Goldshell vs IceRiver vs Jasminer: Which Altcoin ASIC Is Right for You?

Bitcoin has Bitmain, MicroBT, and Canaan battling it out for market share. The altcoin ASIC space has its own set of dominant players — Goldshell, IceRiver, and Jasminer — each targeting different algorithms and different coins. If you're looking to mine something other than Bitcoin and you're trying to work out which brand and machine to buy, this guide cuts through the marketing and gives you an honest comparison.

Why Altcoin ASICs Are a Different Purchase Decision

Buying an altcoin ASIC is fundamentally different from buying a Bitcoin miner. With Bitcoin, you're comparing machines that all run SHA-256 — the algorithm is fixed, the coin is fixed, and the only variables are hashrate, efficiency, and price. With altcoin ASICs, the algorithm is baked into the hardware itself. A Kaspa miner cannot mine Siacoin. A Siacoin miner cannot mine Ethereum Classic. You're not just buying hardware — you're making a bet on a specific coin and its long-term mining economics.

This makes due diligence on the underlying coin at least as important as the hardware specs. With that said, the brands covered in this guide — Goldshell, IceRiver, and Jasminer — are the most established altcoin ASIC manufacturers shipping to Australia in 2026, and understanding their product philosophies helps you make a better decision regardless of which coin you're targeting.

Goldshell: Home-Friendly Builds, Multiple Algorithms

Goldshell has carved out a strong position in the home miner segment. Their machines are typically smaller, quieter, and more power-efficient than industrial-class altcoin ASICs — a deliberate design choice that makes them well-suited to Australian home environments where noise and electricity consumption are real constraints.

Goldshell produces miners across a range of algorithms, covering Scrypt (Litecoin/Dogecoin), Blake3 (Siacoin/Handshake), and others. The build quality is solid, the companion software is reasonably polished, and Goldshell's longer track record in the altcoin space means there's more community support and documented troubleshooting available compared to newer entrants.

Goldshell SC-LITE — Siacoin (Blake3)

The Goldshell SC-LITE mines Siacoin using the Blake3 algorithm, producing 4.4 TH/s at 950W. It's a mid-sized unit — larger than Goldshell's ultra-compact home miners but still manageable for a home or small office setup with adequate ventilation.

Siacoin (SC) is the native currency of the Sia decentralised storage network. Mining SC means participating in the security of a storage-focused blockchain — a different value proposition from simply mining a currency. The SC market is smaller and more volatile than Bitcoin, which means both the risks and the potential rewards are amplified compared to Bitcoin mining.

At 950W, the SC-LITE draws significantly more power than the smallest altcoin miners — this is an important consideration for Australian home miners. At $0.30/kWh, continuous operation costs approximately $205/month in electricity alone, so profitability modelling against current SC prices before purchase is essential.

Best for: Miners specifically interested in Siacoin and the Sia ecosystem, who have access to reasonable electricity rates or can offset costs with solar, and who want the backing of Goldshell's established brand.

IceRiver: Kaspa-Focused, Efficiency-First

IceRiver emerged as a major force in the altcoin ASIC market on the back of Kaspa's rapid rise. The brand is almost entirely oriented around KHeavyHash — the algorithm that powers Kaspa (KAS) — and has built a strong reputation for producing efficient, reliable machines in this niche.

Their product line spans from ultra-compact home miners drawing under 100W all the way to high-hashrate commercial units. The KS-series nomenclature (KS0, KS1, KS2, KS3, and so on) generally tracks power consumption and hashrate, with KS0 variants being the most accessible for home miners.

IceRiver KS0 Ultra — Kaspa (KHeavyHash)

The IceRiver KS0 Ultra is one of the most home-friendly altcoin ASICs available in Australia. It produces 400 GH/s on the KHeavyHash algorithm at just 100W — making it one of the lowest-wattage ASIC miners in our entire range.

At 100W continuous, monthly electricity cost at Australian residential rates ($0.30/kWh) is approximately $21–$22/month — a figure that keeps the cost of participation genuinely manageable. The machine is compact and quiet, designed to run in a home environment without dedicated cooling or ventilation infrastructure.

Kaspa itself is one of the more technically interesting proof-of-work projects in the altcoin space, using a blockDAG structure (PHANTOM/GhostDAG protocol) that allows for much higher block rates than traditional blockchain architectures. Whether that translates to long-term mining value depends on KAS price, network growth, and difficulty trajectory — all factors to research independently before committing capital.

Best for: Home miners interested in Kaspa who want low power draw, quiet operation, and a compact form factor. Those who want to enter altcoin ASIC mining with a relatively low ongoing electricity commitment.

iPollo: Ethereum Classic and Niche Algorithm Specialists

iPollo occupies a specific niche in the altcoin ASIC market: Ethereum Classic (ETC) and related ETCHash/EtHash algorithm mining. With Ethereum's move to proof-of-stake in 2022, a significant portion of GPU mining hashrate migrated to Ethereum Classic, driving demand for dedicated ETC ASIC hardware. iPollo was among the first manufacturers to release purpose-built ETC ASICs and remains a leading brand in this space.

Their hardware tends toward server-style form factors — 1U or 2U rack units rather than desktop boxes — which suits data centre or garage rack deployments more than bedroom shelves. That said, the V2X is compact enough to operate in a home setting with appropriate ventilation.

iPollo V2X — Ethereum Classic (ETCHash)

The iPollo V2X mines Ethereum Classic at 1,200 MH/s on the ETCHash algorithm, drawing 165W. The efficiency figure — approximately 0.138 W/MH — is strong for an ETC ASIC, and 165W is a manageable power draw for a home setup.

At $0.30/kWh Australian residential rates, monthly electricity cost for the V2X sits at approximately $36/month continuous. ETC mining profitability depends heavily on the ETC/AUD exchange rate and current network difficulty — both of which have shifted considerably as ASIC hardware displaced GPU miners on the ETCHash network.

Ethereum Classic has a fixed supply schedule (similar to Bitcoin's) and a committed development community, but it remains a smaller-cap asset with correspondingly higher price volatility than Bitcoin. As with all altcoin ASICs, understanding the underlying asset's fundamentals is as important as the hardware specs.

Best for: Miners specifically targeting Ethereum Classic who want a dedicated ASIC rather than GPU mining. Those with existing rack infrastructure or a suitable home space for a server-style unit.

Jasminer: High-Density ETC Mining for Serious Operators

Jasminer is a Chinese manufacturer that entered the ETC ASIC market with an unconventional approach: server-format, high-density mining hardware using their own proprietary chip architecture. Jasminer machines are typically physically larger than competitors' offerings and draw more power, but they compensate with high absolute hashrate and a distinctive thermal design.

Jasminer's brand positioning is toward semi-commercial and commercial operators rather than home hobbyists — their hardware requires more space, more airflow, and more careful power planning than compact home miners.

Jasminer X4-Q — Ethereum Classic (EtHash)

The Jasminer X4-Q is a 3U server-format ETC miner producing 1,040 MH/s on the EtHash algorithm at 480W. The form factor is a full rack server unit — this is not a desktop or shelf miner. It requires rack mounting or at minimum a stable surface with clear airflow on all sides, and it produces meaningful heat and fan noise under load.

At 480W continuous, monthly electricity at $0.30/kWh is approximately $104/month — a significant operating cost that demands careful profitability modelling before purchase. The X4-Q's strength is its hashrate density relative to its footprint in a rack environment, where power and space efficiency matter more than noise or form factor.

Compared to the iPollo V2X (1,200 MH/s at 165W), the X4-Q produces slightly less hashrate at nearly three times the power draw. The X4-Q's value proposition lies more in its proven reliability over sustained operation and Jasminer's warranty support than in outright efficiency figures.

Best for: Semi-commercial or commercial operators with rack space, adequate power infrastructure, and the ability to manage the higher ongoing electricity cost. Not recommended for residential home environments without dedicated space and ventilation.

Head-to-Head: Brands and Machines Compared

Here's how the key specs compare across the machines covered in this guide:

Note: Monthly power cost estimates assume 24/7 continuous operation at $0.30/kWh. Your actual rate will vary by state and tariff. Always model profitability using your specific electricity rate and current coin prices before purchasing.

Which Brand Is Right for You?

The honest answer is that the coin comes first, the brand second.

If you want to mine Kaspa, IceRiver is the dominant manufacturer and the KS0 Ultra is the right starting point for Australian home miners on high electricity rates — its 100W draw is among the lowest in the altcoin ASIC space.

If you want to mine Siacoin, Goldshell is the established name in Blake3 hardware, and the SC-LITE is a credible mid-range option — but the 950W draw means electricity costs are a serious factor at Australian residential rates.

If you want to mine Ethereum Classic, you're choosing between iPollo and Jasminer. For home environments, the iPollo V2X is the clear winner on efficiency and form factor. For rack-based commercial deployments where absolute hashrate density and proven uptime matter more, the Jasminer X4-Q has its place.

In all cases: research the coin, model your electricity costs honestly, and don't commit capital to altcoin mining hardware without understanding that the underlying asset price is the variable most likely to determine your outcome.
