When most people think about crypto mining hardware, Bitcoin comes to mind first. But in 2026, some of the most interesting ASIC mining opportunities are on altcoin networks — particularly Kaspa, Litecoin, and Dogecoin — where dedicated hardware has matured, network difficulty is more accessible, and the right miner can be run efficiently on standard Australian residential power.
This guide covers the best altcoin ASIC miners available in Australia right now, what algorithm each one runs, and how to think about profitability before you buy.
Why Altcoin ASIC Mining in 2026?
Bitcoin mining is dominated by industrial-scale operations with access to cheap power and bulk hardware. For Australian home miners working with residential electricity rates of $0.25–$0.35/kWh, competing at the Bitcoin network's current difficulty is genuinely hard — the margins are thin even with efficient hardware.
Altcoin networks offer a different equation:
- Lower network difficulty — Kaspa, Litecoin, and Dogecoin all have smaller global hashrates than Bitcoin, meaning each unit of your hashrate represents a larger share of the network.
- Lower upfront hardware cost — Altcoin ASICs are typically cheaper to buy than flagship Bitcoin miners, lowering the barrier to entry.
- Algorithm diversity — Different algorithms (KHeavyHash, Scrypt) mean different hardware, and in some cases, hardware that runs quieter and cooler than high-wattage Bitcoin ASICs.
The tradeoff is coin price volatility and the risk that a network's economics shift. As with all mining, running the numbers at your actual electricity rate before buying is essential. Our guide on electricity prices and crypto mining in Australia is a good starting point.
Understanding Altcoin Mining Algorithms
Unlike Bitcoin — which runs exclusively on SHA-256 — altcoin networks use a range of proof-of-work algorithms. The algorithm a coin uses determines which hardware can mine it. An ASIC built for one algorithm cannot mine a coin on a different one.
The two most relevant algorithms for altcoin ASIC mining in 2026 are:
- KHeavyHash — Used by Kaspa (KAS). A relatively new algorithm designed to be memory-hard and ASIC-resistant at launch, but dedicated KHeavyHash ASICs now dominate the Kaspa network.
- Scrypt — Used by Litecoin (LTC) and Dogecoin (DOGE), which are merge-mined together on the same Scrypt network. A single Scrypt ASIC mines both coins simultaneously.

Kaspa (KAS) Mining: KHeavyHash ASICs
Kaspa launched in 2021 and has grown into one of the most actively mined proof-of-work altcoins globally. Its blockDAG architecture allows for extremely fast block times (one block per second), and its KHeavyHash algorithm has attracted a dedicated ASIC hardware ecosystem.
Kaspa's network difficulty has risen substantially as ASICs replaced GPU miners, but the barrier to entry remains lower than Bitcoin — and compact, low-wattage Kaspa miners are well-suited to Australian home setups.
IceRiver KS0 Ultra — 400 GH/s, 100W
The IceRiver KS0 Ultra is our entry-level Kaspa miner and one of the most popular compact ASICs we stock. At 100W draw, it runs on a standard Australian wall outlet without any dedicated electrical work — plug it in, connect it to your router, and it starts mining KAS.
- Algorithm: KHeavyHash
- Hashrate: 400 GH/s
- Power draw: 100W
- Noise level: Low — suitable for home or office use
- Form factor: Compact desktop unit
The KS0 Ultra is a good fit for miners who want to get started with Kaspa without committing to high upfront hardware cost or significant electrical infrastructure. At 100W, your daily power cost at $0.30/kWh is around $0.72 — one of the lowest operating costs of any ASIC in our range.
Litecoin & Dogecoin Mining: Scrypt ASICs
Litecoin and Dogecoin are merge-mined on the same Scrypt proof-of-work network. This means a single Scrypt ASIC earns both LTC and DOGE rewards simultaneously — you don't have to choose between them. It's one of the most capital-efficient setups in altcoin mining: one machine, two revenue streams.
Scrypt ASICs have been around since 2014 and the hardware has matured considerably. Modern Scrypt miners are efficient, reliable, and available at a range of price points and hashrates.
Fluminer L1 — 2 GH/s Scrypt, LTC + DOGE
The Fluminer L1 is a compact, low-noise Scrypt miner built for home use. It delivers solid hashrate at a modest power draw, making it one of the better-balanced options for Australian miners targeting the Litecoin/Dogecoin merge-mine.
- Algorithm: Scrypt
- Coins mined: Litecoin (LTC) + Dogecoin (DOGE) simultaneously
- Form factor: Compact desktop — low noise profile
- Best for: Home miners wanting dual LTC/DOGE income without industrial hardware
Goldshell Mini Doge III — 700 MH/s Scrypt
The Goldshell Mini Doge III is Goldshell's latest iteration of their popular Mini Doge line — a compact, near-silent Scrypt miner designed from the ground up for home use. It's one of the quietest ASICs we stock, making it a realistic option for miners who share living spaces or run hardware in bedrooms or home offices.
- Algorithm: Scrypt
- Hashrate: 700 MH/s
- Coins mined: Litecoin (LTC) + Dogecoin (DOGE) simultaneously
- Noise level: Very low — one of the quietest ASICs available
- Form factor: Small desktop box, no dedicated ventilation required
The Mini Doge III is a favourite for miners who prioritise quiet operation and minimal footprint. It won't match the hashrate of a full-size commercial Scrypt miner, but for home setups it strikes a strong balance between performance, noise, and power consumption.

Also Worth Considering: Other Altcoin ASICs
Beyond Kaspa and Scrypt, our altcoin ASIC range includes hardware for several other proof-of-work networks:
- Ethereum Classic (ETC) — The iPollo V2X (1200 MH/s ETCHash) and Jasminer X4-Q (1040 MH/s ETCHash) are dedicated ETC miners running the ETCHash algorithm.
- Siacoin (SC) — The Goldshell SC Lite mines Siacoin on the Blake2b-Sia algorithm at 4.4 TH/s, 1400W.
- Grin (GRIN) — The iPollo G1 Mini mines Grin on the Cuckatoo32 algorithm at 1.2 GH/s.
- Lucky Miner LG07 — The Lucky Miner LG07 is a compact 11 MH/s Scrypt miner — an ultra-low-cost entry point for Litecoin/Dogecoin solo or pool mining.

Altcoin Mining Pools vs Solo Mining
For most altcoin miners, joining a mining pool is the right call. Pools combine hashrate from thousands of miners and distribute rewards proportionally — giving you frequent, predictable payouts rather than the lottery of solo block-finding.
That said, some miners — particularly those running low-wattage home units like the KS0 Ultra or Mini Doge III — choose to mine solo as a speculative play. The odds are long, but the reward for finding a solo block is the full block reward.

Thinking About Profitability at Australian Electricity Rates
Australia has some of the highest residential electricity rates in the world. In most states you'll pay between $0.25 and $0.38 per kWh — which is a meaningful operating cost when running hardware 24/7.
The compact altcoin ASICs in our range are specifically well-suited to this environment. A 100W Kaspa miner costs roughly $0.72–$1.00/day to run. A low-wattage Scrypt miner in the same class costs a similar amount. Compare that to a 3,500W Bitcoin miner at $25+ per day in electricity, and the economics are materially different.
That said, profitability is always a function of coin price, network difficulty, and your specific electricity rate — all three of which change over time. We strongly recommend modelling your numbers before purchasing. Our guide covers the detail: Home Mining in Australia: What Electricity Rate Makes It Profitable?
Should You Choose an Altcoin ASIC or a Bitcoin Miner?
There's no universal right answer — it depends on your budget, power situation, risk tolerance, and view on individual coin prospects. A few principles that tend to hold:
- Lower upfront cost, lower power draw → altcoin ASICs are more accessible for first-time home miners.
- More coin exposure diversity → altcoin mining gives you exposure to KAS, LTC, DOGE, or ETC rather than Bitcoin alone.
- Bitcoin has the deepest liquidity and most developed ecosystem — for miners who want to hold what they mine, BTC remains the most straightforward asset.
- Merge-mining Scrypt is a unique advantage — one machine, two coins, no compromise on either.
