Profitability Analysis

The Bitmain Antminer KS3 requires very cheap electricity (below $0.030/kWh) to mine Kaspa profitably at current prices. It remains viable only in the lowest-cost regions globally — such as large-scale hydro-power facilities or co-located industrial mining operations.

As a dedicated ASIC, the Bitmain Antminer KS3 is permanently optimised for kHeavyHash — the algorithm used by Kaspa. It cannot be repurposed for other algorithms, so its long-term viability is directly tied to the economics of those specific coins.

Profitability at Key Electricity Rates

All figures assume constant Kaspa price ($0.03) and current network difficulty. Actual results will vary as both change over time.

How to Mine Kaspa with the Bitmain Antminer KS3

  1. Acquire and receive the Bitmain Antminer KS3

    Purchase the Bitmain Antminer KS3 from an authorised reseller or reputable secondary market. Budget approximately $1,800. Verify the unit is complete and inspect for physical damage before powering on. The unit ships ready to mine — no assembly required beyond power and network connections.

  2. Connect power and network

    Connect the Bitmain Antminer KS3 to a dedicated 3188W power supply on a 16 A+ circuit at 220–240 V. Connect an Ethernet cable to your router. Power on the unit and wait 2–3 minutes for it to boot.

  3. Configure your Kaspa mining pool

    Access the miner's web interface by entering its IP address in your browser (find it via your router's DHCP lease list). Navigate to Miner Configuration and enter your chosen pool stratum URL, your Kaspa wallet address as the worker username, and 'x' as the password. Recommended pools: K1Pool, WoolyPooly, HeroMiners.

  4. Monitor performance and optimise

    After starting, confirm your hashrate matches the expected 9.4 TH/s in the pool dashboard (allow 10–15 minutes for the pool to register your worker). Use our live Kaspa calculator to track daily earnings against your electricity cost. Consider enabling auto-tune mode or third-party firmware (BOS+ for Antminer units) to improve efficiency 5–10%.

Frequently Asked Questions

Is the Bitmain Antminer KS3 profitable for Kaspa mining in 2026?
At $0.07/kWh, the Bitmain Antminer KS3 generates approximately $-3.04 per day mining Kaspa at current prices ($0.03/coin). The break-even electricity rate is $0.030/kWh. Profitable operation requires below-average electricity costs. Use our live Kaspa calculator for updated estimates as prices and difficulty change.
What electricity rate does the Bitmain Antminer KS3 need to mine Kaspa profitably?
The Bitmain Antminer KS3 breaks even on Kaspa mining at exactly $0.0302/kWh at current network conditions. At $4 cents/kWh, the daily profit is $-0.7471; at $8 cents/kWh it is $-3.81. See the full profitability table on this page for all five electricity tiers.
What is the ROI timeline for the Bitmain Antminer KS3 mining Kaspa?
At a hardware acquisition price of approximately $1,800 and $0.07/kWh electricity, the Bitmain Antminer KS3 has an estimated ROI of N/A at current prices — the hardware is not yet cash-flow positive at this electricity rate. ROI calculations assume constant Kaspa price and network difficulty, both of which fluctuate significantly.
How does the Bitmain Antminer KS3 compare to other Kaspa miners?
The Bitmain Antminer KS3 mines Kaspa at 9.4 TH/s with 339 J/TH efficiency. There are 5 compatible hardware models for Kaspa in our database. See the comparison table below for a side-by-side efficiency and profitability breakdown of all compatible miners.
