Ethereum Mining Is Dead, What Are the Best Coins to Mine in 2025?

PrzezMiguel Corominas Godziny

1. Introduction

Ethereum mining alternatives became essential after Ethereum switched to Proof of Stake in 2022, ending its era of GPU mining. But since the network’s long-awaited Merge in September 2022, Ethereum officially transitioned from Proof of Work (PoW) to Proof of Stake (PoS), bringing an end to ETH mining as we knew it.

For miners, this marked a turning point. The rigs, the setups, and the strategies built around Ethereum needed to find new homes, or new blockchains. Many miners powered down their GPUs, while others went on the hunt for the next best alternative. Fortunately, Ethereum may be gone from the mining scene, but it didn’t take the whole ecosystem with it.

In this article, we’ll explore the best alternatives to Ethereum mining in 2025, coins that still support PoW, offer decent rewards, and give miners a reason to stay in the game.

2. Why Ethereum Mining Ended

Ethereum’s switch to PoS was years in the making. The Merge, which went live on September 15, 2022, replaced the energy-intensive PoW system with a new validation method based on staking. In this new system, validators put up 32 ETH as collateral to secure the network, removing the need for miners entirely.

This was a monumental shift for crypto. Ethereum was the second largest PoW coin after Bitcoin, and its transition wiped out billions of dollars worth of mining hardware value almost overnight. The effects on other coins were immediate: hashpower flooded into other networks like Ethereum Classic and Ravencoin, causing massive difficulty spikes and crushing short-term profitability.

Years later, Ethereum mining is officially dead, but GPU mining isn’t. Miners who were once making profits on ETH had to find new coins that fit their rigs, power budgets, and profit expectations. The question is: which ones are worth it in 2025?

3. Key Factors When Choosing a New Coin to Mine

Not all Proof-of-Work coins are created equal. After Ethereum’s exit from the mining scene, miners quickly realized that choosing a replacement isn’t just about profitability today. The long-term potential of other hardware-compatible coins often left a lot to be desired.

Here are the most important factors to consider when picking your next coin to mine:

  • Hardware Compatibility
    Some coins favor GPUs (like Ravencoin and Kaspa), while others require ASICs (like Litecoin or Bitcoin). Before committing to a new coin, check whether your current setup can handle it efficiently. You don’t want to mine a coin that burns more electricity than it’s worth.
  • Mining Difficulty & Network Hashrate
    A coin with skyrocketing difficulty or a rapidly growing network hashrate means stiffer competition and lower rewards. Keep an eye on coins that still have room for smaller miners to earn consistent payouts.
  • Market Price and Volume
    A coin’s current price matters, but its trading volume perhaps matters even more. You need to be able to sell what you mine. Coins with healthy liquidity on major exchanges offer smoother off-ramps and more reliable pricing.
  • Block Rewards and Halvings
    How much are you actually earning per block? And when is the next reward reduction coming? Coins like Litecoin and Dash have scheduled halvings that cut rewards in half, directly affecting your bottom line.
  • Community and Development Activity
    Dead coins don’t stay profitable for long. A vibrant community and regular updates from developers are good signs that the project has staying power.
  • Merged Mining Opportunities
    Some coins, like Dogecoin, allow you to mine two chains at once, boosting your rewards without using more power. If you can take advantage of this, it’s a big plus.

4. Top Alternatives to Ethereum Mining in 2025

With Ethereum no longer mineable, altcoin miners have scattered across the ecosystem in search of new opportunities. Some networks have clearly emerged as frontrunners, offering solid rewards, and good compatibility with existing hardware.

4. Top Alternatives to Ethereum Mining in 2025

With Ethereum no longer mineable, many former ETH miners have pivoted to other Proof-of-Work coins. While none match Ethereum’s scale, several projects have carved out profitable niches for miners, especially those with the right hardware and electricity rates.

Here are some of the most compelling alternatives to Ethereum mining in 2025:

Kaspa (KAS)

  • Algorithm: kHeavyHash
  • Why Consider It? Kaspa surged in popularity post-Ethereum thanks to its GHOSTDAG protocol and rapid block times. It was for a while the most profitable option for GPU miners. However, in 2025, the network is largely dominated by ASICs, and most GPUs now run at a loss, even with cheap electricity.
  • Bonus: A unique monthly emission decay model rewarded early miners, but the window for high returns is quickly closing.

Ravencoin (RVN)

  • Algorithm: KawPoW
  • Why Consider It? Designed specifically to be ASIC-resistant, Ravencoin remains a go-to choice for GPU miners. Its focus on asset issuance and tokenization created some hype around it, and the KawPoW algorithm helps ensure a level playing field for small miners.
  • Bonus: Strong grassroots community and support across major mining pools and exchanges.

Ergo (ERG)

  • Algorithm: Autolykos v2
  • Why Consider It? Ergo blends PoW mining with a focus on privacy, scalability, and DeFi functionality. It’s one of the few coins still friendly to GPUs with 3–6 GB VRAM, making it ideal for repurposing older rigs.
  • Bonus: Lower network difficulty gives solo miners and small farms a realistic shot at consistent rewards.

Monero (XMR)

  • Algorithm: RandomX
  • Why Consider It? Monero is still the go-to for privacy-focused users and can be mined on CPUs, making it attractive for those with idle computing power or access to free electricity.
  • Bonus: Still ASIC-resistant, and one of the most decentralized coins in the space.

Litecoin (LTC)

  • Algorithm: Scrypt
  • Why Consider It? A veteran in the crypto space, Litecoin is still actively mined using ASICs. Thanks to merged mining with Dogecoin, miners earn rewards from both chains simultaneously, boosting profitability without extra energy costs.
  • Bonus: Litecoin’s liquidity, brand recognition, and stability make it one of the most dependable long-term mining plays.

Ethereum Classic (ETC)

  • Algorithm: Etchash
  • Why Consider It? ETC retains Ethereum’s original PoW structure, making it a natural landing spot for former ETH miners. Etchash was designed to maintain compatibility with older GPUs and resist ASICs built for ETH’s final mining phase.
  • Bonus: Capped supply, regular reward reductions, and support from major pools keep ETC a viable and familiar option.

4. Final Thoughts & Long-Term Outlook

Ethereum may have closed the chapter on GPU mining, but the story of Proof-of-Work is far from over. In 2025, the mining landscape is more diverse than ever, with viable alternatives offering new opportunities for seasoned miners and curious newcomers alike.

Coins like Kaspa, Ergooraz Ravencoin are carving out new communities, while more established projects like Ethereum Classic, Litecoinoraz Monero offer more reliable, long-term value. If you’re willing to do the homework, optimize your hardware, minimize your costs, and pick the right pool, mining in 2025 can still be profitable.

That said, unless you’re planning to use a cloud or colocation mining service, mining is no longer a set-it-and-forget-it game. It requires attention to detail, risk management, and a willingness to adapt. And who knows? The next breakout coin might already be mineable—you just need to be early.
