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.

Bitcoin

BTC · algorithm SHA-256

The first and largest cryptocurrency. It is mined with the SHA-256 algorithm, a new block is found roughly every 10 minutes and, since the halving in April 2024, the reward is 3.125 BTC per block.

1 TH/s earns per day today

≈ 0.72 Kč BTC

BCH0.70 Kč
BSV0.63 Kč
XEC0.76 Kč
FB0.43 Kč
QUAI0.81 Kč

The miner always mines one of the coins, depending on the selected pool. Today QUAI earns the most – the revenue on the product cards uses it too.

Recalculated every hour from network difficulty and the exchange rate (last updated 4/11/2026). Before electricity costs; this is not a forecast.

Prices

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 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.

- Bitdeer SealMiner A4 Pro Air 336 TH/s · 3662 W from 150 933 Kč
- Antminer S23 318 TH/s · 3498 W from 156 884 Kč
How hosting works
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.
48 models in this collection, most profitable per 1 kWh:
- Antminer S23 XP Hyd 600 TH/s · 5340 W from 324 585 Kč
- Bitdeer SealMiner A4 Ultra Hyd 886 TH/s · 8372 W from 221 508 Kč
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.

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.

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 – 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: −89.92 Kč / day

Quiet miners for flats and houses Soundproof box

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: 341 Kč / day

How hosting works Prepaid electricity Calculate profit

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.

Bitcoin mining with ASIC miners

Bitcoin is mined with the SHA-256 algorithm. A new block is found roughly every ten minutes and, since the halving in April 2024, the network pays 3.125 BTC for it plus transaction fees. Miners all over the world compete for the reward, which is why Bitcoin today is mined exclusively on ASIC miners – specialised machines with hashrates in the hundreds of TH/s.

When choosing, focus above all on efficiency in J/TH. The new Antminer S21 series uses roughly half as much energy per 1 TH/s as the older S19 – the difference in your annual electricity bill is often bigger than the difference in the machine price. Our comparison Antminer S21, S21+ and S21 Pro and the article on electricity consumption in Bitcoin mining will help.

We recalculate the earnings of all machines in the table every hour based on difficulty and the exchange rate, including other SHA-256 coins the miner can mine instead of BTC. What Bitcoin is and how mining it works is explained in the article Bitcoin (BTC), and the practical steps from purchase to payout in the guide Bitcoin mining.
