility:

Use 2CryptoCalc to compare earnings across coins based on your specific model.

Best Options for AMD GPUs

AMD cards remain cost-effective but consume more power:

Important: Linux offers better performance for 4GB cards mining RVN due to lower memory overhead.

Frequently Asked Questions (FAQ)

Q: Does Ethereum mining stop completely after The Merge?
A: Yes. The network will no longer accept PoW blocks. Mining ETH will be impossible.

Q: Can I keep using my Ethereum wallet for ETC or RVN?
A: For ETC, yes—same address format. For RVN and ERG, you need new wallets.

Q: Will my GPU become useless after September 14?
A: No. Many coins like ETC, RVN, and ERG are still profitable with modern GPUs.

Q: How soon should I switch my mining rig?
A: Prepare configurations in advance. Switch immediately after The Merge to avoid downtime.

Q: Is cloud mining still viable post-Ethereum?
A: Only if energy costs are low. Most cloud contracts were built around ETH—review terms carefully.

Q: Can I mine multiple coins at once?
A: Not effectively. Most profitable strategy is switching dynamically based on real-time profitability.

The end of Ethereum mining isn’t the end of GPU mining—it’s a transformation. By adapting quickly and choosing the right coins, miners can continue earning in this new chapter of blockchain evolution.
