Bitmain Antminer KA3 ROI

Assuming you buy this miner from for $10,899, the Bitmain Antminer KA3 can mine 19.05181129 KDA per 24 hours, and the current KDA price is $0.97, the daily revenue from mining KDA would be:

Daily Revenue = 19.05181129 KDA * $0.97 = $18.47

To calculate the ROI of the Antminer KA3, we also need to consider the following factors:

  1. Power Consumption: The Antminer KA3 has a power consumption of 3250W.
  2. Electricity Cost: The electricity cost is given as 6 cents/kWh.
  3. Maintenance Cost: The maintenance cost includes costs such as pool fees, cooling costs, and other expenses associated with running the miner.

Assuming a daily power cost of:

Daily Power Cost = Power Consumption * Electricity Cost * 24 / 1000

Daily Power Cost = 3250 * 0.06 * 24 / 1000

Daily Power Cost = $4.68

Assuming a daily maintenance cost of $1, the daily expenses of running the miner would be:

Daily Expenses = Daily Power Cost + Daily Maintenance Cost Daily Expenses = $4.68 + $1 Daily Expenses = $5.68

To calculate the ROI of the Antminer KA3, we can use the following formula:

ROI = (Cost of Miner + Daily Expenses) / Daily Revenue

Assuming a cost of the Antminer KA3 of $10,899, the ROI would be:

ROI = ($10,899 + $5.68) / $18.47 ROI = 603 days

Therefore, it would take approximately 603 days, or just over 1.6 years, to break even on the cost of the Antminer KA3 and start making a profit. It’s important to note that mining difficulty and KDA price are constantly changing, so the actual ROI may be higher or lower depending on these factors.


Given the enormous popularity of Goldshell’s KD miner series, it appears Bitmain is vying for that market share. The KA3, their very first Kadena KDA miner, is the most effective and lucrative miner in the entire globe!
