ASIC miners · SHA-256
Bitcoin miners (SHA-256)
ASIC miners for the SHA-256 algorithm for Bitcoin mining: Antminer S19 and S21, Whatsminer, Avalon and SealMiner, air-cooled, water-cooled (Hydro) and immersion-cooled. For each model you can see the hashrate in TH/s, efficiency in J/TH and today's earnings in CZK.
The same machine can also mine other SHA-256 coins, such as Bitcoin Cash or eCash – just switch the pool. We sell miners with an invoice and warranty, service them in Prague 10, and you can place them straight in our hosting.

How to choose a Bitcoin 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.

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.

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.

The result of mining depends mainly on the electricity price. Comparison for the machine in this collection that earns the most per 1 kWh – Antminer S23 XP Hyd.
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: 14.53 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: 445 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 Bitcoin miners
How much does a Bitcoin miner earn per day?
Revenue is calculated from the machine's hashrate in TH/s and how much 1 TH/s earns today – which depends on network difficulty, the block reward and the BTC price. We show the current value for each model on its card and in the comparison table. Subtract electricity from the revenue: the switch above the listings shows the profit at your kWh price.
What does J/TH mean and why does it matter?
J/TH shows how much energy a miner uses per 1 TH/s of hashrate. The lower the number, the more bitcoin you mine from one kWh. With more expensive electricity and after a halving, efficiency decides whether a machine makes money – older machines at around 30 J/TH pay off mainly with cheap electricity.
How does the halving affect revenue?
Roughly every four years the halving cuts the block reward in half – in April 2024 it dropped to 3.125 BTC. A machine's revenue in BTC is therefore cut roughly in half overnight; the result in fiat then depends on the exchange rate. More in the article Halving.
Can I mine coins other than Bitcoin with a SHA-256 miner?
Yes. SHA-256 is also used by Bitcoin Cash, Bitcoin SV, eCash and other coins – the miner always mines whichever one you set in the pool. If one of them earns more today, we show it in the coin card at the top. You will find an overview of SHA-256 coins in the article SHA-256 coins.
Air, Hydro or immersion?
Air-cooled machines are the cheapest but loud (usually 70–80 dB). Hydro machines are liquid-cooled, quieter and more powerful, but need a water circuit and usually three-phase power. Immersion suits mining farms. You will find a comparison in the article Air vs. liquid cooling.
Is it worth mining Bitcoin at home in the Czech Republic?
At the normal grid price of electricity, usually not – powerful SHA-256 miners use more than they mine. Mining at home makes sense with cheap electricity, surplus solar power or when you use the heat. Otherwise hosting with cheaper electricity is better value. You will find the calculation in the article Bitcoin mining.
