Maria Reyes lives in Sacramento and pays PG&E roughly $0.13 per kilowatt-hour after delivery and tier charges. Last December she bought an Antminer S21 Pro thinking she would home-mine Bitcoin out of her garage. Hashrate looked great. The dashboard updated every few seconds. Four months in, her actual operating math came in at a net loss of $640 across the period. Power cost outran mining revenue by enough that the machine was financially worse than turning it off.
She switched to an Antminer L9 in February. Same garage, same wall outlet, same $0.13/kWh. The L9 is a Scrypt-algorithm ASIC built for Litecoin and Dogecoin merged mining, the kind of machine most Bitcoin-focused miners ignore as a sideshow. The honest result so far: she is still mining at a loss in absolute terms, the L9 just loses less than the S21 Pro did, and her path to profitability now depends on a Dogecoin price move rather than a Bitcoin halving cycle.
That is not a triumphant pivot story. It is the actual story home miners need to hear. At residential power rates above $0.10/kWh, no Bitcoin SHA-256 hardware on the market produces positive daily margin at current hashprice. The L9 produces less negative margin in some scenarios, and it gives the operator exposure to two different price assets (LTC and DOGE) instead of one (BTC), which changes the upside calculation. That is the whole pitch. Anyone telling you home Scrypt mining is unambiguously profitable in 2026 is selling something.
What follows is the honest version of what merged mining is, how it actually works at the AuxPoW protocol level, what the Antminer L9 produces in real revenue at three different electricity rates, and the specific conditions under which a home miner should actually buy one. The piece does not assume Bitcoin is the only game in town. It also does not pretend Scrypt mining is a guaranteed escape from residential power constraints. It is a different bet with different upside and different break-even mechanics.
If you have already worked through whether Bitcoin home mining makes sense at your power rate, our home mining versus hosted mining breakdown covers the SHA-256 economics in detail. This piece picks up where that one leaves off, for the cohort of home miners who have looked at Bitcoin mining math and walked away.
What merged mining is, and why it works without splitting your hashrate
Merged mining is the practice of using one mining machine to secure two different blockchains at the same time, earning rewards from both. The technical mechanism is called Auxiliary Proof of Work, or AuxPoW. Per Tari Labs’ documentation, "merged mining is the act of using work done on another blockchain (the Parent) on one or more than one Auxiliary blockchain and to accept it as valid on its own chain, using Auxiliary Proof-of-Work (AuxPoW), which is the relationship between two blockchains for one to trust the other’s work as their own."
The condition that makes merged mining possible: both blockchains must use the same hashing algorithm. Litecoin and Dogecoin both use Scrypt. Bitcoin and Namecoin both use SHA-256. A miner running Scrypt hardware can secure LTC and DOGE simultaneously. A miner running SHA-256 hardware can secure BTC and Namecoin simultaneously. The hash work itself does not change. What changes is whether the result gets validated against one chain or both.

A miner running Scrypt hardware can secure LTC and DOGE simultaneously. A miner running SHA-256 hardware can secure BTC and Namecoin simultaneously. The hash work itself does not change. What changes is whether the result gets validated against one chain or both.
The miner finds the same Scrypt hash they would have found mining Litecoin alone. The pool software wraps that hash with an AuxPoW header that lets the Dogecoin chain validate it independently. Per OKX’s explanation, "every time you discover a valid block for Litecoin, that solution can also be checked for validity on Dogecoin. Coins that support merge mining include Dogecoin, Litecoin, Namecoin, and several other Scrypt-based coins."
The critical detail that confuses most newcomers: there is no efficiency loss. The miner is not splitting hashrate between two chains. The same computational work that produces a Litecoin hash gets reused on Dogecoin. Per the BT-Miners L9 analysis from January 2026, "Antminer L9 fully utilizes the Auxiliary Proof-of-Work (AuxPoW) protocol, enabling miners to compute hashes for multiple Scrypt-based blockchains simultaneously, without reducing hashrate allocated to the primary chain (Litecoin)."
From the operator’s perspective the experience is simple. Point your L9 at a merged-mining pool (Litecoinpool, F2Pool, ViaBTC, Antpool). Set your Litecoin payout address. Set your Dogecoin payout address. The pool sends both rewards to the respective addresses based on your contributed hashpower. You do not configure two separate miners or run two separate pool connections. The protocol handles the dual validation invisibly.
How LTC and DOGE became the most successful merged mining pair
Dogecoin launched in December 2013 as a fork of Lucky Coin, which was itself a fork of Litecoin. The three projects shared the same Scrypt algorithm, which created a problem for Dogecoin specifically: Litecoin had more mining hashrate, which meant Litecoin’s network was more secure. Dogecoin’s smaller hashrate made it vulnerable to 51 percent attacks. Per Litecoin.com’s historical write-up, "Of the options discussed, Proof-of-Stake (PoS), Auxiliary Proof-of-Work (AuxPoW, or ‘Merged Mining’) or switching to a completely different mining algorithm were the main choices. Throughout this phase, Litecoin founder Charlie Lee contributed to the discussion by explaining to the Dogecoin community the benefits and negatives of merged mining with Litecoin."
Dogecoin hardforked to enable AuxPoW on August 28, 2014, at block 371,337. Per Litecoinpool’s announcement at the time, "Starting today, Dogecoin can be mined alongside Litecoin, by using a technique known as merged mining (or ‘AuxPoW’, which stands for ‘auxiliary proof of work’) that allows multiple cryptocurrencies to be mined at the same time."
The market response was immediate. Per Binance Research’s case study, "Within one month, Dogecoin’s hashrate/mining difficulty increased by +1500% as large mining pools widened their operations. Since then, Dogecoin’s hashrate has exhibited an extremely strong and positive correlation (0.95) with Litecoin’s hashrate." Litecoin miners had no reason not to also mine Dogecoin once it cost them nothing extra. Within weeks, the majority of Dogecoin blocks were being produced through merged mining rather than standalone Dogecoin mining.
Charlie Lee himself addressed the Dogecoin community on Reddit during the merged mining transition with a quote that has aged well as a framing for Dogecoin’s long-term economics. He compared Dogecoin’s rapid early issuance to a startup that paid out most of its equity in year one: "Using the startup analogy, imagine if Coinbase paid 95% of its equity to its employees hired in its first year, how can it hire good people after its first year? Is it still possible to succeed? Yes, but it will be really, really hard."
The point Lee was making: Dogecoin’s monetary policy front-loaded coin distribution heavily, which would create downward pressure on price unless something else carried the security model. Merged mining was that something else. By piggybacking on Litecoin’s hashrate through AuxPoW, Dogecoin solved its security problem without needing to compete for miners on its own merits.
Today, per OKX’s tracking, "over 70% of Dogecoin’s hashpower comes from merge mining." Some sources cite even higher numbers approaching 90 percent. The Litecoin-Dogecoin merged mining relationship is not just historically significant; it is structurally inseparable. You cannot meaningfully mine Dogecoin alone in 2026, and almost no one tries.
The Antminer L9: current Scrypt flagship
The Antminer L9 launched in May 2024 on a 6nm chip process. Per Simple Mining’s April 2026 review, "The L9 delivers 15 to 17 GH/s at roughly 0.21 J/MH, making it Bitmain’s most efficient Litecoin and Dogecoin miner." It replaced the L7 (which had been the Scrypt workhorse since 2021) and currently sits at the top of the in-production Scrypt ASIC stack.
Spec-by-spec breakdown: Hashrate: 15 to 17 GH/s depending on variant. The L9, L9 Pro, and L9 Hyd run different bins. Real-world hashrate variance runs roughly ±3% from rated.
Efficiency: Approximately 0.21 J/MH (joules per megahash). For context, the L7 ran at roughly 0.36 J/MH. The L9 is 42 percent more efficient than its predecessor at the same algorithm.
Power draw: 3,150 to 3,400W operating wall draw. Dual C20 power inputs (two power cords required, not one) handle the load.
Algorithm: Scrypt only. The L9 cannot mine Bitcoin (SHA-256) or Kaspa (kHeavyHash) or Monero (RandomX). It is a single-purpose Scrypt machine.
Noise: Bitmain rates the L9 at 75 dB. Per Simple Mining’s testing, "under load with four fans at RPM, the unit runs closer to 80 dB in practice. That is lawnmower territory and eliminates residential deployment for almost everyone."
Heat output: Approximately 3,000W of heat dissipation. Requires real ventilation and ambient intake under 45°C.
Form factor: Standard Antminer chassis size. Drops into existing rack infrastructure designed for S19 or S21 series miners.
Compared to the outgoing L7 (9.5 GH/s at 3,425W, ~0.36 J/MH), per Simple Mining’s analysis, "The L9 produces roughly 79 percent more hashrate than the L7 from the same slot and circuit, at 42 percent better efficiency. If you’re on L7s with power under $0.08/kWh, the upgrade math is clear. Above $0.10/kWh, the L9 still usually pencils because it stays profitable at difficulty levels where the L7 does not."
That last sentence is the upgrade thesis for existing L7 operators. The L9 extends the profitability ceiling at higher power costs because the efficiency gain (42 percent) outpaces typical Scrypt difficulty growth. An L7 operator at $0.10/kWh who is currently mining at break-even can move to an L9 at the same power cost and capture meaningful margin without changing their facility.
The Doge subsidy effect: 60 percent of L9 daily revenue comes from DOGE, not LTC
This is the section most Scrypt mining content gets wrong. The default mental model is that you mine Litecoin and receive Dogecoin as a footnote bonus. Pull up the actual numbers and that mental model flips.

The Doge subsidy effect: 60 percent of L9 daily revenue comes from DOGE, not LTC
This is the section most Scrypt mining content gets wrong. The default mental model is that you mine Litecoin and receive Dogecoin as a footnote bonus. Pull up the actual numbers and that mental model flips.
At current prices (LTC $54.55, DOGE approximately $0.20) and current Scrypt difficulty (91.99M per CoinWarz), an L9 running at 17 GH/s 24/7 generates approximately $3.40 in daily gross revenue. The split: $1.36 from Litecoin block rewards, $2.04 from Dogecoin merged mining rewards. Dogecoin contributes 60 percent of daily revenue.
The math behind that split is structural. Litecoin produces 6.25 LTC per block (post-August 2023 halving) at roughly 2.5-minute block times. Dogecoin produces 10,000 DOGE per block at roughly 1-minute block times, with no halvings (per Dogecoin’s monetary policy, fixed issuance of approximately 5 billion new DOGE per year forever). The much larger absolute DOGE issuance, multiplied by current DOGE price, lands roughly half again as much daily revenue as the LTC side.
The implication for operators is meaningful. Per cryptonewsnavigator’s analysis, "Scrypt ASIC operators usually get an extra 5-8% in income from merge mining, but what they actually earn depends on their hardware." That 5-8% figure understates current reality. At today’s LTC and DOGE prices, the merged mining contribution is closer to 150 percent of standalone LTC mining revenue, not 5-8 percent on top.
THE DOGE SUBSIDY IS THE OPTION CONTRACT When Dogecoin trades at $0.20 (current), an L9 generates roughly $3.40/day gross. When Dogecoin trades at $0.30 (a 50% move that has happened multiple times in the past 24 months), the same machine generates approximately $4.40/day. When Dogecoin trades at $0.10, the same machine drops to $2.40/day. Bitcoin SHA-256 hardware has no equivalent secondary asset exposure. That asymmetric upside is what makes the L9 a different kind of bet.
Real profitability at three electricity rates
Here is what the numbers actually look like at three different power costs. All scenarios assume a single L9 at 17 GH/s, 3,400W wall draw, 24/7 operation, current LTC and DOGE prices, and current Scrypt difficulty.

Real profitability at three electricity rates
Here is what the numbers actually look like at three different power costs. All scenarios assume a single L9 at 17 GH/s, 3,400W wall draw, 24/7 operation, current LTC and DOGE prices, and current Scrypt difficulty.
Residential power: $0.13/kWh (PG&E Sacramento, similar US metros)
Daily revenue: $3.40. Daily power cost: 3.4 kW × 24 hours × $0.13 = $10.61. Daily net: minus $7.21. Annualized: minus $2,632.
At residential rates above $0.10/kWh, the L9 mines at a hard loss. The economics do not work at any LTC or DOGE price within a normal trading range. For DOGE alone to push this scenario into break-even, DOGE would need to roughly triple to approximately $0.60. That is possible but not a base case to plan around.
Hosted at scale: $0.075/kWh (MillionMiner Tier 3, 10+ unit deployment) Daily revenue: $3.40. Daily power cost: 3.4 kW × 24 hours × $0.075 = $6.12. Daily net: minus $2.72. Annualized: minus $993.
Even at hosted Tier 3 pricing, the L9 still loses on raw daily power math at current LTC and DOGE prices. The honest read here is that current Scrypt difficulty (91.99M, near record highs per CoinWarz, with a hashrate of 2.32 PH/s as of April 25 2026) combined with depressed LTC and DOGE prices has compressed margins across the entire Scrypt mining ecosystem. The L9 is not exempt.
Where the math flips at this rate: when DOGE moves higher. At DOGE $0.30 (a 50 percent move from current), the daily revenue rises to roughly $4.40, which produces a daily profit of approximately $1.04 net of $0.075 power. At DOGE $0.40, daily profit climbs toward $2.30. The Tier 3 hosted L9 is not a profit machine at current conditions; it is a profit machine in the conditional case where DOGE recovers toward its prior trading range.
Enterprise / industrial power: $0.05/kWh
Daily revenue: $3.40. Daily power cost: 3.4 kW × 24 hours × $0.05 = $4.08. Daily net: minus $0.68. Annualized: minus $248.
At sub-$0.06 industrial power, the L9 sits near break-even at current prices. Drop the power rate to $0.04 (achievable at hydro-backed industrial sites) and the same machine produces roughly $0.42/day net at current conditions. Layer in any DOGE price recovery and the profile improves rapidly.
Per the Simple Mining review: "At $0.08/kWh a 17 GH/s L9 nets roughly $2.71 per day, or about $81 per month at current hashprice. Drop the power rate to $0.07/kWh and net profit climbs to roughly $3.50 per day." Their numbers and ours diverge slightly because Simple Mining used different LTC and DOGE price snapshots; the directional conclusion is the same. Power cost is the dominant variable. The L9 rewards cheap power.
The honest framing: who should actually buy an L9
Three operator profiles where the L9 makes sense in 2026:
Profile 1: Existing L7 operator at $0.07-$0.10/kWh hosted
If you already operate L7s on a hosted contract at $0.07-$0.10/kWh and your L7s are running thin or break-even, the L9 upgrade math justifies itself on efficiency alone. The 42 percent efficiency improvement at the same power cost translates to meaningful profit at conditions where the L7 produces nothing. An L7 operator paying $0.08/kWh on 10 machines, currently breaking even, can move to 10 L9s and produce roughly $27/day net profit at current conditions, or roughly $9,800/year on the same fleet footprint.
Profile 2: Operator with sub-$0.06/kWh industrial power
If you have access to industrial power below $0.06/kWh (whether through a dedicated facility, a sovereign-backed allocation, or a private utility contract), the L9 is currently the most efficient way to convert that power into Scrypt revenue. The asymmetric DOGE upside makes the position more attractive than equivalent SHA-256 deployment at the same rate, particularly given Bitcoin’s halving cycle compresses SHA-256 economics every four years while Dogecoin’s issuance is constant.
Profile 3: Operator with conviction on DOGE
If you have a directional view that Dogecoin is undervalued at current prices and likely to recover, the L9 is the cleanest way to express that view through hashrate ownership. The math: at $0.075/kWh hosted, every $0.10 move in DOGE adds approximately $1.00/day per machine in profit. Over a 12-month period, a 50 cent DOGE recovery on a 10-machine fleet produces roughly $18,250 in additional revenue beyond current-conditions modeling. That is the option contract framing: the L9 captures upside on DOGE without requiring the operator to time entry, exit, or correlate with broader crypto market moves.
Three profiles where the L9 does not make sense:
1. Home miners at residential rates above $0.10/kWh. The math does not work, and no realistic LTC or DOGE price recovery rescues it. Migrate to hosted or do not deploy.
2. First-time miners with no existing infrastructure. The L9’s 80 dB noise, 3,000W heat dissipation, and dual-C20 power requirement make it an industrial machine, not a starter unit. Begin with hosted deployment of any flagship miner before considering a home L9 or any other retail-scale Scrypt operation.
3. Operators looking for diversification without a thesis. The L9 is a focused bet on Scrypt-pair price action plus your power cost basis. If you are buying it because someone told you "merged mining doubles your revenue," reread the math sections above. Merged mining does not double your revenue; it adds a secondary asset to your revenue mix that is structurally tied to the primary asset’s hashrate.
The Bells and Pepecoin bonus: multi-chain merged mining
The Litecoin-Dogecoin pair is the dominant Scrypt merged mining pairing, but it is not the only one. Per the BT-Miners L9 analysis, "Antminer L9 primarily mines Litecoin (LTC) and Dogecoin (DOGE), while supporting merged mining for other Scrypt-based PoW coins such as BEL (Bells) and PEP (Pepecoin) through AuxPoW-compatible pools."
Bells (BEL) and Pepecoin (PEP) are smaller Scrypt-based proof-of-work chains that have implemented AuxPoW to piggyback on Litecoin’s mining infrastructure. The same way Dogecoin used Litecoin to bootstrap its security in 2014, these newer chains are using Litecoin in 2025-2026. Some merged mining pools support adding BEL and PEP rewards on top of standard LTC + DOGE earnings.
Honest framing: the additional revenue from BEL and PEP merged mining is small in absolute terms (typically 1-3 percent of total daily revenue) but it represents free upside if you select a multi-chain merged mining pool. The chains are highly speculative on price and may not exist in their current form 12 months from now. Treat them as lottery tickets that come bundled with your base LTC/DOGE operation.
For most operators, the simpler path is to stick with a Litecoinpool or F2Pool merged mining setup that handles LTC + DOGE cleanly and ignore the smaller chain optionality. Operators with conviction on emerging Scrypt chains can configure pool support for BEL and PEP through specialized providers, accepting the operational complexity in exchange for the marginal additional exposure.
Hosted L9 versus home L9: the practical decision
The L9’s noise profile (80 dB under load), heat output (~3,000W), and electrical requirements (dual-C20, requires two dedicated 240V circuits or one industrial circuit) eliminate residential deployment for almost everyone. The exceptions are operators with detached outbuildings, garages with dedicated electrical service, or rural locations with industrial-grade power available.
For everyone else, hosted deployment is the realistic path. Our hosting cost breakdown covers the four-tier MillionMiner pricing structure. The relevant tiers for L9 deployment: 1. Tier 2 (5-9 units): $0.075/kWh + $5/month standing fee per unit. Effective rate at 6 L9s: roughly $0.0768/kWh. 2. Tier 3 (10+ units): $0.075/kWh, no standing fee. The same rate as Tier 2 base but without the per-unit monthly fee. 3. Enterprise (50+ units): Negotiated below the public Tier 3 rate. For larger Scrypt operators, this is the relevant pricing band.
Hosted deployment also handles the noise problem (industrial facility, no residential proximity), the heat problem (engineered cooling), the electrical problem (three-phase industrial supply), and the repair problem (12-month warranty included in the hosting tier). For an operator running 5+ L9s, hosted is the obvious choice on operational grounds alone, even before the power cost differential against residential rates.
For operators with sub-$0.06/kWh power available privately (rare in retail; common at industrial scale), self-hosting can produce better unit economics than third-party hosting. The math depends on facility costs amortized across the fleet. At 50+ L9s with private $0.05/kWh power, self-hosting typically beats Tier 3 hosting on direct economics; below 20 units, the operational overhead usually pushes self-hosting net-negative versus third-party hosting at $0.075.
Frequently asked questions
Can you really mine Litecoin and Dogecoin at the same time?
Yes. The mechanism is called Auxiliary Proof of Work (AuxPoW), introduced to Dogecoin in August 2014. A Scrypt ASIC like the Antminer L9 produces a hash that satisfies Litecoin's difficulty target. The same hash, packaged with a small AuxPoW header, can simultaneously satisfy Dogecoin's difficulty target. You earn LTC and DOGE rewards from one machine, with no efficiency loss on either chain. This works because both networks use the same Scrypt hashing algorithm.
Does merged mining reduce my Litecoin earnings?
No. Merged mining does not split your hashrate. The same computational work that produces a Litecoin hash gets reused on Dogecoin. Your Litecoin block-finding probability is identical whether you mine LTC alone or LTC + DOGE merged. The Dogecoin rewards are pure additional revenue with no offsetting cost in either electricity or hashrate. This is the structural feature that makes AuxPoW different from "profit-switching" pool strategies that move hashrate between chains.
What is AuxPoW in simple terms?
AuxPoW (Auxiliary Proof of Work) is a protocol that lets one blockchain (the auxiliary chain, like Dogecoin) accept proof-of-work performed on another blockchain (the parent chain, like Litecoin) as valid for its own block production. The auxiliary chain checks a small header attached to the parent chain's mining solution. If the math validates, the auxiliary chain accepts the block as found. Per Tari Labs technical documentation, "the Parent blockchain does not need to be aware of the AuxPoW logic, as blocks submitted to it are still valid blocks." This is how one machine secures two chains.
How much can I earn mining LTC and DOGE on an Antminer L9?
At current LTC ($54.55) and DOGE (~$0.20) prices with Scrypt difficulty at 91.99M, a 17 GH/s L9 generates approximately $3.40 per day in gross revenue, split roughly $1.36 from Litecoin and $2.04 from Dogecoin. Net profit depends on your power cost. At $0.05/kWh you sit near break-even. At $0.075/kWh hosted you operate at a small daily loss in current conditions. At $0.13/kWh residential you lose roughly $7.21 per day. The L9 economics are dominated by power cost, with secondary exposure to DOGE price moves.
Is the Antminer L9 profitable at residential electricity rates?
Generally no. At residential rates above $0.10/kWh, the L9 mines at a daily loss at current LTC and DOGE prices. For the L9 to produce break-even or profitable economics at $0.13/kWh residential, DOGE would need to roughly triple from current levels to approximately $0.60. That is possible but not a planning base case. Home miners at residential rates should migrate to hosted deployment or not deploy. The exception: operators with sub-$0.10/kWh residential rates available through specific utility programs or rural cooperative arrangements.
Should I buy an L9 or upgrade from an L7?
If you already operate L7s on hosted power at $0.07-$0.10/kWh, the L9 upgrade math justifies itself. The L9 produces 79 percent more hashrate at 42 percent better efficiency. Per Simple Mining, "Above $0.10/kWh, the L9 still usually pencils because it stays profitable at difficulty levels where the L7 does not." For an L7 operator currently breaking even, moving to L9s at the same power cost typically produces meaningful profit. For first-time Scrypt buyers, skip the L7 entirely and buy directly into L9 hardware.
Can I mine Bells and Pepecoin on the L9 too?
Yes, through AuxPoW-compatible pools that support multi-chain merged mining. Bells (BEL) and Pepecoin (PEP) are smaller Scrypt-based chains that adopted AuxPoW following the Litecoin-Dogecoin model. Some merged mining pools add BEL and PEP rewards on top of base LTC + DOGE earnings. The additional revenue is typically 1-3 percent of total daily revenue. Treat it as bundled lottery upside rather than a primary income stream. Most operators stick with standard LTC + DOGE pools (Litecoinpool, F2Pool, ViaBTC) and do not configure smaller-chain support.
Which mining pool is best for LTC + DOGE merged mining?
For most operators, Litecoinpool, F2Pool, or ViaBTC are the standard choices. Litecoinpool was the original merged mining pool (their announcement in September 2014 marked the launch of the LTC + DOGE pairing) and remains a transparent low-fee option. F2Pool offers broader payout options and merged mining support across multiple Scrypt chains. ViaBTC has competitive fee structures and good DOGE liquidity. Antpool also supports LTC + DOGE merged mining. Pool selection matters less than confirming the pool supports DOGE merged mining (most do) and that you have configured both LTC and DOGE payout addresses.
Why does Dogecoin have no supply cap and how does that affect mining?
Dogecoin's monetary policy fixes new issuance at 10,000 DOGE per block forever, with no halving cycles. That produces approximately 5 billion new DOGE per year permanently. Per Charlie Lee's 2014 Reddit AMA: "Using the startup analogy, imagine if Coinbase paid 95% of its equity to its employees hired in its first year, how can it hire good people after its first year?" The implication for miners: DOGE rewards do not compress over time the way Bitcoin block subsidies do. The trade-off: continuous issuance creates structural downward pressure on DOGE price in the absence of demand growth. Mining DOGE is a bet that demand grows faster than supply.
Should I host my L9 or run it at home?
For most operators, host. The L9 produces 80 dB of noise (lawnmower territory), dissipates roughly 3,000W of heat, requires dual-C20 power inputs (two dedicated circuits), and runs 24/7. Residential deployment requires a detached outbuilding or industrial-grade garage, and even then the noise typically violates municipal ordinances. Hosted deployment also produces better unit economics at retail scale because the hosting rate (around $0.075/kWh at MillionMiner Tier 3) beats most residential rates. The exception is operators with sub-$0.06/kWh power available privately and 50+ unit fleet scale, where self-hosting can pencil. For 1-10 unit operators, hosted is almost always the right choice.
The bigger picture
Maria moved her L9 to MillionMiner’s Missouri Facility A in March, settling into Tier 2 hosted pricing at $0.075/kWh + $5/month standing fee. Her March operating math came in at a daily loss of approximately $2.72, just like the model. April improved slightly because DOGE traded modestly higher; her current run-rate is closer to a $1.50 daily loss per machine. She is not making money on the L9 today. She is paying roughly $50 per month to hold a position that captures upside if Dogecoin recovers, hedged against further LTC and DOGE downside by the operational efficiency of hosted infrastructure.
That is a more honest framing than "the L9 is profitable where the S21 Pro is not." Both machines lose money for residential miners at current prices. Both machines win at sub-$0.06/kWh power. The differences are in the secondary asset exposure (DOGE for the L9, nothing for the S21 Pro) and the upgrade economics from prior-generation hardware (L9 vs L7 is straightforward; S21 Pro vs S19 series depends heavily on remaining warranty and operational track record). Pick the bet that matches your power cost basis and your conviction on the underlying assets.
For operators evaluating Scrypt deployment, the practical first step is verifying your true delivered power cost (not the marketing rate on your utility bill, but the all-in cost including delivery fees, demand charges, and seasonal tiers). At a verified power cost above $0.10/kWh, do not deploy the L9 at home. At $0.07-$0.10/kWh hosted, the L9 makes sense as a Scrypt position with DOGE upside. At sub-$0.06/kWh industrial, it is a structurally strong deployment that competes favorably against equivalent SHA-256 hardware.
If you want to see the L9 inventory we currently have available, the Dogecoin and Litecoin miners shop page has live stock and current pricing. For hosting questions specific to L9 deployment (cooling configuration, noise containment, three-phase requirements at scale), the hosting team handles these conversations directly through the contact page. The 24-hour free trial activates within a day if you want to verify the hosting infrastructure on a single L9 before committing to a fleet deployment.
The piece title called Scrypt merged mining "the only way most home miners should mine right now." The honest revision: it is the only path with positive expected value for operators who already accept that retail Bitcoin SHA-256 mining at residential rates does not work, and who can either access cheap power or are willing to hold a directional position on Dogecoin. That is a smaller cohort than "all home miners," but it is a real one, and the L9 is the right machine to express the bet.
Daily revenue: $3.40. Daily power cost: 3.4 kW × 24 hours × $0.13 = $10.61. Daily net: minus $7.21. Annualized: minus $2,632.
At residential rates above $0.10/kWh, the L9 mines at a hard loss. The economics do not work at any LTC or DOGE price within a normal trading range. For DOGE alone to push this scenario into break-even, DOGE would need to roughly triple to approximately $0.60. That is possible but not a base case to plan around.
Hosted at scale: $0.075/kWh (MillionMiner Tier 3, 10+ unit deployment) Daily revenue: $3.40. Daily power cost: 3.4 kW × 24 hours × $0.075 = $6.12. Daily net: minus $2.72. Annualized: minus $993.
Even at hosted Tier 3 pricing, the L9 still loses on raw daily power math at current LTC and DOGE prices. The honest read here is that current Scrypt difficulty (91.99M, near record highs per CoinWarz, with a hashrate of 2.32 PH/s as of April 25 2026) combined with depressed LTC and DOGE prices has compressed margins across the entire Scrypt mining ecosystem. The L9 is not exempt.
Where the math flips at this rate: when DOGE moves higher. At DOGE $0.30 (a 50 percent move from current), the daily revenue rises to roughly $4.40, which produces a daily profit of approximately $1.04 net of $0.075 power. At DOGE $0.40, daily profit climbs toward $2.30. The Tier 3 hosted L9 is not a profit machine at current conditions; it is a profit machine in the conditional case where DOGE recovers toward its prior trading range.
Enterprise / industrial power: $0.05/kWh
Daily revenue: $3.40. Daily power cost: 3.4 kW × 24 hours × $0.05 = $4.08. Daily net: minus $0.68. Annualized: minus $248.
At sub-$0.06 industrial power, the L9 sits near break-even at current prices. Drop the power rate to $0.04 (achievable at hydro-backed industrial sites) and the same machine produces roughly $0.42/day net at current conditions. Layer in any DOGE price recovery and the profile improves rapidly.
Per the Simple Mining review: "At $0.08/kWh a 17 GH/s L9 nets roughly $2.71 per day, or about $81 per month at current hashprice. Drop the power rate to $0.07/kWh and net profit climbs to roughly $3.50 per day." Their numbers and ours diverge slightly because Simple Mining used different LTC and DOGE price snapshots; the directional conclusion is the same. Power cost is the dominant variable. The L9 rewards cheap power.
The honest framing: who should actually buy an L9
Three operator profiles where the L9 makes sense in 2026:
Profile 1: Existing L7 operator at $0.07-$0.10/kWh hosted
If you already operate L7s on a hosted contract at $0.07-$0.10/kWh and your L7s are running thin or break-even, the L9 upgrade math justifies itself on efficiency alone. The 42 percent efficiency improvement at the same power cost translates to meaningful profit at conditions where the L7 produces nothing. An L7 operator paying $0.08/kWh on 10 machines, currently breaking even, can move to 10 L9s and produce roughly $27/day net profit at current conditions, or roughly $9,800/year on the same fleet footprint.
Profile 2: Operator with sub-$0.06/kWh industrial power
If you have access to industrial power below $0.06/kWh (whether through a dedicated facility, a sovereign-backed allocation, or a private utility contract), the L9 is currently the most efficient way to convert that power into Scrypt revenue. The asymmetric DOGE upside makes the position more attractive than equivalent SHA-256 deployment at the same rate, particularly given Bitcoin’s halving cycle compresses SHA-256 economics every four years while Dogecoin’s issuance is constant.
Profile 3: Operator with conviction on DOGE
If you have a directional view that Dogecoin is undervalued at current prices and likely to recover, the L9 is the cleanest way to express that view through hashrate ownership. The math: at $0.075/kWh hosted, every $0.10 move in DOGE adds approximately $1.00/day per machine in profit. Over a 12-month period, a 50 cent DOGE recovery on a 10-machine fleet produces roughly $18,250 in additional revenue beyond current-conditions modeling. That is the option contract framing: the L9 captures upside on DOGE without requiring the operator to time entry, exit, or correlate with broader crypto market moves.
Three profiles where the L9 does not make sense:
1. Home miners at residential rates above $0.10/kWh. The math does not work, and no realistic LTC or DOGE price recovery rescues it. Migrate to hosted or do not deploy.
2. First-time miners with no existing infrastructure. The L9’s 80 dB noise, 3,000W heat dissipation, and dual-C20 power requirement make it an industrial machine, not a starter unit. Begin with hosted deployment of any flagship miner before considering a home L9 or any other retail-scale Scrypt operation.
3. Operators looking for diversification without a thesis. The L9 is a focused bet on Scrypt-pair price action plus your power cost basis. If you are buying it because someone told you "merged mining doubles your revenue," reread the math sections above. Merged mining does not double your revenue; it adds a secondary asset to your revenue mix that is structurally tied to the primary asset’s hashrate.
The Bells and Pepecoin bonus: multi-chain merged mining
The Litecoin-Dogecoin pair is the dominant Scrypt merged mining pairing, but it is not the only one. Per the BT-Miners L9 analysis, "Antminer L9 primarily mines Litecoin (LTC) and Dogecoin (DOGE), while supporting merged mining for other Scrypt-based PoW coins such as BEL (Bells) and PEP (Pepecoin) through AuxPoW-compatible pools."
Bells (BEL) and Pepecoin (PEP) are smaller Scrypt-based proof-of-work chains that have implemented AuxPoW to piggyback on Litecoin’s mining infrastructure. The same way Dogecoin used Litecoin to bootstrap its security in 2014, these newer chains are using Litecoin in 2025-2026. Some merged mining pools support adding BEL and PEP rewards on top of standard LTC + DOGE earnings.
Honest framing: the additional revenue from BEL and PEP merged mining is small in absolute terms (typically 1-3 percent of total daily revenue) but it represents free upside if you select a multi-chain merged mining pool. The chains are highly speculative on price and may not exist in their current form 12 months from now. Treat them as lottery tickets that come bundled with your base LTC/DOGE operation.
For most operators, the simpler path is to stick with a Litecoinpool or F2Pool merged mining setup that handles LTC + DOGE cleanly and ignore the smaller chain optionality. Operators with conviction on emerging Scrypt chains can configure pool support for BEL and PEP through specialized providers, accepting the operational complexity in exchange for the marginal additional exposure.
Hosted L9 versus home L9: the practical decision
The L9’s noise profile (80 dB under load), heat output (~3,000W), and electrical requirements (dual-C20, requires two dedicated 240V circuits or one industrial circuit) eliminate residential deployment for almost everyone. The exceptions are operators with detached outbuildings, garages with dedicated electrical service, or rural locations with industrial-grade power available.
For everyone else, hosted deployment is the realistic path. Our hosting cost breakdown covers the four-tier MillionMiner pricing structure. The relevant tiers for L9 deployment: 1. Tier 2 (5-9 units): $0.075/kWh + $5/month standing fee per unit. Effective rate at 6 L9s: roughly $0.0768/kWh. 2. Tier 3 (10+ units): $0.075/kWh, no standing fee. The same rate as Tier 2 base but without the per-unit monthly fee. 3. Enterprise (50+ units): Negotiated below the public Tier 3 rate. For larger Scrypt operators, this is the relevant pricing band.
Hosted deployment also handles the noise problem (industrial facility, no residential proximity), the heat problem (engineered cooling), the electrical problem (three-phase industrial supply), and the repair problem (12-month warranty included in the hosting tier). For an operator running 5+ L9s, hosted is the obvious choice on operational grounds alone, even before the power cost differential against residential rates.
For operators with sub-$0.06/kWh power available privately (rare in retail; common at industrial scale), self-hosting can produce better unit economics than third-party hosting. The math depends on facility costs amortized across the fleet. At 50+ L9s with private $0.05/kWh power, self-hosting typically beats Tier 3 hosting on direct economics; below 20 units, the operational overhead usually pushes self-hosting net-negative versus third-party hosting at $0.075.
Frequently asked questions
Can you really mine Litecoin and Dogecoin at the same time?
Yes. The mechanism is called Auxiliary Proof of Work (AuxPoW), introduced to Dogecoin in August 2014. A Scrypt ASIC like the Antminer L9 produces a hash that satisfies Litecoin's difficulty target. The same hash, packaged with a small AuxPoW header, can simultaneously satisfy Dogecoin's difficulty target. You earn LTC and DOGE rewards from one machine, with no efficiency loss on either chain. This works because both networks use the same Scrypt hashing algorithm.
Does merged mining reduce my Litecoin earnings?
No. Merged mining does not split your hashrate. The same computational work that produces a Litecoin hash gets reused on Dogecoin. Your Litecoin block-finding probability is identical whether you mine LTC alone or LTC + DOGE merged. The Dogecoin rewards are pure additional revenue with no offsetting cost in either electricity or hashrate. This is the structural feature that makes AuxPoW different from "profit-switching" pool strategies that move hashrate between chains.
What is AuxPoW in simple terms?
AuxPoW (Auxiliary Proof of Work) is a protocol that lets one blockchain (the auxiliary chain, like Dogecoin) accept proof-of-work performed on another blockchain (the parent chain, like Litecoin) as valid for its own block production. The auxiliary chain checks a small header attached to the parent chain's mining solution. If the math validates, the auxiliary chain accepts the block as found. Per Tari Labs technical documentation, "the Parent blockchain does not need to be aware of the AuxPoW logic, as blocks submitted to it are still valid blocks."

Why does Dogecoin have no supply cap and how does that affect mining?
Dogecoin's monetary policy fixes new issuance at 10,000 DOGE per block forever, with no halving cycles. That produces approximately 5 billion new DOGE per year permanently. Per Charlie Lee's 2014 Reddit AMA: "Using the startup analogy, imagine if Coinbase paid 95% of its equity to its employees hired in its first year, how can it hire good people after its first year?" The implication for miners: DOGE rewards do not compress over time the way Bitcoin block subsidies do. The trade-off: continuous issuance creates structural downward pressure on DOGE price in the absence of demand growth. Mining DOGE is a bet that demand grows faster than supply.
Should I host my L9 or run it at home?
For most operators, host. The L9 produces 80 dB of noise (lawnmower territory), dissipates roughly 3,000W of heat, requires dual-C20 power inputs (two dedicated circuits), and runs 24/7. Residential deployment requires a detached outbuilding or industrial-grade garage, and even then the noise typically violates municipal ordinances.
