ASIC miners · Etchash
Ethereum Classic miners (Etchash)
ASIC miners for Ethereum Classic (ETC), which is mined with the Etchash algorithm – a modified version of Ethash. Well-known machines include the Antminer E9 Pro and E11, iPollo V2 and Jasminer X16-Q.
We do not currently offer an Etchash model. Below you will find previously sold machines as archive cards with specifications and a contact form – we will check availability or suggest an alternative. Ethereum Classic can also be mined on graphics cards, see graphics card profitability.

Profit = today’s revenue based on network difficulty and the exchange rate − electricity at the selected price. Our hosting = the cheapest location with free capacity (Nigeria #2), price converted from USD at today’s exchange rate. Revenue changes; this is not a forecast.

How to choose a Ethereum Classic miner
First decide where the machine will run – that determines the cooling. For each type we show the machines from this collection that earn the most today from 1 kWh of electricity.
-
hosting, workshop
Air-cooled
The most common and cheapest option: fans cool the machine, so it only needs a supply of cool air and a way to remove the heat. It is loud, though (usually 70–80 dB), so it does not belong in a flat – it suits our hosting, a workshop or a plant room, and at home only with a soundproof box.

quieter, heat for heating
Hydro (water cooling)
A liquid in a closed loop cools the chips and a dry cooler or heat exchanger removes the heat. Hydro machines are quieter and more powerful, but they need a water loop and usually a three-phase supply. You can use the heat to warm water or for heating.
There are none in this collection right now. Write to us – we will check availability.
Water loops for Hydro -
farms, almost silent
Immersion cooling
The machine is submerged in dielectric fluid in an immersion tank – it is almost silent and the chips stay at an even temperature. It needs a tank, a pump and a cooler, so it is best suited to farms and hosting.
There are none in this collection right now. Write to us – we will check availability.

Ethereum Classic miner comparison
Sorted from the most efficient – fewest joules per unit of hashrate. We recalculate revenue every hour, and profit using the electricity price selected above the miners: on hosting at 1.14 Kč/kWh.
| Model | Hashrate | Power | Efficiency | Cooling | Noise | Price from | Revenue / day | Profit / day |
|---|---|---|---|---|---|---|---|---|
| Jasminer X44-P | 23.4 GH/s | 2,550 W | 109 J/GH | Air | – | from 246 330 Kč | 207 Kč | 137 Kč |
| Bombax EZ100-PRO | 15.5 GH/s | 3,100 W | 200 J/GH | Air | – | from 48 446 Kč | 137 Kč | 52.04 Kč |
| Antminer E11 9.5 GH/s | 9.5 GH/s | 2,470 W | 260 J/GH | Air | 75 dB | from 48 250 Kč | 83.89 Kč | 16.30 Kč |
| Jasminer X16-QE | 1.85 GH/s | 620 W | 335 J/GH | Air | – | from 21 512 Kč | 16.34 Kč | −0.63 Kč |
Hashrate, power draw and noise are stated by the manufacturers. Efficiency = power draw ÷ hashrate. Revenue = hashrate × today’s revenue of the algorithm’s most profitable coin (before electricity and pool fees); profit = revenue − electricity at the selected price. For machines with several hashrate options we use the base hashrate from the product card.

Older models that we no longer offer. On the product card you will find the specifications and the calculator to compare them with current machines.
At home or on our hosting?
The result of mining depends mainly on the electricity price. Comparison for the machine in this collection that earns the most per 1 kWh – Jasminer X44-P.
At home or at your business
- Grid electricity costs a Czech household roughly 4.5–6.5 Kč/kWh (2026); it is cheaper from your own solar panels or on a business tariff.
- A powerful ASIC needs its own circuit and ventilation, and you have to expect noise – air-cooled machines are usually 70–80 dB.
- You can use the miner’s heat for heating, but in summer you have to get rid of it.
Profit at 4.5 Kč/kWh: −68.76 Kč / day
On our hosting
- Electricity from 1.14 Kč/kWh including management (Nigeria #2), 7 locations with free capacity.
- With prepaid electricity, up to 30% cheaper.
- New miners bought from us that run on our hosting come with a 7-year warranty. We take care of noise, cooling and repairs.
Profit at 1.14 Kč/kWh: 137 Kč / day
Profit = today’s revenue − electricity for 24 hours, before pool fees. Network difficulty and the exchange rate change; this is neither a forecast nor a promise of revenue.
FAQ about Ethereum Classic miners
What is Ethereum Classic?
Ethereum Classic is the original Ethereum chain, which did not carry out the hard fork after The DAO affair in 2016 and stayed with mining (proof-of-work). Like Ethereum, it supports smart contracts.
What is the difference between Ethash and Etchash?
Etchash is Ethash with a modified calculation of the DAG data structure that the miner keeps in memory. Ethereum Classic introduced it in 2020 so that the DAG grows more slowly and older devices with less memory can keep mining for longer.
Which ASIC miners exist for ETC?
Etchash machines are made by Bitmain (Antminer E9 Pro, E11), iPollo and Jasminer. You will find their specifications in the archive cards below; we are happy to check current availability for you.
Can ETC be mined on graphics cards?
Yes, Etchash is memory-intensive and graphics cards can mine it. The page Graphics card profitability shows how much they earn today.
Will you let me know when an ETC miner is in stock?
Yes, write to us using the form above or on the Contact page. For archive models you can also set an availability alert directly on their card.
