Mining Profitability in 2026
To calculate exact daily, weekly, and monthly revenue for the Bitmain Antminer KS7, use our live Kaspa mining calculator. Enter 70 TH/s as your hashrate and 3,300 W as power consumption, then input your electricity cost per kWh. The calculator fetches live price, difficulty, and block reward data every 10 minutes from the network.
Break-even tip: Enter the approximate price of this unit (~$9,500) in the hardware cost field of the calculator to see your estimated days-to-break-even based on current network conditions.
Pros & Cons
Pros
- Over 3× the hashrate of the KS5 Pro (70 vs 21 TH/s)
- Dramatically improved kHeavyHash efficiency vs previous generation
- Standard Bitmain form factor — same power and rack infrastructure as S21
Cons
- High acquisition cost (~$8,500–$11,000 new)
- Kaspa-only — single-algorithm ASIC with no fallback coin
- High KAS network difficulty growth may compress ROI over time
Frequently Asked Questions
Is the Antminer KS7 profitable in 2026?
At $0.05+ per KAS and electricity below $0.07/kWh, the KS7 generates strong daily earnings given its 70 TH/s output. Kaspa's 1-second block time means rewards accrue smoothly and consistently. The KS7's improved efficiency over the KS5 Pro makes it more resilient to difficulty increases. Use our live Kaspa mining calculator with 70 TH/s and 3,300 W for a current profitability estimate.
How does the KS7 compare to the KS5 Pro?
The KS7 delivers more than 3× the hashrate of the KS5 Pro (70 vs 21 TH/s) at similar power draw — a transformational efficiency improvement. While the KS7's acquisition cost is significantly higher (~$9,500 vs ~$5,500 for the KS5 Pro), its far superior W/TH ratio means substantially lower electricity cost per KAS mined. For miners with cheap electricity deploying capital long-term, the KS7 is the stronger choice.
Can the KS7 mine coins other than Kaspa?
No — like all kHeavyHash ASICs, the KS7 is hard-coded for Kaspa's algorithm and cannot mine Bitcoin, Ethereum Classic, or any other coin. Kaspa's single-asset nature is the primary risk factor: if KAS price falls substantially, no algorithm switching is possible. Factor this concentration risk into your deployment decision.
What pools support the Antminer KS7?
The KS7 uses standard Stratum V1 protocol and is compatible with all major Kaspa pools: K1Pool, WoolyPooly, HeroMiners, and Kaspa Pool. K1Pool and WoolyPooly are the two largest KAS pools by hashrate share as of 2026. At 70 TH/s, the KS7 generates enough hashrate that some advanced miners consider solo mining — though pool mining remains recommended for income consistency.
