Antminer Z15 Pro and Z15 are among the most Profitable miners in 2025
The crypto mining industry is known for its volatility not just in coin prices, but also in hardware profitability.
Yet, some machines continue to surprise the market. One of those is the Antminer Z15 Pro, which, as of 3rd October 2025, has re-emerged as one of the most profitable ASIC miners on the market, generating around €38 per day in mining rewards.
Even its predecessor, the Antminer Z15, is pulling in a respectable €19 per day, according to ASIC Miner Value.
A Second Life for Older Miners: The Antminer Z15 Pro and Z15
The Antminer Z15 Pro and Z15 were originally launched in 2023. But their renewed profitability shows how machine lifespan and adaptability can outlast short-term hype cycles. Many miners who invested in solid, well-built ASICs are now seeing these devices come back to life thanks to improved coin market conditions and network difficulty adjustments.
This resurgence is a reminder that mining profitability isn’t just about buying the newest machine. But about understanding market timing, energy efficiency, and long-term value.

Why These Miners Are Performing So Well?
Both the Z15 and Z15 Pro are designed for mining Equihash-based coins, such as Zcash (ZEC). With recent upticks in Zcash’s price and moderate network difficulty, miners running these devices are once again seeing strong returns.
What is Zcash?
Zcash, known for its privacy-focused blockchain, continues to maintain a loyal community and practical use cases in secure transactions. Unlike Bitcoin, which is mined with SHA-256 ASICs, Zcash’s Equihash algorithm favors a different set of hardware, giving older models like the Z15 series a chance to shine.
Disclaimer:
This article does not constitute financial or investment advice. We are simply reporting observed data and market trends regarding miner profitability in 2025. Any decisions to acquire mining hardware or exchange cryptocurrencies such as Zcash (ZEC) should be made based on individual research and risk consideration.
The Lifecycle of a Miner: Beyond the First Year
ASIC miners typically go through several profitability stages:
- Launch period – Highest returns due to low network difficulty and hype.
- Decline phase – As difficulty rises, returns fall, and newer models enter the market.
- Rebound phase – Market cycles or alternative coin profitability breathe new life into older machines.
Many miners underestimate this rebound potential. In fact, diversifying mining operations across different algorithms can help balance the risks of Bitcoin’s high competition with the flexibility of mining alternative coins like Zcash, Kadena, or Litecoin.
Investing in Longevity
Smart miners focus on machines that last, rather than chasing every new release. Factors such as:
- Energy efficiency (J/sol)
- Hardware durability
- Versatility across algorithms
- Access to affordable, renewable energy
All determine whether a machine remains profitable over time. Learn more about mining here.
A miner like the Antminer Z15 Pro demonstrates that well-built hardware paired with efficient hosting such as hydropower-based facilities in Norway — can continue to yield solid returns even two years post-launch.
