Antminer KA3

Bitmain Antminer KA3

Bitmain Antminer KA3, introduced in September 2023, is the most powerful and with the effectivity 19 W/Th most efficient ASIC miner for mining of cryptocurrency Kadena. Antminer KA3 offers 137% higher performance than the second most powerful miner for this algorithm (iBeLink BM-K3).

Technical parameters of the miner

Cooling is taken care of by two fans on the front, which draw cold air into the miner, and two fans on the back, which take the now warm air away again. The manufacturer Bitmain gives a 6-month warranty for the miner. The package includes the Antminer KA3; an Ethernet cable to connect to the network; two power cables and a filter grid to prevent dust from settling on the mining chips and extend its life. The dimensions and weight of the device are 43 x 19.5 x 29 cm (16.1 kg).

Soundproofing of the miner

You can buy a Silent box that can be added to the miner, which can reduce the noise level from 75 dB to a level where you can operate the miner from the comfort of your home without any problems. The turbine will provide more optimal cooling than standard fans, reducing electricity consumption and extending the life of the miner.

In addition, the box comes with a set of extensions and tubes that allow you to exhaust warm air directly from the miner and use the residual heat to heat your home. This solution gives home cryptocurrency mining a whole new dimension, saving you hundreds of Euros a year in heating costs. Another advantage is the smart app that you can use to control the basic settings of the box. Of course, there are also chips that shut down the miner in case of overheating or fan failure.

Recommended mining pools

For Bitcoin mining we recommend antpool.com and F2Pool.com. How to get started and set up for the first time? Find out everything you need to know in the mining tab.

Miner hosting

Mining cryptocurrencies in your home makes sense mainly when you have access to cheap electricity (e.g. from surplus energy from a photovoltaic plant) or when mining along with using the surplus heat to heat your home. In case you do not have access to a source of cheap electricity, we recommend using hosting in our data centre abroad. The cost of electricity is only $0.09/kWh, so with us you can save thousands of Euros a year on your mining operation. We will take care of the purchase, shipping, clearance, initial start-up and setup, and regular maintenance of your miner. So the only thing you have to do is choosing your miner.

Kadena halving

The advantage of Kadena mining is slower and smoother "halving" (periodic reduction of the reward for the mined block - e.g. for BTC 50% once per 4 years). The reduction of the reward for the mined block is more frequent but not so high, so miners don´t have to worry about profitability after halving.
