Ka3 Antminer
Overview
Product sourcing insights & recommendations
The Bitmain Antminer KA3 remains a dominant force in the Kadena (KDA) mining market, though its profitability in 2026 is heavily dependent on energy costs. Originally launched in late 2022, it effectively neutralized older competitors like the Goldshell KD series by offering a massive hashrate leap to 166–173 TH/s BitmainCaptainmining.
