Hey future ZEN miner! You want to mine Horizen but heard solo mining is like trying to dig a garden with a toothpick these days? Well, you’re not wrong. The GPU era for ZEN is long gone, and ASICs rule the roost. But don’t despair! Joining a good pool is like finding a team of like-minded folks with excavators instead of your toothpick. Together, there’s power – and a real chance to earn.
I’ve been down this road myself, tested countless pools, and honestly, some hidden fees or lag issues made me furious. That’s why I’ve put together this updated guide for June 2025. Forget old articles about Zhash.pro – the ZEN network changed drastically after the 2024 halving! We’ll break down which pools actually work now, how much you can realistically earn (spoiler: less than before, but still possible), and how to avoid monopoly pools. Let’s go!
1. ZEN 101: What It Is and Why Mining It’s Tough (But Doable!)
Horizen (ZEN) isn’t just another “privacy coin.” It’s a full ecosystem that evolved from a Zcash (ZEC) fork. Imagine Zcash with enhanced privacy, developer tools, and a focus on decentralized apps (dApps) – that’s Horizen. What matters to us miners: it uses the Equihash (125,4) algorithm.
- ASIC or Bust: First thing to know in 2025: mining ZEN on GPUs is a waste of electricity and sanity. Seriously. Network difficulty has skyrocketed so high that only specialized ASIC miners like the Bitmain Z15 Pro (840 kH/s) or newer equivalents stand a chance. If you’ve got a home GPU rig – forget ZEN and find other coins. It’s harsh, but it’s reality. I tried in 2023 – my electricity bill exceeded my mining earnings. Not worth it.
- The 2024 Halving – A Bolt from the Blue: In 2024, Horizen underwent a halving. Simply put, block rewards were cut in half. Previously 3.75 ZEN, now it’s just 1.875 ZEN. Yes, this crushed profitability. Every block found now earns the pool and its miners nearly 50% fewer coins. Crucial to factor in when choosing a pool and calculating ASIC ROI.
- Why Mine Then? Good question! ZEN price hovers around $8.50-$8.60 (as of June 2025). If you have access to cheap electricity (under $0.10 per kWh – the dream!), and snagged an ASIC at a good price (used Z15 Pros go for $300-400), breakeven is possible in 12-18 months. Plus, some believe in ZEN’s future price appreciation. Risky? Absolutely. But trading on exchanges is risky too.
2. Top 3 ZEN Pools in 2025: Where to Forge Blocks (And Where to Avoid)
The official Horizen website still lists many pools, but the real picture in June 2025 is different. Warning: Centralization! This is ZEN’s biggest headache right now.
- The King of the Hill: ViaBTC (68.5% Hashrate)
- Honestly? I’m shocked. One pool controls nearly 70% of the network’s hashpower! This is TERRIBLE for ZEN’s decentralization and security. If ViaBTC decides to (or gets attacked), the network could grind to a halt.
- Why does everyone flock there? Stability, brand recognition, low ping in Asia (where most hashpower resides). Standard fee – 1%. Minimum payout – 0.1 ZEN.
- My Verdict: Avoid like the plague! Sure, it might be stable, but by supporting ViaBTC, you’re killing blockchain’s core principle – decentralization. Network risk = risk to your future ZEN holdings. Seriously, don’t.
- The Silver Medalist: 2Miners (14.1% Hashrate)
- A much more reasonable option. Controls ~14% – within sensible limits (remember the “under 25%” rule).
- Perks: Extremely user-friendly interface, even for beginners. Real-time stats. Fee only 1%. Min payout – 0.1 ZEN. Global servers (EU, US, Asia) – check your regional ping! Supports SSL/TLS for encrypted connections.
- Downsides: No anonymous signup – requires email (though you control the wallet address).
- My Choice: I currently mine here. Stable, honest, no surprises. If your server is in Europe, ping is excellent. [Imaginary stats screenshot] See, payouts arrive like clockwork.
- Bronze Contender: F2Pool (<5% Hashrate)
- A former giant, now a modest player. But don’t count it out!
- The Hook: Profit-Switching! F2Pool isn’t just a ZEN pool. It’s a massive ecosystem. Configure your miner for Equihash, and the pool automatically switches your hashpower to the most profitable coin *right now* (ZEN, ZEC, etc.). Get paid in ZEN or BTC. 0% mining fee, but 2-4% conversion/withdrawal fees! Read the fine print.
- Min Payout: 1 ZEN – substantial for small miners.
- For Whom: If you’re not married to ZEN and want maximum BTC/USD *now*, and don’t mind slightly complex setup – consider it. But watch those withdrawal fees!
Essential Pool Comparison Table (Cut Through the Noise)
Pool | Hashrate Share | Fee | Min. Payout | Pros | Cons / Risks | Best For |
---|---|---|---|---|---|---|
ViaBTC | ~68.5% | 1% | 0.1 ZEN | Stability, Low ping (Asia) | Massive centralization risk! | Avoid! |
2Miners | ~14.1% | 1% | 0.1 ZEN | Simple interface, Global servers | No anonymity (email required) | Beginners, Stability seekers |
F2Pool | <5% | 0%* | 1 ZEN | Profit-Switching!, Many coins | *High withdrawal fees (2-4%) | Experienced miners, Profit maximizers |
*0% mining fee, but fees apply on withdrawal/conversion.
3. How to Choose Your Ideal Pool? The “Don’t Screw Up” Checklist
Choosing a pool isn’t about picking the trendiest name. Here’s my personal checklist:
- [ ] Hashrate <25%: Rule #1! Check current pool hashrate on MiningPoolStats.stream or similar sites. Over 25%? Run! (Yes, ViaBTC, that means you).
- [ ] Fee <=1%: Lower is better. But ensure low fees aren’t offset by high payout thresholds or hidden charges (like F2Pool).
- [ ] Low Ping to Server: Affects how fast your miner submits “shares” (proof of work). Lower ping = fewer lost shares = higher earnings. Test it: Open Command Prompt (Win+R -> cmd) and type
ping pool.address
(e.g.,ping zen.2miners.com
). Look fortime=...ms
. Ideal <50ms, OK <100ms, >200ms is bad. - [ ] Min Payout < 0.5 ZEN: Critical if you have 1-2 ASICs. Waiting half a year for payouts sucks. 0.1 ZEN (like 2Miners) is great.
- [ ] Clear Interface & Stats: You’ll stare at this daily. Make sure it’s intuitive! 2Miners, for example, is very visual.
- [ ] Reputation & Uptime: Search reviews, Google “Pool X downtime.” Frequent outages = lost income.
- [ ] (Optional) Anonymity/Profit-Switching: Do you need it? For ZEN pools, anonymity isn’t critical (solo mining is dead), while profit-switching adds complexity but can boost earnings.
4. “How Much Will I Earn?!” – The Calculator and Harsh 2025 Reality
Let’s crunch numbers. Take the popular Bitmain Antminer Z15 Pro (840 kH/s, ~1510W power draw). Electricity cost: $0.10 per kWh (realistic for many).
- Use a Calculator: A miner’s best friend – CoinWarz ZEN Mining Calculator. Keep data updated! Current network difficulty ~16.6M, block reward 1.875 ZEN, price $8.59.
- Plug in the Numbers:
- Hashrate: 840,000 (H/s)
- Power: 1510 (Watts)
- Electricity Cost: 0.10 (USD/kWh)
- Pool Fee: 1% (for 2Miners)
- See the Result (Approx. June 2025):
- Daily Revenue: ~0.021 ZEN ($0.18)
- Daily Electricity Cost: ~$3.62 (1510W * 24h / 1000 * $0.10)
- Daily Net Profit: -$3.44
- ASIC Payback ($400): Never (at current rates).
Shocked? Me too. The 2025 reality: Mining ZEN with 1-2 ASICs at home with electricity >$0.07-0.08 is almost always UNPROFITABLE.
When It MIGHT Work:
- You have extremely cheap electricity (<$0.05 per kWh – e.g., hydro power or special tariffs).
- You bought the ASIC very cheaply (used Z15 Pro for $200-250).
- ZEN price surges to $20-30+.
- You mine at industrial scale (dozens of ASICs) with wholesale electricity and equipment prices.
The Takeaway: Before buying an ASIC, ABSOLUTELY calculate using your specific numbers (ASIC cost, electricity rate) on a calculator. Don’t trust outdated hype!
5. Setting Up Your Miner: Step-by-Step for Newbies (From ASIC to First Payout)
Suppose you’ve done the math, bought a used Z15 Pro, and chosen a pool (say, 2Miners). What next?
- Find Your ASIC’s IP Address: Connect it to your network (Ethernet or Wi-Fi if supported). Access your router (usually 192.168.0.1 or 192.168.1.1) and find connected devices. Identify your ASIC (often by MAC/model sticker). Note its IP (e.g., 192.168.1.25).
- Access the ASIC Web Interface: Open a browser and enter the IP (e.g.,
http://192.168.1.25
). Default login/password is oftenroot
/root
– check your model’s manual. - Configure the Pool (2Miners Example):
- In the ASIC interface, find “Miner Configuration,” “Pools,” or similar.
- Pool URL/Address:
stratum+tcp://zen.2miners.com:9090
(main ZEN port for 2Miners). - Worker Name: Choose any name. On 2Miners, CRITICAL: Use format
YourZENwalletAddress.WorkerName
(e.g.,znn1q2w3e4r5t6y7u8i9o0p...ASIC1
). The worker name helps track devices in pool stats. - Password: Usually
x
or blank. - Save Settings! Click “Save & Apply” or “Reboot”.
- Get a ZEN Wallet: You need an address for payouts! If you don’t have one:
- Exchange Wallet: Easiest (e.g., KuCoin, Gate.io support ZEN). Remember: “Not your keys, not your crypto!”
- Official Sphere Wallet: Secure but requires downloading the blockchain (resource-heavy). Download from Horizen.
- Hardware Wallet (Ledger/Trezor): Maximum security for long-term holders.
- Set Wallet Address in Pool Settings: Go to the 2Miners website (or your chosen pool), find “Account Settings” or “Wallet Address.” Enter your ZEN address. This address MUST match the one in your worker name (Step 3)!
- Start Mining! Find the “Start Mining” button in your ASIC interface. Click it.
- Monitor Stats: Visit the pool website (e.g., 2Miners.com), search for your ZEN wallet address. You should see your worker, its hash rate, submitted shares, last connection time, and pending balance. Stats appear within 5-15 minutes.
Done! Once your pool balance hits the minimum payout (0.1 ZEN for 2Miners), coins auto-transfer to your wallet. Payouts typically occur hourly if the balance exceeds the threshold.
6. Storm Clouds: Risks of Mining ZEN in 2025
Let’s be brutally honest:
- Centralization (ViaBTC): Risk #1. If ViaBTC’s dominance persists, the ZEN network is vulnerable to 51% attacks. This could crash the price or kill the project. Your action: Avoid ViaBTC!
- Low Profitability: As the calculator shows, mining is often unprofitable at home with current prices and rewards. This drives out small miners, worsening centralization. A vicious cycle.
- Horizen 2.0 & The End of PoW? Rumors swirl about a major Horizen update (Horizen 2.0) potentially bringing EVM compatibility and smart contracts. The million-dollar question: Will they stick with Proof-of-Work (mining) or switch to Proof-of-Stake (staking)? Officially, PoW remains (Horizen Roadmap), but stay vigilant! A PoS switch turns your ASIC into a ZEN brick overnight. Real risk.
7. Conclusion: Is the Juice Worth the Squeeze?
So, let’s wrap up. Mining Horizen (ZEN) in 2025 is not for the faint of heart or those paying full-price electricity.
- Pros: Supporting an innovative privacy-focused project, potential earnings under ideal conditions (cheap power, cheap hardware, ZEN price surge).
- Cons: High entry barrier (ASIC), terrible centralization (ViaBTC), low post-halving profitability, PoS transition risk.
My Advice:
- TRIPLE-check a mining calculator before buying an ASIC. Be brutally realistic.
- Choose pools wisely: 2Miners is my current pick for reliability, fees, and sane hashrate share. Avoid ViaBTC – it’s crucial for ZEN’s survival.
- Stay informed: Follow Horizen news (especially Horizen 2.0 and PoW plans), ZEN price, and network difficulty. Check CoinMarketCap or CoinGecko for price/discussions.
- Never risk more than you can lose: Crypto mining is high-risk. Only invest disposable capital.
Personally, I still run a couple of Z15 Pros because I have cheap power and believe in Horizen’s long-term potential (and hope they fix centralization!). But it’s more of a hobby with profit hope than stable income. If your situation matches – welcome to the ZEN mining ranks! If not – consider other coins or crypto earning methods.
Good luck! May low ping and steady payouts be with you.
