Dogecoin and Litecoin run on the same Scrypt algorithm, which means a single ASIC mines both coins simultaneously through merge mining. This dual-coin payout structure has made Scrypt one of the most consistently profitable algorithms outside Bitcoin throughout 2025 and into 2026. The category lists 60 current models from Bitmain (Antminer L7, L9, L11), VolcMiner (D1 Hydro), Goldshell, and ElphaPex. The ElphaPex DG Hydro 1 (20 GH/s) is a hydro-cooled Scrypt miner from a newer manufacturer that has built a strong reputation among hosting operators since launch. Bitmain's L11 series remains the highest-efficiency air-cooled option for home and small-facility deployments, while the L9 holds its place as the value pick for buyers prioritising payback speed over raw efficiency. Scrypt hardware has historically held resale value better than mid-tier SHA-256 because the manufacturing pipeline produces fewer units per generation. Buyers planning a 2 to 3 year hold often see stronger residual value at exit compared with comparable Bitcoin hardware. Every miner ships DDP and qualifies for hosting at MillionMiner's US facilities.

Litecoin and Dogecoin share the same proof-of-work algorithm: Scrypt. This means a single Scrypt ASIC miner simultaneously mines both LTC and DOGE through a process called merge mining — earning rewards on two separate blockchains with no additional hardware or electricity cost. It is one of the most capital-efficient setups available in ASIC mining, and the reason Scrypt miners remain among the most popular machines we sell.

Charlie Lee releases Litecoin as a faster, lighter Bitcoin alternative. Scrypt algorithm chosen specifically to resist ASIC dominance.
Despite the ASIC-resistance intent, dedicated Scrypt ASICs emerge. Litecoin network hashrate explodes as custom silicon takes over from GPUs.
Litecoin becomes the first major coin to activate Segregated Witness, proving the technology before Bitcoin adopted it months later.
Block reward drops from 25 to 12.5 LTC. Network survives, price appreciation historically preceded and followed the event.
Reward reduces to 3.125 LTC — the current block reward. Merge mining with DOGE keeps miner revenue strong despite lower LTC subsidy.
Billy Markus and Jackson Palmer create Dogecoin as a joke based on the Shiba Inu meme. Uses Scrypt — immediately compatible with LTC mining hardware.
Dogecoin activates merge mining with Litecoin (AuxPoW). Miners now earn both LTC and DOGE simultaneously at no extra cost.
Elon Musk tweets drive DOGE to all-time highs. Daily transaction volume surges. The network proves it can handle real-world scale.
DOGE accepted as payment by Tesla and other merchants. Growing ecosystem signals transition from meme to real-use currency.
DOGE block reward remains fixed at 10,000 DOGE — no halving. Infinite supply design means miner rewards never decrease, providing long-term income certainty.
Merged mining — technically called Auxiliary Proof of Work (AuxPoW) — is a protocol that allows a single miner to submit valid proof-of-work to multiple blockchains that share the same algorithm simultaneously. Dogecoin activated AuxPoW with Litecoin in 2014, and since then every Scrypt ASIC miner has been able to earn both LTC and DOGE from a single machine running a single pool connection.
The key insight is that merge mining does not split your hashrate. Your miner submits the exact same proof-of-work computation to both networks. When a solution meets Litecoin's difficulty target, it also counts as valid work for Dogecoin. You are not doing extra work — you are simply claiming rewards on both chains for the same work you were already doing.
In practice, the vast majority of Scrypt mining pools — including Litecoinpool.org, Antpool, F2Pool, and ViaBTC — support merge mining automatically. You configure your miner once with the pool's Scrypt endpoint, and both LTC and DOGE payouts appear in your dashboard. No second configuration. No split hashrate. Just two income streams from one machine.

Originally designed to be memory-hard and ASIC-resistant, Scrypt is now the foundation of a mature, efficient ASIC mining ecosystem powering two of the top-10 cryptocurrencies by market cap.
Scrypt was originally created by Colin Percival and requires large amounts of memory to compute. This memory-hard property was intended to level the playing field between CPUs, GPUs, and FPGAs — but custom ASIC manufacturers eventually solved the memory challenge with dedicated high-bandwidth memory chips.
Under the hood, Scrypt uses PBKDF2 (Password-Based Key Derivation Function 2) combined with the Salsa20/8 stream cipher as its core mixing function. The algorithm repeatedly accesses a large pseudorandom memory array, making shortcut attacks impractical. Modern Scrypt ASICs implement this entire pipeline in optimised silicon.
Scrypt ASIC development has been ongoing since 2013. Today's machines from Bitmain (Antminer L9), MicroBT (WhatsMiner M66S-Scrypt), and iPollo represent over a decade of silicon refinement. The result is extremely efficient hardware measured in J/MH — the best units operate below 0.3 J/MH.
Pool payouts arrive in your separate LTC and DOGE wallets on a daily schedule. Both assets land on-chain in your self-custody addresses — no intermediary, no IOU. Two wallets funded automatically from one machine running 24/7.
Both use Scrypt. Both are mineable simultaneously. But their supply models, communities, and use cases are very different.
The key takeaway: LTC has a hard supply cap and halving schedule like Bitcoin, giving it scarcity characteristics. DOGE has a fixed block reward forever, giving miners long-term income stability with no reduction events — ever.
Litecoin halvings reduce the LTC block subsidy by 50% every 840,000 blocks — approximately every four years, mirroring Bitcoin's schedule. Each halving reduces your LTC income per block by half. However, the fact that you simultaneously earn DOGE (which never halves) means your total Scrypt mining revenue is never as exposed to a single halving event as a pure Bitcoin miner would be.
Dogecoin's fixed 10,000 DOGE per block is hardcoded and will never change. There is no halving, no fifthening, no emission schedule to model. This permanence makes DOGE mining revenue highly predictable in coin terms — your daily DOGE output depends only on your share of the network hashrate, not on any scheduled reward change.
The combination of LTC's scarcity-driven price potential and DOGE's stable high-volume output makes Scrypt mining a uniquely balanced income profile compared to single-coin alternatives.
Genesis era. Original reward. GPU and early ASIC mining dominated.
First halving. Network survived and continued growing. ASICs firmly established.
Second halving. Merge mining with DOGE cushions the revenue impact for miners.
Third halving. Current reward. DOGE merge mining at full scale — miners earn both assets.
Fourth halving (projected). Scrypt miners will still earn full DOGE rewards simultaneously.
DOGE Block Reward
10,000 DOGE per block. Fixed forever. No halving. Ever.
Scrypt ASICs are among the most accessible miners for home setups. Mid-range units like the Antminer L7 consume around 3,425W — comparable to a large Bitcoin ASIC — and can realistically run in a garage or basement with standard ventilation. Smaller units in the Antminer L-series offer lower wattage options for tighter spaces.
The dual-income nature of Scrypt mining gives home miners an important advantage: even during periods of LTC price weakness, DOGE rewards continue flowing at the same rate. This natural diversification makes Scrypt mining somewhat more resilient than single-coin alternatives for home operators who cannot quickly react to market conditions.
At industrial scale, the dual-revenue stream of Scrypt mining becomes a significant advantage over single-coin operations. A fleet of 50 Antminer L9 units earns LTC and DOGE simultaneously — providing two separate assets to manage, hold, or convert based on market conditions. Operators can choose to hold LTC for its halving-driven scarcity thesis while converting daily DOGE output to cover operating costs, creating a natural hedging structure.
Industrial power contracts at $0.03–$0.05/kWh transform Scrypt mining margins. An L9 at 3,360W costs roughly $3.23/day at $0.04/kWh — significantly less than at residential rates — and earns both LTC and DOGE rewards every single block.
Three metrics determine which Scrypt ASIC is right for your setup — and all three affect both your LTC and DOGE earnings simultaneously.
Scrypt hashrate is measured in MH/s (megahashes per second) or GH/s for top-tier machines. The Antminer L9 leads the market at 16,000 MH/s. More MH/s means a larger proportional share of both LTC and DOGE block rewards every day — the metric applies equally to both coins.
Affects LTC + DOGE equallyScrypt miner efficiency is measured in joules per megahash (J/MH). Top current machines like the Antminer L9 run at approximately 0.21 J/MH. Older units from the L7 generation run at 0.33 J/MH. The gap compounds significantly over a year — always prioritise efficiency alongside raw hashrate.
Lower = Cheaper to RunWhen calculating ROI for a Scrypt miner, include both your daily LTC and DOGE revenue. Use a mining profitability calculator that supports merge mining — single-coin calculators will significantly underestimate your actual earnings. Combined revenue often improves ROI windows by 30–60% compared to LTC-only projections.
Calculate Both CoinsScrypt mining profitability has more moving parts than single-coin mining — but also more resilience. Here are the five variables every LTC/DOGE miner needs to understand.
Litecoin has a strong historical correlation with Bitcoin price movements — when BTC rallies, LTC typically follows. However LTC also has its own halving cycle which can act as an independent catalyst. During LTC bear markets, the DOGE revenue stream provides a meaningful floor for miner income that pure-LTC projections miss entirely. Model your LTC revenue conservatively and treat any upside as a bonus.
Dogecoin is highly volatile and can swing 50–100% in short periods driven by social media momentum, celebrity endorsements, and broader market sentiment. At 10,000 DOGE per block with approximately 1,440 DOGE blocks per day, the network distributes around 14.4 million DOGE daily across all miners. At even modest DOGE prices, this creates substantial daily income that frequently exceeds LTC rewards in fiat value. Tracking both LTC/USD and DOGE/USD independently is essential for accurate profitability modelling.
Because LTC and DOGE share the same Scrypt hashrate pool, difficulty growth on the LTC network simultaneously reduces your share of DOGE rewards (since your relative hashrate share shrinks). As new Scrypt ASICs deploy globally, network difficulty grows and each machine earns proportionally less of both coins. Always model with a higher difficulty assumption than today — network growth has been consistent year over year.
An Antminer L9 draws 3,360W. At $0.04/kWh that is $3.23/day in power cost. At $0.12/kWh it is $9.68/day — a difference of $6.45 per day, or over $2,350 per year per machine. Securing industrial power is particularly impactful for Scrypt miners because the dual-coin revenue stream means the absolute profit delta from cheap power is larger than for single-coin operations of comparable wattage.
The LTC halving reduces your LTC block reward by 50% every ~4 years. The next halving (projected ~2027) will cut the LTC portion of your revenue in half. However — and this is the key difference from Bitcoin mining — your DOGE rewards are completely unaffected by LTC halvings. The DOGE portion of your income continues unchanged regardless of how many LTC halvings have occurred. This asymmetry makes Scrypt mining progressively more DOGE-weighted over time, which is either an advantage or a risk depending on your view of each asset.
The most important thing to verify when choosing a Scrypt pool is whether it supports merge mining — most major pools do, but always confirm before pointing your hashrate. A pool that only pays LTC and discards your DOGE rewards is leaving significant money on the table.
Check whether the pool pays out DOGE to a separate wallet address automatically, or whether you need to configure it separately. Some pools use a unified Scrypt endpoint that handles both coins internally; others require a second worker configuration. Read the pool's setup guide carefully before connecting your hardware.

Scrypt mining has unique quirks — especially around merge mining setup. Avoid these before plugging in.
Not Enabling Merge Mining
This is the single most costly mistake a Scrypt miner can make. If your pool or configuration does not have DOGE merge mining enabled, you are leaving 30–60% of your potential daily income unclaimed. Always verify your pool dashboard shows both LTC and DOGE payouts before assuming merge mining is active.
Using a Single-Coin Profitability Calculator
Standard mining calculators that only show LTC returns will dramatically underestimate your actual income. Always use a calculator or spreadsheet that models both LTC and DOGE earnings separately using current prices, or your ROI projections will be significantly pessimistic.
Ignoring the LTC Halving in ROI Models
LTC halvings every ~4 years cut your LTC block reward by 50%. Miners who model returns based on current LTC rewards without accounting for the next halving will find their projections break down mid-hardware-lifespan. Build the halving into your 4-year ROI model explicitly.
Treating DOGE as Worthless
Some miners dismiss DOGE earnings because of its "meme coin" reputation and fail to manage them actively. At current market prices, DOGE rewards frequently represent the majority of total daily miner income in fiat terms. Actively track and manage your DOGE accumulation the same way you would any other mining asset.
Underestimating Scrypt Power Draw
Top-tier Scrypt ASICs like the Antminer L9 draw 3,360W — comparable to large Bitcoin miners. Running multiple units from a standard home electrical circuit without proper wiring is a fire risk. Ensure your electrical infrastructure matches the load before deploying more than 1–2 machines at home.
Skipping Pool Latency Checks
With LTC's 2.5-minute and DOGE's 1-minute block times, stale shares from high-latency pool connections cost you real money. Always choose a pool with servers geographically close to your hardware and monitor your stale share rate in the pool dashboard after setup.
