Most Profitable Altcoin to Mine in 2026?
The data says the coin barely matters — your machine and your power rate decide everything, and one "winner" is really a warning.
Here is the finding that reframes the whole "best altcoin to mine" question: in August 2026 the same three words — *altcoin ASIC mining* — produce a +$9/day profit on one machine and a −$8/day loss on another, at almost identical power draw. The coin's name is not what decides it. Your hardware efficiency and your electricity rate do. That single spread is why we lead this report with the chart, then explain it.
We are OneMiners, and we host and manage retail-accessible mining hardware across 20 sites and ~2,163 MW of contracted capacity. That vantage point lets us watch what actually earns across dozens of coins and hundreds of machines — not what a coin's community wishes were true. Below is the honest 2026 verdict on the most profitable coin to mine besides Bitcoin, and the risk that rides shotgun with every one of them.
Key takeaways
- ✓ By raw daily revenue, Zcash (ZEC) is the loudest "winner" right now — ZEC broke above $500 in mid-August 2026 (FXStreet) — but it's also the riskiest, with one firm now controlling ~18% of the network (Decrypt).
- ✓ For steady, boring profit, Litecoin + Dogecoin merge mining on an Antminer L9 is the standout: roughly +$9/day net at $0.07/kWh (BT-Miners).
- ✓ Kaspa has world-class tech but brutal miner math today — most older kHeavyHash ASICs run at a loss above ~$0.07/kWh (BT-Miners).
- ✓ Monero (XMR ~$340) stays CPU-only by design — no ASIC edge, and a real botnet/reputation risk.
- ✓ The number that actually decides profit is your electricity rate. OneMiners' 7-year fixed rates start at $0.0364/kWh (Nigeria) and average $0.0480/kWh across the network — the difference between the red bars and the green ones.
The data first: same "altcoin mining," opposite outcomes
Start with the chart, because it kills the most common myth in one glance. Three alt-algo ASICs, all drawing roughly 2.7–3.5 kW, all mining a "top altcoin" — and their daily net profit ranges from clearly green to clearly red. The variable is not the coin. It's how many joules each machine burns per unit of work, and what you pay for those joules.
The Antminer L9 merge-mining Litecoin and Dogecoin nets about +$9/day at $0.07/kWh (per BT-Miners' 2026 breakdown). A modern Antminer KS7 on Kaspa clears about +$2.94/day at the same rate. An older IceRiver KS7 (30 TH/s, 3,500 W per ASIC Miner Value) slides to roughly −$8.40/day at $0.10/kWh — it needs materially cheaper power just to break even. Notice the rate labels: the reds don't turn green by switching coins. They turn green by switching to cheaper electricity, which is the thesis of this entire report.
So "what's the most profitable coin to mine besides Bitcoin?" is the wrong question. The right one is: *which machine, at what power rate, mining which coin — and how much risk am I taking to earn it?* We'll answer coin by coin, then hand you the number that decides all of them.
Zcash: the loud winner — and the loudest warning
If you rank purely on daily revenue per machine right now, Zcash looks like the answer. ZEC pushed above $500 in mid-August 2026 (FXStreet), and OneMiners' live catalog shows an Antminer Z15 Pro (860 KH/s) listed around a $20.95/day gross figure at current prices. On a revenue basis, that is the highest-earning single altcoin ASIC we host. If the story ended there, you'd buy one today.
The story does not end there. The reason ZEC ran is also the reason we tell clients to size their position carefully: on August 18, 2026, Nasdaq-listed Cypherpunk Technologies launched what it calls the world's largest Zcash mining fleet via a $33.3M equity deal with Winklevoss Capital (The Block). That single fleet adds 4.2 GSol/s — roughly 18% of Zcash's total hashrate (Decrypt), and Zcash mining difficulty hit an all-time high of 259.69 million (FXStreet). Record difficulty means every existing miner earns fewer coins per day than it did last month, even as the price climbs.
That is the classic alt-algo trap in real time: a price spike pulls in industrial hashrate, difficulty rockets, and the per-machine reward you modeled at purchase quietly evaporates. One entity controlling ~18% of a network also concentrates governance and sell-pressure risk in a way Bitcoin simply doesn't have. Zcash can absolutely be the most profitable coin to mine this quarter — but you are buying volatility, difficulty risk, and concentration risk, not an annuity. Mine it on the cheapest power you can secure, and don't overleverage on a two-week rally. If you want to run a Zcash rig without wearing that operational risk yourself, put it on managed, low-cost power via OneMiners hosting.
Litecoin + Dogecoin: the quiet compounder
The steadiest earner in this whole field isn't the flashy one. Litecoin and Dogecoin share the Scrypt algorithm, so a single Scrypt ASIC mines both at once through merge mining — you get paid in LTC *and* DOGE for the same electricity, the same work, the same machine. That's a structural revenue advantage no single-coin altcoin offers.
On an Antminer L9 (~17 GH/s Scrypt), BT-Miners and ViaBTC both put 2026 net profit around $5–$9/day depending on rate — closer to +$9/day (~$270/month) at $0.07/kWh, thinning out above $0.10/kWh and turning negative past roughly $0.12/kWh. Break-even on the hardware lands around 18–26 months at typical rates. That's not a moonshot; it's a machine that keeps quietly clearing a margin while flashier coins whipsaw.
The trade-off is that LTC/DOGE difficulty grinds steadily upward and margins are thin, so this coin pairing punishes expensive power harder than almost anything else. It's the clearest case in the entire report where a sub-$0.05/kWh hosting rate is the difference between a compounding asset and a break-even paperweight.

Kaspa: great tech, brutal miner math right now
Kaspa deserves the engineering respect it gets — its BlockDAG design and the kHeavyHash algorithm are genuinely fast. But respect for the tech and profit for the miner are different things. KAS trades around $0.037 in August 2026, down roughly 83% from its 2024 peak, while network hashrate exploded as manufacturers dumped high-power ASICs into the market through 2023–2024. Rewards shrank; power bills didn't.
The result, per BT-Miners' 2026 ROI analysis: around 87% of Kaspa miners on the market lose money at $0.07/kWh. An older IceRiver KS7 runs deep in the red at $0.10/kWh. Only the most efficient current-gen units — an Antminer KS7-class machine at ~36 TH/s and ~2,772 W — clear a real margin (~$2.94/day net, ~19-month ROI) at $0.07/kWh. Kaspa is the sharpest illustration of the alt-algo risk this report is really about: the coin can be excellent and your machine can still bleed.
If you believe in KAS long-term, mine it only on modern, efficient hardware and only on the cheapest power you can lock in. OneMiners' newer kHeavyHash units — such as the Antminer KS5 Pro — are the ones with a fighting margin; the bargain-bin older ASICs are value traps. Match the right Kaspa hardware to a sub-$0.05/kWh rate or don't bother.
Monero: the CPU outlier (and its own kind of risk)
Monero is the odd one out, and deliberately so. XMR (~$340 in August 2026) uses RandomX, an algorithm engineered to run best on ordinary CPUs and to resist ASICs entirely. There is no efficiency arms race to win with specialized hardware — which is exactly why r/MoneroMining threads this week are about squeezing efficiency out of 6-rig CPU setups and building home dashboards, not about buying the next big box.
For a hobbyist with cheap or sunk-cost power, XMR is one of the easiest coins to *start* mining. But the economics are modest per machine, and there's a reputational and security risk that's unique to it: because RandomX runs on any CPU, Monero is the coin most abused by cryptojacking malware and botnets. Mining it legitimately is fine; just know you're entering a space where the algorithm's openness cuts both ways. This is a home-CPU play, not a hosting play — we mention it for completeness, not as a rig we'd rack for you.
The alt-algo hardware, side by side
Here's the practical hardware view. Note the pattern: efficiency (watts per unit of work) and the coin's difficulty trend matter more than the sticker price. A cheap, power-hungry ASIC on a difficulty-spiking coin is how people lose money "mining a profitable altcoin."
- Efficiency beats hashrate on the spec sheet. Two miners with the same TH/s but different wattage are not the same investment.
- Merge mining (LTC+DOGE) stacks two revenue streams onto one power bill — a structural edge.
- Single-coin ASICs (Kaspa, Zcash) carry difficulty-spike risk — a price rally invites hashrate that erodes your reward.
- Every one of these is decided at the plug. Same machine, cheaper power, opposite outcome.
The number that actually decides it: your electricity rate
Reread the chart's rate labels. The IceRiver KS7 loses $8.40/day at $0.10/kWh; drop that machine onto $0.048/kWh power and the loss shrinks toward break-even, and onto sub-$0.04/kWh it can flip green. Nothing about the coin changed — only the plug. This is why we say, bluntly, that the most profitable coin to mine is whichever one you can run on the cheapest fixed-rate power.
That's the entire OneMiners thesis, and it's why we lead capability on contracted MW rather than hype. Our headline rates are 7-year fixed and prepaid: from $0.0364/kWh in Nigeria (our cheapest active site), $0.0399/kWh at hydro-powered Ethiopia, $0.0455/kWh across U.S. regional sites like Georgia, and cold-climate Norway Arctic at $0.0448/kWh — for a network average of $0.0480/kWh across 20 sites. Every rate on that list sits well below the $0.07/kWh the profitability tables above assume, which is precisely how a thin-margin altcoin machine becomes a compounding one.
Before you buy anything, run the coin and machine through the OneMiners mining calculators at *your* real power rate — not the hopeful one on a product page. If the margin only works at $0.03/kWh and you're paying $0.14/kWh at home, the honest answer is to host it, not to run it in your garage. See how managed hosting changes the math on how it works.
The risk nobody prices into the spreadsheet
The seed of this article was the risk, so let's name it plainly. Alt-algo mining carries four risks Bitcoin mining mostly doesn't, and all four are live in the data above:
- Difficulty spikes. A price rally (Zcash today) pulls in industrial hashrate — Zcash difficulty just hit an all-time high of 259.69M (FXStreet). Your modeled reward can halve while the price is still going up.
- Price crashes. Kaspa is down ~83% from its 2024 peak. A coin can have brilliant tech and still hand miners a loss.
- Concentration. One firm now runs ~18% of Zcash's hashrate (Decrypt). Small networks can be dominated — or governed — by a single well-funded player.
- Liquidity and delisting. Smaller altcoins can get delisted or lose exchange support, stranding the coins you mined. Bitcoin's depth simply isn't there.
The mitigation isn't to avoid altcoins — it's to refuse to let any one variable sink you. Lock a fixed, low power rate so a mild price dip doesn't push you underwater. Prefer efficient, current-gen hardware over cheap old boxes. Don't bet the farm on a two-week rally. And where possible, run on managed infrastructure with a 95%+ uptime SLA and a 7-year hardware warranty, so a dead PSU on a volatile coin isn't also a week of lost revenue. That combination — cheap fixed power plus operational resilience — is the only durable edge in a game where the coin itself is the variable you can't control.
Frequently asked questions
What is the most profitable coin to mine besides Bitcoin in 2026?
It depends on your goal and power rate. By raw daily revenue, Zcash is highest right now (ZEC above $500), but it carries the most risk. For steady net profit, Litecoin + Dogecoin merge mining on an Antminer L9 is the standout (~+$9/day at $0.07/kWh). The real decider is your electricity rate — run your numbers on the OneMiners calculators.
Is Kaspa mining still profitable in 2026?
Mostly no on old hardware — BT-Miners estimates ~87% of Kaspa miners lose money at $0.07/kWh after KAS fell ~83% from its peak. Only efficient current-gen units like the Antminer KS5 Pro clear a margin, and only on cheap power.
What is Litecoin and Dogecoin merge mining?
Both use the Scrypt algorithm, so one Scrypt ASIC (like the Antminer L9) mines both at the same time and pays out in LTC and DOGE for a single electricity bill — a structural revenue edge over single-coin altcoins.
Why did Zcash mining get more competitive in 2026?
Cypherpunk Technologies launched a fleet adding ~18% of Zcash's total hashrate via a $33M Winklevoss deal (Decrypt), and difficulty hit an all-time high of 259.69M (FXStreet). More hashrate means each machine earns fewer coins per day even as the price rises.
Can I mine altcoins profitably at home?
Only if your electricity is cheap. Most 2026 alt-algo margins assume $0.07/kWh or less; typical home rates of $0.12–$0.14/kWh push many machines into a loss. Hosting on OneMiners' fixed rates from $0.0364/kWh is often the difference between profit and break-even.
