Kadena miners (Blake2s)
ASIC miners for Kadena (KDA), Blake2s algorithm – for example the iBeLink BM-K3 Max. For every machine you can see its hashrate, power draw and returns in CZK, recalculated for today's network difficulty and exchange rate.
Kadena runs on dozens of parallel chains (Chainweb), so blocks are produced all the time. The KDA price is low today – before you buy, ask us about the real returns after electricity costs.

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 Kadena 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.
3 models in this collection, most profitable per 1 kWh:
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.
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.

Kadena 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 |
|---|---|---|---|---|---|---|---|---|
| Antminer KA3 | 166 TH/s | 3,154 W | 19.0 J/TH | Air | 80 dB | from 38 441 Kč | 99.25 Kč | 12.94 Kč |
| iBeLink BM-K3 Max | 82 TH/s | 3,200 W | 39.0 J/TH | Air | 75 dB | from 54 531 Kč | 49.03 Kč | −38.54 Kč |
| iBeLink BM-K3 Mini | 5 TH/s | 290 W | 58.0 J/TH | Air | 35 dB | from 11 766 Kč | 2.99 Kč | −4.95 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.
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 KA3.
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: −241 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: 12.94 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 Kadena miners
What is Kadena and how is it mined?
Kadena (KDA) is the Chainweb proof-of-work network, made up of dozens of chains mined in parallel, so it handles more transactions than a classic blockchain. It is mined with the Blake2s algorithm on ASIC miners.
How much does a Kadena miner earn per day?
Revenue depends on the machine's hashrate, network difficulty and the KDA exchange rate. We recalculate the current value in Kč every hour and show it on each machine's card – it is today's figure before electricity costs, not a guarantee for the future.
Can I place a Kadena miner in your hosting?
Yes, we place the machines in a data centre with cheaper electricity and take care of their operation. Prices by location are on the page Miner hosting.
