Bitmain Antminer L9 compared — Litecoin & Dogecoin Miner with 15, 16 and 17 GH/s

‍

‍

Introduction to Scrypt mining with the new Antminer L9

The Bitmain Antminer L7 is still one of the longest-lasting and economically most successful miner on the market today — even years after its release, it is still being operated profitably. In 2025, Bitmain is now bringing its successor: the new Antminer L9 series, optimized for mining of Litecoin (LTC) and Dogecoin (DOGE) based on the Scrypt algorithm.

‍

The L9 series appears in three performance levels:
15GH/s, 16GH/s, and 17GH/s — with the same design, identical software and almost identical construction.

‍

Why three variants when it's the same machine?
Because in chip production natural variances in the hashrate arise — a phenomenon known as chip binning is well known. Bitmain makes targeted use of this difference:
Instead of artificially throttling all devices, they are classified based on performance — If you want more performance, you get it for the right price.

‍

In this article, we'll show you:

• What makes the L9 series different from the L7,
• How 15, 16 and 17 GH/s compare economically,
• Which electricity costs and income are currently realistic.

‍

‍

‍

Technology overview — What is new about the Antminer L9 series?

At first glance, the L9 looks like a very powerful update to the L7 — and it is. Because: With the L9 series, Bitmain does not rely on a daring technological leap, but on targeted optimization of a proven platform.

For years, the L7 was one of the The most economically stable miner in the entire market. The combination of solid workmanship, reliable air cooling and high hashrate has made it a fixture in scrypt mining. This is exactly where the L9 picks up — with the aim of more performance with comparable efficiency and stability to deliver.

‍

‍

What has remained the same with Antminer L9?

• Design and fan setup: The L9 remains a classic 4-fan ASIC with air cooling — mechanically almost identical to the L7.
• User interface and API: It is operated as usual via Bitmain's web interface — no new training required.
• reliability: The devices run stably even under continuous load — as you would expect from the L7.

‍

‍

What has changed with Antminer L9?

• More power per device: With up to 17 GH/s, the L9 is significantly more powerful than the L7 (approx. 9.5-9.8 GH/s).
• Slight improvements in airflow: Optimized fan curves ensure minimally better heat dissipation with comparable background noise.
• Sort by performance (chip binning):
  All L9 devices are technically the same — the differences in hashrate result from natural variance in chip production.
  Instead of concealing these differences, Bitmain offers three defined models:
  • 15GH/s (standard performance)
  • 16GH/s (Balanced)
  • 17 GH/s (high end)

The advantage: operators can now targeted according to budget and electricity infrastructure decide How much power do you want to use per devicewithout having to rely on unofficial overclocking.

Overall, the L9 is a typical Bitmain product: normal design, but effective as a result. Anyone who liked the L7 will immediately find their way around the L9 — just with more output per device.

Comparing all Antminer L9 models

The Antminer L9 series is available in three variants: 15GH/s, 16GH/s and 17 GH/s. The only difference between the models lies in the Hashrate and power consumption — due to chip binning stages in production. All devices have the same technical design, use the same firmware, have identical dimensions and the same fan design. Here is the overview in detail:

‍

Antminer L9 — 15GH/s

• Processing power: 15 GH/s
• Power consumption: approx. 3,150 watts
• Energy efficiency: approx. 210 J/GH
• Noise level: approx. 72—74 dB

This is the variant with the lowest hashrate. It requires a little less power and is a bit easier to protect in the same environment — for example in stand-alone operation.

‍

💡 Important to understand:

• All models can be operated in any environment, provided that the electrical infrastructure is right.
• The choice between 15, 16 or 17 GH/s is primarily a Question of prices and electricity costs — no question of compatibility or function.
• The actual profitability results from the ratio of purchase price, hashrate and energy costs — more about this in the next section.

‍

‍

What is merged mining — and why is it crucial with L9?

A major advantage of using scrypt miners such as Antminer L9 is the option of so-called merged mining: This allows you to mine Litecoin (LTC) and Dogecoin (DOGE) at the same time — with just one device and without additional power consumption.

‍

‍

‍

‍

How does merged mining work?

• The L9 works exclusively on the Litecoin blockchain.
• Since Dogecoin uses the same algorithm (Scrypt), it can use so-called Proofs of Work Use from the Litecoin calculation.
• That is called Auxiliary Proof of Work (AuxPow).
• In practice, this means: You also get DOGEwithout having to change anything or split your hashrate.

Many mining pools (such as F2Pool or viaBTC) automatically pay out the DOGE reward together with Litecoin. You don't have to do anything — and still benefit.

‍

‍

The economic effect — what does merged mining do in practice?

Merged mining creates additional incomewithout using more power or having to manually intervene. Litecoin and Dogecoin are automatically mined at the same time — and that is exactly what gives Antminer L9 an enormous advantage over classic single-coin miners. By the way, this also increases independence, because if one coin performs worse than the other, the miner can “switch” the mined coin.

With an electricity price of 0.06 €/kWh The daily electricity costs are typically:

• roundly €4.54 at 15 GH/s model
• approximately €4.84 at 16 GH/s device
• cca €5.14 at 17 GH/s device

Currently (as of May 2025), this results Gross profits of around $28-36 per day, depending on model, pool selection and courses.

‍

‍

Historically proven — huge margins in the bull market

Shortly after its market launch, the Antminer L9 — in particular the 17 GH/s model — at the appropriate price level over 60$ income per day achieved. And that while maintaining the same power consumption.

In a bullish market environment, as was observed in 2021 or at the end of 2024 or at the beginning of 2025, the L9 significant profit margins possible — even with hosting or electricity prices of 0.20 €/kWh and more.

The combination of:

• Dual mining from LTC and DOGE
• consistently high hashrate
• and extremely high energy efficiency

makes the L9 a device that not only generates ongoing profits, but also in the bull market Performs above average.

‍

Hosting or self-operation — what's more worthwhile with Antminer L9?

The question of whether you should operate your L9 yourself or have it professionally hosted depends on several factors: electricity price, technical know-how, space availability and noise tolerance.

‍

Self-operation — useful if you have your own electricity or existing infrastructure

Self-operation is particularly worthwhile if:

• You access to cheap electricity have (e.g. through photovoltaic or special tariffs)
• one suitable space is available with ventilation (e.g. garage, cellar, outbuilding)
• She the maintenance and repair Be able to take over yourself
• They value on full control Set about operations and income

The biggest advantage: Minimal running costs. Especially with PV support, the L9 is one of the most profitable mining solutions in your own setup.

But: The noise level, heat generation and the suitable (safe) power connection for several devices often make the device impractical in a living environment. However, we can provide you with appropriate advice here.

‍

‍

Hosting — professional, convenient and predictable

If you focus on maximum stability, support and scalability, hosting offers clear advantages:

• No noise pollution or heat generation on site
• No own maintenance required — fans, paste, cleaning are done by professionals
• Stable electricity prices and professional environment
• Ideal for larger quantities, reinvestments, or international setups

Many customers also combine: Run an L9 yourself, host multiple — this allows you to gain experience and scale at the same time.

Cryptohall24 offers you:

• hosting with flexible contract terms
• Transparent prices & consumption
• Optional electricity from renewable sources

Litecoin & Dogecoin market trend — is mining worthwhile in the long term?

Many ask themselves the question: Is scrypt mining even sustainable? The answer is yes — more than ever. Especially thanks to merged mining, the broad acceptance of both coins and modern hardware such as the Antminer L9, mining Litecoin and Dogecoin is still profitable and strategically useful.

‍

‍

‍

Litecoin — stable network with planning security

Litecoin is one of the oldest cryptocurrencies in the world — decentralized, fast, cost-effective and with stable development. Particularly important for miners: The next halving is Only in 2027 instead of — until then, the current block reward of 6.25 LTC per block exist. This creates clear planning security for the coming years and enables you to reliably calculate your mining income with the L9.

‍

‍

Dogecoin — strong additional profit through merged mining

Dogecoin is based on the same proof-of-work mechanism as Litecoin — that's why both coins can Parallel mined without the need for additional electricity.

The so-called Merged mining enables:

• additional income in DOGE,
• without additional technical costs,
• with full automation via common pools such as F2Pool, viaBTC or Antpool.

As a result, the total return per kilowatt hour is significantly improved — and that is a real competitive advantage for miners with modern equipment.

‍

‍

Why the Scrypt network is here to stay

Unlike many smaller altcoins, the Scrypt network — consisting of Litecoin, Dogecoin and a few other tokens — has been tried and tested for over ten years.
The reasons:

• Broad user base and infrastructure
• Integration with wallets, stock exchanges and payment systems
• Relatively stable difficulty despite growing hashrate
• Proven decentralization without major scaling problems

Through the combination of technical maturity, Merged mining and one predictable reward system until at least 2027 Scrypt mining is one of the most stable and least speculative mining models in the crypto sector.

‍

‍

Our conclusion about scrypt mining

With an Antminer L9, you get:

• Two sources of income (LTC + DOGE),
• stable block rewards until at least 2027,
• and a mining infrastructure that has been tried and tested over the long term.

Whether in-house or in hosting:
Scrypt mining remains economical — if you use the right hardware.

Bitmain Antminer L9 FAQ

‍

What are the technical variants of the L9?

The Antminer L9 is available in three versions: with 15, 16 or 17 GH/s.
The devices are structurally identical — the difference lies exclusively in computing power and power consumption. Bitmain sorts chips by efficiency (“chip binning”):

• The 15 GH/s version consumes approx. 3,150 watts
• The 16 GH/s version approx. 3,360 watts
• The 17 GH/s version approx. 3,570 watts

All models use air cooling, weigh approx. 13.5 kg and are around 370 mm long.

‍

‍

What is the difference between the L9 and the L7?

The L7 was the reference model for scrypt mining for a long time — with 9.16 GH/s and around 3,425 watts of power consumption.
The L9, on the other hand, brings:

• upto almost twice as much hashrate,
• chez equal or even slightly lower consumption,
• and one significantly better energy efficiency (around 0.21 J/MH compared to 0.37 J/MH for L7).

In addition, the L9 is quieter in cool environments, as the fan controller is more modern.
Anyone who is new to or upgrade will definitely get the more economical solution with the L9.

‍

‍

Is the L9 loud? Can I run it at home?

The L9 works with four temperature-controlled fans. In cool environments, it runs significantly quieter than many other miners, including the L7. Approx. 72—76 dB are typical.

Operation in living rooms is not recommended — but the L9 is easy to use in ventilated cellars, outbuildings or containers. A sound insulation box can also significantly reduce the volume.

‍

‍

Which power protection do I need?

For safe continuous operation, one is sufficient C32 fuse at 230 V.
This is common in many workshops, outbuildings or on farms.
It is important to note that the cable length and cable cross-section should match the performance and environment — in case of doubt, have it checked by an electrician.

‍

‍

Can I operate the L9 with photovoltaics?

Yes — the L9 is very suitable for PV power, especially when used by yourself or with battery storage.
A single miner consumes around 3.2 to 3.6 kWh per hour. With 8 hours of sunshine a day, this means that around 25 to 30 kWp of PV output would be required for a complete supply.

Many users combine solar with grid power — low self-consumption during the day, stable grid connection at night (direct stock exchange because cheaper) or battery operation. This makes mining particularly efficient.

‍

‍

How much maintenance does the L9 require?

• Remove dust from fans and cooling fins regularly
• Replace the thermal paste approximately once a year to ensure optimal heat transfer
• Clean the device externally and check for corrosion or deposits
• Check that all connectors are securely seated

Maintenance is easy and can also be carried out yourself if required — especially for individual use or small setups.

‍

‍

What does “merged mining” mean in Litecoin and Dogecoin?

The Antminer L9 computes on the Scrypt algorithm — and therefore simultaneously for two blockchains: Litecoin and Dogecoin.

The principle is called Merged mining: Both coins share the same proof of work, which allows you to:

• Earn two coins at the same time,
• without double power consumption,
• and without any additional devices or configuration.

Many pools such as F2Pool or viaBTC automatically pay out DOGE and LTC at the same time.

‍

‍

How profitable is the L9 right now?

As of May 2025, depending on the model, the gross return is around:

• $28-$30 per day with the 15 GH/s model
• $30 - $33 with the 16 GH/s model
• $33 — $36 with the 17 GH/s model

Electricity costs of 0.06 €/kWh are around 4.50 to 5.20€ per day — depending on the model.
Tip: The L9 was already in the bull market Over 60$ daily profit possible. This significantly reduces amortization.
