TLDR: The Complete MicroBT WhatsMiner Lineup in a Nutshell

- MicroBT has shipped ten-plus WhatsMiner generations since 2017, and the jump from the M1 (12 TH/s) to the M7D hydro units (well past 900 TH/s) is honestly wild.

- The current flagship air-cooled model is the WhatsMiner M70S, running around 13.5 J/TH. That's elite efficiency for anyone mining without hydro or immersion setups.

- Hydro and immersion tiers (M63, M66, M76S+, M79S, and the new M7D series) push past 12.5 J/TH and crack four-digit terahash numbers on single units.

- MicroBT still leans on its integrated PSU design across the lineup. That's one less failure point compared to Bitmain's external power supplies.

- Efficiency has basically tripled since the M20 era, and 2026 network difficulty (around 144 T) means older machines like the M30 series only pencil out at cheap power.

- WhatsMiner firmware support trails Antminer's third-party ecosystem, but it's gotten a lot better and now includes solid built-in tuning modes.

- A February 2026 Supreme Court ruling knocked IEEPA-based tariffs off the table, so real landed costs on Southeast Asia imports sit closer to 27-28% instead of the 47% a lot of guides still quote.

- Build quality holds up well across generations, and hashboard layouts are generally considered easier to service than some Antminer batches.

- Noise and thermal handling stay consistent across a wide ambient range, which matters if you're running a rig in a garage instead of a climate-controlled data hall.

- If you want a WhatsMiner without dealing with import logistics or noise, EndlessMining hosts M50 and M61 units at $0.08/kWh and also sells brand-new M60S+ machines outright.

- The sweet spot for most home and small-scale miners right now is the M60S or M60S+ tier, since it balances price, efficiency, and availability better than the newest M70/M73 hardware.

Bitcoin's network hashrate is sitting around 1 ZH/s this year, and difficulty has climbed past 130 T. That's a brutal environment for anyone running outdated ASIC miners. Block rewards are down to 3.125 BTC since the last halving, so every joule per terahash matters more than it did two years ago. MicroBT has been Bitmain's main rival since 2016, and the WhatsMiner lineup is the reason that rivalry keeps pushing efficiency forward year after year.

This guide walks through the complete MicroBT WhatsMiner lineup, generation by generation, so you know exactly which model fits your setup, your power rate, and your budget. We'll also cover cooling tiers, real 2026 costs, and how hosting stacks up against buying outright.

The Complete MicroBT WhatsMiner Lineup, Generation by Generation

M1 and M3 Series: Where It All Started

The M1 landed in 2017 at roughly 12 TH/s on a 16nm chip. Nothing fancy, but it proved MicroBT could actually design a chip, build a complete Bitcoin mining rig, and ship it without everything falling apart in a month. The M3 followed shortly after with slightly better thermal design and a more refined chassis. Neither model matters for 2026 mining economics, but they set the tone MicroBT still follows today: reliability first, flashy specs second.

M10 Series: The First Real Efficiency Jump

The M10 hit around 33 TH/s at roughly 65 J/TH, which nearly halved power consumption compared to the M3. That efficiency gain was huge for its time, and it introduced the dual-fan layout and modular hashboard architecture that still shows up in today's units. This generation is where serious miners started paying real attention to MicroBT as a long-term player instead of a one-off curiosity.

M20 Series: Going Head-to-Head With Bitmain

The M20S delivered about 68 TH/s at 48 J/TH using Samsung 12nm chips. It went toe-to-toe with the Antminer S17 and, in a lot of cases, ran cooler and more reliably during a period when Bitmain was dealing with quality control issues on certain S17 batches. This is the generation where WhatsMiner earned its workhorse reputation among home miners looking for a dependable ASIC.

M30 Series: MicroBT's Breakout Moment

Here's where things got serious. The M30S hit 86 TH/s at 38 J/TH, and the M30S++ pushed to 112 TH/s at 31 J/TH. Those numbers matched or beat Bitmain's S19 lineup, and MicroBT started landing big institutional mining contracts because of it. Hydro-cooled variants like the M33S+ also showed up here, marking MicroBT's first real move into liquid cooling for Bitcoin mining hardware.

M50 Series: The 5nm Leap

MicroBT jumped to Samsung 5nm silicon with the M50 series, and the M50S landed at 126-130 TH/s around 26 J/TH. That's still a respectable efficiency number, though by 2026 standards it's showing its age. At today's difficulty, the M50S mostly makes sense at rock-bottom power rates or as a dual-purpose space heater during colder months, since the heat output can genuinely offset part of your winter heating bill.

M60 Series: Pushing Past 18 J/TH

The M60S delivers 186 TH/s at 18.5 J/TH, and the M60S++ variant reaches 226 TH/s at around 16 J/TH. This generation also expanded into hydro (M63/M63S, 340-406 TH/s) and immersion (M66/M66S, 270-348 TH/s) tiers, proving MicroBT wasn't just an air-cooling company anymore. Plenty of miners still consider the M60S the best value tier in the complete MicroBT WhatsMiner lineup right now, since used prices have come down while the machine stays plenty competitive against current-gen Antminer hardware.

Noise sits around 72 dB on the standard air-cooled M60S, which is slightly quieter than a lot of comparable Antminer units. That might not sound huge on paper, but if you're running this thing in a spare bedroom or garage, every decibel counts toward keeping the household happy.

M70 and M73 Series: The Current Frontier

Announced at Bitcoin MENA in late 2025, the M70 lineup tops out at 12.5 J/TH on the immersion-cooled M76S+, with the hydro-cooled M79S blowing past 1,000 TH/s on a single unit. That's a full petahash of compute from one machine, which would've sounded like science fiction just a few generations back. The M73 series, built specifically for hydro infrastructure, leans even harder into liquid cooling for large operations that have already invested in CDU systems and containerized loops.

M7D Series: The Newest Hydro Push

MicroBT rolled out the M6DS+ and M6DS++ in March 2026, expanding the M7D family with efficiency around 15.5 J/TH and power draw near 8,600 watts. These are built for industrial farms running dense, liquid-cooled racks, not home setups. Still, they show MicroBT isn't slowing down on the innovation front, and they round out the complete MicroBT WhatsMiner lineup heading into next year and beyond.

Air-Cooled vs Hydro vs Immersion: Picking Your Cooling Tier

Air-Cooled WhatsMiners

Air-cooled models like the M60S and M70S remain the default choice for home miners and small operations. No extra infrastructure, no CDU, no immersion tank required. You plug it in, point a fan or duct at it, and go. The tradeoff is a slightly higher J/TH ceiling compared to liquid-cooled tiers, but for most hobbyist and small-commercial setups, that tradeoff is well worth the simplicity.

Hydro-Cooled WhatsMiners

Hydro units (M63, M79S, M6DS+) route coolant directly through the hashboards instead of relying on airflow. Efficiency improves noticeably, and density goes way up since you can run tighter racks without worrying about heat buildup between units. But you need a coolant distribution unit and a real facility to support it, so this tier is basically industrial-only territory.

Immersion-Cooled WhatsMiners

Immersion models (M66S, M76S+) sit fully submerged in a bath of dielectric fluid. This tier hits the best efficiency numbers in the whole lineup and also runs whisper quiet, since there's no fan noise at all. Setup cost is the catch here. You'll need tanks, fluid, and pumps before a single miner even starts hashing, so this option suits larger operations more than a garage setup.

WhatsMiner vs Antminer: How the Complete MicroBT WhatsMiner Lineup Stacks Up

MicroBT and Bitmain have traded punches for almost a decade, and 2026 is no different. Here's a quick generation-by-generation snapshot:

|---|---|---|---|

Bottom line: neither brand has a permanent lead, and honestly that competition is great news for anyone shopping for Bitcoin mining hardware. But WhatsMiner still wins on one thing Antminer can't match easily, which is the integrated PSU. One less external component means one less thing that can fail on you at 3 a.m., and it also means a cleaner, simpler setup out of the box.

Firmware, Tuning, and Software on WhatsMiner Hardware

MicroBT's stock firmware has traditionally been more locked down than Bitmain's, and that's still somewhat true in 2026. However, the gap has narrowed a lot. Every current WhatsMiner ships with built-in performance modes, usually labeled something like Low Power, Normal, and High Performance, so you can tune output without touching third-party tools. For miners who want deeper control, third-party firmware options like Vnish now support several WhatsMiner models, adding undervolting and custom pool configuration.

That said, the third-party ecosystem still isn't as deep as what Braiins OS+ offers Antminer owners. If firmware flexibility is your top priority, that's worth factoring into your decision. If you're happy running stock tuning modes and letting the machine do its thing, this gap won't affect you much at all.

Noise Levels and Thermal Management

Home miners care about noise way more than industrial operators do, and this is actually a spot where WhatsMiner tends to shine. Fan speed control and thermal curve tuning have consistently been solid across generations, and testing on models like the M60S shows stable hashrate and efficiency across a wide ambient range, from around 15°C up to 27°C, without throttling.

That consistency matters if you're running a rig in a garage, basement, or spare room instead of a purpose-built data hall. It also matters for anyone using their miner as a supplemental space heater, since predictable heat output makes it easier to plan around during cold months.

What the Complete MicroBT WhatsMiner Lineup Actually Costs You in 2026

Landed Cost and Tariffs

A lot of guides floating around still quote Southeast Asia import tariffs near 47%. That number's outdated. A February 2026 Supreme Court ruling invalidated the IEEPA-based tariffs that pushed rates that high, and real landed costs on ASIC imports now sit closer to 27-28%. That's a meaningful difference if you're budgeting a fleet purchase, so double-check any pricing guide's publish date before trusting its tariff math, since plenty of older content hasn't been updated since the ruling.

Power Cost by Model

Efficiency drives everything here. A 258 TH/s M70S at 13.5 J/TH draws about 3,483 watts. At $0.08/kWh, that's roughly $6.70 a day in electricity. Compare that to an older M50S at 26 J/TH, which burns nearly double the power for the same hashrate output, and the math gets ugly fast once difficulty keeps climbing the way it has throughout 2026.

Breakeven Reality Check

At current difficulty (around 144 T) and a 3.125 BTC block reward, older sub-30 J/TH machines mostly only make sense below $0.06/kWh or as heating units during colder months. Anything from the M60 generation forward stays profitable at more typical residential and small-commercial rates, which is exactly why that tier remains the sweet spot for most buyers browsing the complete MicroBT WhatsMiner lineup today.

Hashprice and Profitability Trends in 2026

Hashprice, meaning the dollar value of one terahash of mining power per day, has stayed under real pressure throughout 2026 as difficulty keeps grinding higher. That squeeze is exactly why efficiency has become the deciding factor between a profitable fleet and a break-even one. Miners running anything above 25 J/TH are feeling that pressure hardest right now, since the margin between revenue and electricity cost keeps shrinking with every difficulty adjustment.

This is also why the complete MicroBT WhatsMiner lineup skews so heavily toward efficiency gains generation over generation. MicroBT isn't chasing bigger machines just for bragging rights. They're chasing lower J/TH numbers because that's genuinely the only lever miners have left when hashprice compresses. If you're running a profitability calculator on any WhatsMiner model, always plug in current hashprice rather than last year's numbers, since the swings have been significant.

Used vs New WhatsMiner Hardware: What's the Better Deal?

Secondhand WhatsMiner units flood marketplaces constantly as larger operations upgrade their fleets, and that creates real opportunity for home miners. A used M60S can run noticeably cheaper than a new M70S while still delivering solid efficiency, so the math often favors buying used if you're comfortable with some wear.

The catch is warranty and remaining lifespan. A used unit that's already run 18 months at full tilt has less runway left than a fresh unit straight from MicroBT. New hardware, like EndlessMining's M60S+ listing, costs more upfront but comes with full warranty coverage and predictable performance from day one. If you're risk-averse or this is your first ASIC purchase, new hardware takes a lot of the guesswork out of the equation. If you've got repair experience or access to a service like D-Central or EndlessMining's own support, used hardware can stretch your budget a lot further.

Build Quality and Repairability Across the Lineup

WhatsMiner hardware has built a solid reputation for build quality over the years, and that reputation carries through to current generations. Hashboard layouts tend to be logical and accessible, so repair technicians can generally diagnose and fix issues without a nightmare teardown process. Common failure points across ASIC hardware in general include fan bearings, thermal paste degradation, and occasional hashboard faults after extended runtime, and WhatsMiner units aren't immune to any of that.

Still, the modular design philosophy MicroBT established back in the M10 generation has stuck around, which keeps most repairs economically worthwhile instead of forcing a full replacement. If you're planning to run a fleet for several years, that repairability factor is worth weighing just as heavily as raw efficiency numbers.

Electrical Requirements Across the Lineup

Before buying any WhatsMiner, check your electrical setup, because power draw varies a lot across the complete MicroBT WhatsMiner lineup. Older M30 and M50 units typically run fine on standard 240V circuits that plenty of home miners already have set up for other appliances. Meanwhile, the newer M60, M70, and M7D generations pull significantly more current, since higher hashrate always comes with higher wattage even as efficiency improves.

A single M70S drawing around 3,483 watts needs a dedicated circuit, and running multiple units means talking to an electrician about panel capacity before you plug anything in. This is honestly one of the most overlooked steps for first-time miners. Plenty of people buy a machine, get it home, and realize their garage outlet just can't handle the load. Also budget for proper ventilation or ducting, since these machines generate serious heat, and poor airflow will throttle performance no matter how good the miner is on paper.

If electrical upgrades sound like a hassle, that's another point in favor of hosting. A hosted M50 or M61 through EndlessMining skips the panel upgrade conversation entirely, since the facility already handles power delivery at scale.

Who Should Buy Which WhatsMiner

Home miners with moderate power rates should look at the M60S or M60S+. It's efficient enough to stay profitable, and used pricing has come down enough to make it accessible without a huge upfront investment. Miners chasing max efficiency and willing to build out hydro or immersion infrastructure should target the M70, M73, or M7D hydro tiers instead, since those numbers simply can't be matched by air-cooled hardware.

Budget-conscious miners with dirt-cheap electricity can still squeeze value out of M50-series units, especially if winter heating offsets part of the electricity bill. Industrial operations scaling fleets should be looking hard at the M7D series, since MicroBT built those specifically for dense hydro deployments and large-scale profitability. And if you're brand new to mining altogether, starting with a hosted machine removes a ton of the guesswork around cooling, noise, and electrical capacity.

Hosting and Buying WhatsMiners Through EndlessMining

Here's the thing: not everyone wants to deal with shipping, customs, noise complaints, or electrical upgrades just to run a WhatsMiner. That's exactly what hosting solves, and EndlessMining offers both hosted and new-purchase options across the complete MicroBT WhatsMiner lineup.

On the hosting side, EndlessMining currently offers the WhatsMiner M50 at 120 TH/s and 3,360W, hosted at $0.08/kWh with a straightforward monthly payment. That rate is genuinely competitive for 2026, and it takes the M50's aging efficiency and makes it viable again since you're not paying inflated residential power prices. There's also the MicroBT WhatsMiner M61 at 208 TH/s and 4,140W, also available as a monthly hosting payment. The M61 slots in as a strong mid-tier hosted option, giving you newer-generation hashrate without the upfront hassle of running your own facility.

If you'd rather own the hardware outright, EndlessMining also sells a brand-new WhatsMiner M60S+ rated at 200 TH/s and 3,400W, built for 220V-240V input and compatible with BTC, BSV, and BCH mining. That's a full-warranty, factory-fresh unit rather than a secondhand machine, which matters if you want predictable performance and don't want to gamble on wear and tear from a previous owner.

Whether hosting or buying new fits your situation better usually comes down to how much you value hands-off management versus long-term ownership. Hosting removes the operational headache entirely, and it's a great entry point if you've never run mining hardware before. Buying new gives you a hard asset you control completely, plus the flexibility to relocate or resell whenever you want.

FAQ

What's the most efficient WhatsMiner in 2026?

The immersion-cooled M76S+ leads the pack at around 12.5 J/TH. Among air-cooled models, the M70S tops out near 13.5 J/TH at 226-258 TH/s, which still counts as elite efficiency for a machine that doesn't need liquid cooling infrastructure.

Is a WhatsMiner good for home mining?

Yes, especially the M60S and newer generations. Build quality is solid, thermal management holds up well across a wide temperature range, and the integrated PSU simplifies setup compared to Antminer's external power supply design.

How does WhatsMiner compare to Antminer on reliability?

It varies by generation, but WhatsMiner has earned a strong reputation since the M20 era. Current-gen machines from both brands are mature and well-tested, so picking based on the specific model matters more than picking based on brand loyalty alone.

Are older WhatsMiner models still profitable in 2026?

Only at very cheap electricity, generally under $0.06/kWh, given current difficulty around 144 T. Machines from the M60 generation onward hold up much better at typical power rates and are a safer bet for most miners.

Can I host a WhatsMiner instead of running it myself?

Yes. EndlessMining hosts models like the M50 and M61 at competitive kWh rates, which removes the need for your own facility, cooling setup, or noise mitigation, and it's a solid option if you're just getting started.

What's the real import tariff on WhatsMiner hardware right now?

Roughly 27-28% on Southeast Asia imports as of 2026, following the February Supreme Court ruling that struck down the IEEPA-based tariffs that had pushed rates closer to 47% just months earlier.

Should I buy a hosted WhatsMiner or a new one outright?

It depends on your priorities. Hosting, like EndlessMining's M50 and M61 options, is great if you want zero setup hassle. Buying new, like the M60S+, makes more sense if you want full ownership and long-term flexibility.

How much does electricity cost affect WhatsMiner profitability?

A ton. Electricity is the single biggest recurring cost in Bitcoin mining, so even a couple cents per kWh can swing a machine from profitable to break-even. That's part of why hosted rates like $0.08/kWh matter so much, since they're often cheaper than what most people pay at home.

Where the WhatsMiner Lineup Goes From Here

MicroBT's cadence has been pretty consistent: better process nodes, higher hashrate, lower J/TH, roughly every year or so. If that pattern holds, sub-10 J/TH machines could show up within the next generation or two, likely leaning on even more advanced fabrication and further pushing liquid cooling into the mainstream. Air-cooled models probably aren't going anywhere for home miners, though, since noise, simplicity, and setup cost still matter a lot outside of industrial-scale operations.

For now, the complete MicroBT WhatsMiner lineup gives buyers a genuinely wide range of options, from budget-friendly older units to bleeding-edge hydro hardware. That range is exactly why doing your homework on specs, power costs, and hosting versus ownership pays off before you drop money on any single model.

The Bottom Line on the Complete MicroBT WhatsMiner Lineup

MicroBT hasn't slowed down, and the gap between the 2017 M1 and the 2026 M7D hydro units proves it. For most miners, the M60 generation still hits the sweet spot between price and performance, while the M70, M73, and M7D tiers exist for operations ready to go all-in on hydro or immersion cooling. And if you'd rather skip the logistics altogether, hosted options through EndlessMining let you tap into current-generation hashrate without touching a single hashboard yourself.

At the end of the day, there's no single "best" WhatsMiner for everyone. Your ideal pick depends on your power rate, your tolerance for setup work, and whether you'd rather own hardware outright or let someone else handle the operational side. Whichever route you choose, the complete MicroBT WhatsMiner lineup in 2026 gives you more genuinely solid options than it ever has before, and that competition with Bitmain is exactly what keeps pushing efficiency higher for everyone in the space.
