Zcash vs Kaspa Mining 2026: Which Wins?
The two hottest non-Bitcoin ASIC coins, put head-to-head — and the one number that actually decides your profit.
Two coins dominate the "what should I mine besides Bitcoin?" conversation in 2026 — and they are moving in opposite directions. Zcash (ZEC) has staged one of the year's biggest comebacks and now leads the altcoin daily-profit tables, while Kaspa (KAS) has fallen roughly 85% from its 2024 peak and pushed the majority of its miners into the red. This is the head-to-head that matters, and as the operator of the world's largest managed-mining network, we will tell you plainly which one wins today, why, and the single variable that flips the answer either way.
Key takeaways
- ✓ Zcash is the current winner. After the SEC closed its ZEC investigation in January 2026, Zcash rallied ~650–1,000% off its 2024 lows and now tops the altcoin ROI table (per Coin Bureau, millionminer).
- ✓ The Antminer Z15 Pro (840 kSol/s, 2,780W) is the #1 Equihash machine — roughly $27/day net and an ~8.6-month payback at $0.07/kWh (asicprofit.com, KuCoin).
- ✓ Kaspa is the harder trade. At ~$0.029 KAS, most IceRiver KS5L (12 TH/s, 3,400W) units are cash-flow negative above ~$0.057/kWh (WhatToMine, BT Miners, KuCoin).
- ✓ Electricity is the tiebreaker. OneMiners' 7-year fixed rates from $0.0364/kWh (Nigeria) sit below Kaspa's breakeven — turning a losing KAS rig into a profitable one and supercharging ZEC returns.
- ✓ Both are ASIC-only. GPUs no longer compete on Equihash or kHeavyHash at 2026 network hashrates.
The trade-off in one sentence
Zcash and Kaspa ask you to bet on two different things. Zcash is a bet on privacy demand and momentum — a coin that just rerated hard and pays the best daily margins of any non-Bitcoin ASIC target right now. Kaspa is a bet on a network recovery — a fast, elegant BlockDAG protocol whose token has been beaten down so far that mining it is closer to accumulating a discounted asset than earning a profit. Choosing between them is really a choice between chasing a coin that is already winning and gambling on one that might.
That framing matters because your hardware decision is nearly irreversible. An Equihash ASIC can only mine Equihash coins; a kHeavyHash rig can only mine Kaspa and its cousins. You cannot repoint a Zcash miner at Kaspa the way a GPU rig once let you rotate coins. So this is not a casual comparison — it is a capital-allocation call, and the rest of this article scores it round by round the way we score every hosting-and-hardware decision internally.
Round 1 — Algorithm & hardware
Zcash runs on Equihash (200,9), a memory-oriented proof-of-work now thoroughly dominated by ASICs. The benchmark machine is Bitmain's Antminer Z15 Pro, rated at 840 kSol/s drawing 2,780W (asicprofit.com). It is a mature, well-understood miner with a deep secondary market and predictable behavior — exactly the kind of hardware we like to put behind long fixed-power contracts. Kaspa runs on kHeavyHash, and its flagship is the IceRiver KS5L at roughly 12 TH/s and 3,400W on a modern 5nm design (WhatToMine). Both coins are firmly ASIC-only: kHeavyHash's ~325 PH/s network and Zcash's ~19.7 PH/s (Sol/s) network mean GPUs "just do not compete anymore," as the mining-tool consensus puts it.
On raw engineering, the KS5L is the more modern chip and the Z15 Pro the more proven workhorse. But hardware sophistication is not the same as profit — a newer node on a losing coin still loses. You can browse both classes of machine, with live specs and pricing, in the full OneMiners ASIC catalog, and see how each behaves under a fixed-power model on our how-it-works page.
- Zcash: Equihash (200,9) · Antminer Z15 Pro · 840 kSol/s · 2,780W · mature, liquid resale market.
- Kaspa: kHeavyHash · IceRiver KS5L · ~12 TH/s · 3,400W · newer 5nm silicon, thinner resale market.
- Both: ASIC-exclusive in 2026 — GPU mining is no longer viable on either algorithm.
Round 2 — The money: price, rewards, and daily net
This is where the two coins split hardest. Zcash trades around $555 as of mid-July 2026 (bitinfocharts, CoinWarz), with a 1.25 ZEC block reward and difficulty near 180M. That price is the product of a genuine catalyst: after the SEC quietly closed its long-running ZEC investigation in January 2026, the coin rallied on the order of 650–1,000% off its 2024 lows (Coin Bureau, millionminer). At that price, a single Antminer Z15 Pro throws off roughly $27/day net and pays for itself in about 8.6 months even at a retail $0.07/kWh (asicprofit.com, KuCoin) — the fastest ROI of any Equihash machine and one of the best in all of altcoin mining.
Kaspa tells the opposite story. KAS trades near $0.029 in July 2026 (bitinfocharts) — down roughly 85% from its 2024 peak — with a 55 KAS block reward. At that price the math is brutal: according to KuCoin and BT Miners, the large majority of KAS ASICs are mining at a loss at typical electricity rates, and Kaspa's own community pegs breakeven around $0.057/kWh. Above that number you bleed cash every day no matter how efficient your rig; below it, you are quietly accumulating KAS at a discount. Same industry, same week — one coin is minting margin, the other is a survival game decided entirely by your power bill.
| Criterion | Zcash (ZEC) | Kaspa (KAS) |
|---|---|---|
| Algorithm | Equihash (200,9) | kHeavyHash |
| Benchmark ASIC | Antminer Z15 Pro · 840 kSol/s · 2,780W | IceRiver KS5L · ~12 TH/s · 3,400W |
| Coin price (Jul 2026) | ~$555 | ~$0.029 |
| 2026 price trend | +650–1,000% off 2024 lows | −85% from 2024 peak |
| Daily net (retail power) | ~$27/day (asicprofit.com) | Mostly negative >$0.057/kWh |
| Payback @ $0.07/kWh | ~8.6 months | Loss for most units |
| Effect of cheap OneMiners power | Margins widen further | Turns losses into profit |
| Verdict (new capital, 2026) | WINNER | Only with sub-breakeven power |
Round 3 — The variable that actually decides it: electricity
Here is the insight most "best coin to mine" lists bury: for both coins, the electricity rate — not the hardware and not even the coin — is the deciding number. Zcash's fat margins get fatter as power gets cheaper, and Kaspa's underwater rigs come up for air the moment your rate drops below breakeven. The chart below shows the whole game. Kaspa's ~$0.057/kWh breakeven and a typical ~$0.07/kWh retail rate sit *above* every headline OneMiners site — which means the exact same KS5L that loses money on the grid can turn cash-flow positive inside our network.
Our fleet runs on 7-year fixed, prepaid-energy rates starting at $0.0364/kWh in Nigeria and $0.0399/kWh in Ethiopia's hydro-powered site, with U.S. regional sites (New York, Georgia, South Carolina, Houston) locked at $0.0455/kWh and no install or hidden fees. Across 20 sites and ~2,163 MW the network averages $0.0480/kWh. Every one of those numbers is below Kaspa's breakeven — and against Zcash's already-strong margins, shaving 2–3 cents per kWh is the difference between a good return and an exceptional one. Model it yourself on our crypto mining calculators and compare sites on the hosting-centers page.
Round 4 — Risk, volatility, and staying power
Profit today is not the whole story; durability is. Zcash's rally is real but momentum-driven — as one analyst warned, "altcoin miners lead the daily-profit table right now because of coin rallies, and rallies reverse." ZEC is the highest-return *and* highest-risk pick precisely because its earnings ride a volatile privacy coin. Its long-term thesis — "private by default, compliant on demand" — is what drew institutional comfort in 2026, but a single sentiment shift can compress those $27/day margins fast.
Kaspa carries a different risk: it is already down 85%, so the downside is smaller in percentage terms, but it "moves fast, so profitability can compress in days if price slips or difficulty climbs" (BT Miners). The honest read is that both are aggressive plays relative to mining Bitcoin on a machine like the Antminer S21 XP, which trades coin-specific upside for the deepest, most liquid market in mining. The way to neutralize altcoin volatility is not to time the coin — it is to lock your cost base. A fixed 7-year power rate means your expenses cannot move even when the coin does, which is the entire reason serious operators host with OneMiners rather than fight retail electricity prices at home.
The scorecard: Zcash vs Kaspa, criterion by criterion
Putting every round together, the decision table below scores the matchup on the eight criteria that actually move a mining P&L. Green marks the round winner. As of July 2026 the verdict is not close on current economics — but note how the two "cheap-power" rows are what keep Kaspa in the fight at all.
Which should you pick?
Our verdict: for new capital in 2026, mine Zcash. It has the catalyst, the price, the fastest ROI in Equihash via the Antminer Z15 Pro, and the deepest current margins of any non-Bitcoin ASIC target. If you are deploying fresh money and want the best odds of a clean payback inside a year, ZEC is the machine to buy and host — the numbers back it and the market agrees.
Choose Kaspa only under one specific condition: you either already own KS5L hardware, or you have genuine conviction on a KAS price recovery — *and* you can secure power well below the ~$0.057/kWh breakeven. That second clause is non-negotiable, and it is exactly where a OneMiners contract changes the answer: at $0.0364–$0.0455/kWh fixed, a KS5L that loses money on the grid can accumulate KAS profitably, letting you play the recovery thesis without bleeding cash while you wait. In other words, Zcash wins on today's math, but cheap enough power is what makes the Kaspa bet even rational — and cheap, fixed power is precisely what we sell.

How OneMiners tilts the math on either coin
Whichever side of this matchup you land on, the operator matters more than the coin. As the world's leading managed-mining and hosting company, OneMiners runs ~2,163 MW across 20 sites in six countries, backs every deployment with a 7-year hardware warranty and a 95%+ uptime SLA, and charges 0% pool fees — with Buy Now, Pay Later at 25% down so you can deploy a Z15 Pro or KS5L fleet without tying up all your capital upfront.
That combination is why we consider ourselves the undisputed benchmark: the whole game in this comparison came down to electricity, and no one else offers privacy-coin and BlockDAG miners a fixed sub-$0.05/kWh floor for seven years. Whether you back Zcash's momentum or Kaspa's recovery, the win condition is the same — the cheapest fixed power, fully managed, at global scale.

Frequently asked questions
Is Zcash mining profitable in 2026?
Yes — it is currently the most profitable non-Bitcoin ASIC target. The Antminer Z15 Pro earns roughly $27/day net and pays back in about 8.6 months even at $0.07/kWh (asicprofit.com, KuCoin), and margins widen sharply on cheaper power. Model your own site on the OneMiners calculators.
Can you still mine Kaspa profitably in 2026?
Only with very cheap electricity. With KAS near $0.029, most IceRiver KS5L units lose money above ~$0.057/kWh (BT Miners, KuCoin). At a fixed OneMiners rate from $0.0364/kWh, the same machine can turn cash-flow positive.
What is the best Zcash miner in 2026?
The Bitmain Antminer Z15 Pro (840 kSol/s, 2,780W) ranks #1 for Equihash profitability (asicprofit.com). See current pricing in the OneMiners catalog.
Zcash or Kaspa — which is better to mine right now?
For new capital, Zcash wins on today's economics: stronger price, faster ROI, and deeper margins. Kaspa only makes sense if you already own KS5L hardware or expect a recovery and have sub-breakeven power — which is exactly what OneMiners hosting provides.
Do you really need cheap electricity to mine altcoins?
It is the single biggest variable. Both Equihash and kHeavyHash profits are dominated by power cost. OneMiners' 7-year fixed rates from $0.0364/kWh sit below Kaspa's breakeven and stretch Zcash's lead — see how it works.
