ZCash (ZEC) remains one of the most privacy-focused cryptocurrencies in the digital asset space, leveraging advanced cryptographic techniques like zk-SNARKs to enable fully shielded transactions. While regulatory scrutiny has made purchasing ZEC more difficult on some centralized exchanges, mining continues to be a viable way to acquire this privacy coin. But is ZCash mining still profitable in 2025? Can individual miners realistically compete in today’s competitive landscape? This comprehensive guide breaks down everything you need to know about mining ZEC — from hardware selection to profitability analysis and long-term security.
Understanding ZCash Mining
ZCash operates on a Proof-of-Work (PoW) consensus mechanism, meaning new blocks are added to the blockchain through computational mining. Miners use specialized hardware to solve complex cryptographic puzzles, securing the network and earning newly minted ZEC as rewards.
The algorithm behind ZCash is Equihash, a memory-hard hashing function designed to resist ASIC dominance — at least initially. However, by 2018, manufacturers like Bitmain and Innosilicon had developed ASICs capable of efficiently mining Equihash-based coins, effectively ending the era of profitable GPU mining for ZEC.

The Economics of ZCash
ZCash has a capped supply of 21 million coins, mirroring Bitcoin’s scarcity model. Since its 2016 launch, approximately 77% of the total supply has already been mined. New coins are released through block rewards, which are halved roughly every four years.
The most recent halving occurred in May 2023, reducing block rewards from 3.125 ZEC to 1.5625 ZEC per block. The next halving is projected for late 2025, which will further reduce rewards to 0.78125 ZEC — tightening supply and potentially increasing value if demand holds steady.
This deflationary model makes early participation in mining more attractive, as each block yields fewer coins over time.
Why Mine ZCash?
While profitability is a primary motivator, there are multiple reasons to consider ZCash mining:
- Financial Incentive: Earn ZEC without direct purchase.
- Network Support: Help maintain decentralization and transaction integrity.
- Privacy Advocacy: Contribute to a project committed to financial privacy.
- Long-Term Holding: Accumulate a scarce digital asset with potential appreciation.
Even if immediate profits are slim, mining can serve as a strategic method of dollar-cost averaging into ZEC.
Preparing for ZCash Mining
Choose the Right Wallet
Before you start mining, you’ll need a secure wallet to store your earnings. ZCash supports both transparent and shielded addresses (offering full privacy). Recommended options include:
- Edge Wallet: Mobile-friendly with default shielded address support.
- Trezor Model T or One: Hardware wallets offering top-tier security for long-term storage.
Ensure your chosen wallet explicitly supports ZEC and allows access to private keys.
Selecting Mining Hardware
As of 2025, ASIC miners are the only practical option for ZCash mining. CPU and GPU mining are no longer viable due to low hash rates and high energy costs.
Top-performing ASICs for Equihash include:
- Bitmain Antminer Z15 Pro – High hash rate (~50 kH/s), ideal for serious miners.
- Innosilicon A9+ ZMaster – Competitive efficiency with moderate power draw.
- Bitmain Antminer Z9 Mini – Lower cost entry point (~$250), but less efficient.
When choosing hardware, consider not just upfront cost but also power consumption, noise levels, and cooling requirements.
Evaluating Mining Profitability
Calculate Your Potential Earnings
Profitability depends on several key factors:
- Hash rate of your equipment
- Electricity cost per kWh
- Pool fees (if applicable)
- Current network difficulty
- ZEC market price
Use online tools like WhatToMine or CoinWarz to estimate daily earnings and break-even timelines. For example:
With an Antminer Z15 Pro consuming 1,500W at $0.10/kWh, and ZEC priced at $30, estimated monthly profit could range between $40–$80 — assuming stable difficulty and no pool fees.
However, after the 2025 halving, revenues will drop by half unless price increases offset the reduction.

Setting Up Your Mining Environment
Hosting Considerations
ASIC miners generate substantial heat and noise — often exceeding 75 decibels. Running one at home may not be feasible for many users.
Consider:
- Home setup: Only viable with proper ventilation, dedicated circuitry, and soundproofing.
- Colocation services: Professional data centers host your hardware with optimized cooling, power, and maintenance — typically charging a monthly fee based on power usage.
Colocation is often more reliable and scalable for serious operations.
Initial Configuration
- Connect your ASIC to power and Ethernet.
- Locate its IP address on your network.
- Access the device dashboard (via browser).
- Input your wallet address and configure mining pool settings.
Once configured, your miner will begin contributing hash power immediately.
Joining a ZCash Mining Pool
Solo mining is nearly impossible unless you own dozens of high-end ASICs. Most miners join pools to combine hash power and receive consistent payouts.
Benefits of Pool Mining
- Regular income stream
- Reduced variance in earnings
- Access to performance dashboards
Common payout methods:
- PPS (Pay Per Share): Stable payments per valid share; lower long-term yield.
- PPLNS (Pay Per Last N Shares): Rewards based on contribution during block discovery; higher risk but better returns over time.
Popular ZCash mining pools include Flypool, Zergpool, and 2Miners. Always verify pool reliability and fee structure before joining.

Troubleshooting Common Issues
Even well-configured systems encounter problems. Watch for:
- Low hash rate: Could indicate firmware issues, overheating, or unstable power.
- Connection drops: Check Ethernet cables, router stability, and pool server status.
- High reject rates: Often caused by outdated firmware or incorrect pool settings.
Regularly update your miner’s firmware and monitor performance via the pool dashboard.
Securing Your Mined ZCash
Once you’ve accumulated a meaningful amount of ZEC:
- Withdraw earnings from the mining pool regularly.
- Transfer funds to a non-custodial wallet (e.g., Trezor or Ledger).
- Use shielded addresses when possible to preserve transaction privacy.
- Enable two-factor authentication (2FA) on all associated accounts.
Never leave large balances on exchanges or in hot wallets.

Frequently Asked Questions
Is ZCash still mineable in 2025?
Yes, ZCash remains a Proof-of-Work cryptocurrency and can be mined using ASIC hardware designed for the Equihash algorithm.
What is the best ASIC for mining ZEC?
The Bitmain Antminer Z15 Pro offers the highest efficiency and hash rate for Equihash mining as of 2025.
How much can you earn mining ZCash?
Earnings vary widely based on hardware, electricity costs, and market conditions. With current pricing and difficulty, a single Antminer Z15 Pro might generate $40–$80 per month — subject to change after the 2025 halving.
Do I need a special wallet for mined ZEC?
Yes, use a wallet that supports both transparent and shielded addresses. Edge Wallet and Trezor are highly recommended.
Should I mine solo or join a pool?
For most individuals, joining a mining pool is far more practical due to predictable payouts and lower variance.
Will ZCash mining become unprofitable after halving?
Block rewards will decrease by 50%, so profitability hinges on whether the price of ZEC rises accordingly. Efficiency improvements and low electricity costs will be crucial post-halving.
Final Thoughts
While ZCash mining is no longer accessible to casual hobbyists due to high hardware and energy demands, it remains a feasible option for those with technical knowledge and access to affordable power. With strategic planning, proper equipment selection, and smart financial modeling, mining ZEC can still offer modest returns — especially when viewed as a long-term investment strategy rather than a get-rich-quick scheme.
As network difficulty rises and block rewards diminish, staying informed and adaptable will be key to sustained success in the evolving world of cryptocurrency mining.
