What Is Zcash?
Zcash (ZEC) is a privacy-focused cryptocurrency that uses a cryptographic proof system called zk-SNARKs to allow users to shield their transactions from public view. Unlike Bitcoin, where every transaction is fully visible on a public ledger, Zcash lets you choose between transparent transactions (like Bitcoin) and fully shielded ones that reveal nothing about sender, receiver, or amount.
Zcash launched in October 2016 and uses the Equihash proof-of-work algorithm, which was originally designed to be ASIC-resistant. However, by 2018 the Bitmain Antminer Z series made ASIC mining dominant. Today, dedicated Zcash ASICs produce far more hashes per watt than any GPU, making them the practical choice for serious miners.
Can You Still Mine Zcash Profitably?
In 2025, Zcash ASIC mining remains viable for those with access to electricity below $0.08/kWh. The key metrics to understand:
- Network hashrate: ~9 GH/s (Equihash Sol/s)
- Block reward: 3.125 ZEC (after the November 2024 halving)
- Block time: ~75 seconds (~1,152 blocks/day)
- Daily network emissions: ~3,600 ZEC/day shared among all miners
A single Bitmain Antminer Z15 Pro (620 KSol/s, 3,300W) earns roughly 0.038–0.042 ZEC/day at current difficulty. At $40 ZEC that's ~$1.60/day revenue. Whether that's profitable depends entirely on your electricity rate and hardware cost.
What Hardware Do You Need?
For profitable Zcash mining in 2025, ASIC miners are the only practical option. GPUs are roughly 100Ã- less efficient per watt. The main ASIC options are:
| Miner | Hashrate | Power | Efficiency |
|---|---|---|---|
| Antminer Z15 Pro | 620 KSol/s | 3,300W | 188 Sol/W |
| Antminer Z15 | 420 KSol/s | 1,510W | 278 Sol/W |
| Antminer Z15J | 270 KSol/s | 970W | 278 Sol/W |
For beginners, the Z15 or Z15J offers the best efficiency and a lower upfront cost compared to the Z15 Pro. The Z15 Pro's raw hashrate is higher, but it draws significantly more power — you'll need dedicated 20A circuits and proper ventilation.
Electricity: The Most Critical Factor
Mining profitability is dominated by electricity cost. Here's what you need to know before spending any money on hardware:
- Find your electricity rate on your last utility bill (in $/kWh)
- Run the numbers in our profitability calculator before buying hardware
- At $0.10/kWh, an Antminer Z15 costs ~$3.62/day in electricity alone
- At $0.06/kWh, the same miner costs ~$2.17/day — potentially profitable
- At $0.12/kWh or above, you will almost certainly mine at a loss with current ZEC pricing
The break-even electricity rate for an Antminer Z15 at $40 ZEC is approximately $0.083/kWh. Use the calculator to find your specific numbers.
Choosing a Mining Pool
Solo mining Zcash is practically impossible for a single miner — the probability of solving a block alone is vanishingly small. Pool mining combines your hashrate with thousands of other miners and pays you a proportional share of every block found. Recommended beginner pools:
- F2Pool — Largest Zcash pool by hashrate. Reliable payouts, 2.5% fee, minimum payout 0.1 ZEC.
- Viabtc — Long-established, 4% fee with rebate system, strong uptime record.
- Poolin — Competitive 2% fee, good dashboard for beginners.
- Luxor — North American-focused, transparent fee structure.
For most beginners, F2Pool is the safest starting point due to its size (more consistent payouts) and well-documented setup guides.
Setting Up a Zcash Wallet
Before you can receive ZEC, you need a wallet address. Options for miners:
- Zashi (iOS/Android) — Official Zcash Foundation wallet, supports shielded addresses. Best for privacy-conscious miners.
- Ywallet (iOS/Android/Desktop) — Fast sync, supports transparent and shielded addresses, open source.
- Ledger hardware wallet — Best for long-term cold storage. Supports ZEC transparent addresses.
- Exchange address (Coinbase, Kraken) — Convenient but you don't control the private keys. Acceptable for testing but not for long-term storage.
For pool mining, you'll typically use a transparent (t-address) since most pools don't support shielded withdrawals. You can later shield your ZEC using Zashi or Ywallet.
The Mining Setup Flow
Once you have hardware, a pool account, and a wallet address, the setup sequence is:
- Power on the ASIC and connect it to your local network via Ethernet
- Find its IP address from your router's DHCP list
- Open the miner's web interface (e.g., 192.168.1.100)
- Navigate to Miner Configuration → Pool Settings
- Enter Pool 1 URL (e.g.,
stratum+tcp://zec.f2pool.com:3333), worker name (e.g.,youruser.worker1), and your pool password - Save and restart. Within 2–5 minutes your miner appears in the pool dashboard.

What Are Realistic Earnings?
Based on May 2025 network conditions:
| Hardware | Daily ZEC | Daily Revenue (@ $40) | Elec Cost (@ $0.07) | Net/Day |
|---|---|---|---|---|
| Z15 Pro (1 unit) | ~0.040 | ~$1.60 | $5.54 | -$3.94 |
| Z15 (1 unit) | ~0.027 | ~$1.08 | $2.54 | -$1.46 |
| Z15 (1 unit @ $0.05) | ~0.027 | ~$1.08 | $1.81 | -$0.73 |
| Z15 Ã- 10 (@ $0.05) | ~0.270 | ~$10.80 | $18.12 | -$7.32 |
These numbers illustrate a hard truth: at $40 ZEC, even cheap electricity barely covers costs for a single machine. Profitability improves at scale (better bulk electricity rates) and at higher ZEC prices. Use our calculator with your real electricity rate and current ZEC price before purchasing hardware.
Key Beginner Mistakes to Avoid
- Buying at retail price: New Antminers sell for $2,000–$4,000. At current profitability, payback periods are 18–36+ months. Consider used hardware.
- Ignoring electricity costs: The single biggest mistake beginners make is focusing on hashrate without calculating electricity spend.
- Using an exchange address long-term: If the exchange is hacked or freezes your account, you lose your ZEC. Use a self-custody wallet.
- Not monitoring your miner: Miners can go offline, overheat, or get throttled. Check your pool dashboard daily in the first week.
- Forgetting taxes: In most jurisdictions, mined ZEC is taxable as ordinary income at fair market value on the day received. Keep records from day one.
