Mining Profitability in 2026
To calculate exact daily, weekly, and monthly revenue for the Bitmain Antminer KS5 Pro, use our live Kaspa mining calculator. Enter 21 TH/s as your hashrate and 3,150 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 (~$5,500) in the hardware cost field of the calculator to see your estimated days-to-break-even based on current network conditions.
Pros & Cons
Pros
- Highest kHeavyHash hashrate in the Bitmain KS lineup (21 TH/s)
- Kaspa's 1-second block time provides smooth, frequent rewards
- Best-in-class KAS efficiency vs competing ASICs
Cons
- High acquisition cost ($5,000–$6,500 new)
- 3,150 W draw requires dedicated industrial electrical infrastructure
- Kaspa-only hardware — no algorithm switching fallback
Frequently Asked Questions
Is the Antminer KS5 Pro profitable in 2026?
At $0.05+ per KAS and electricity below $0.07/kWh, the KS5 Pro generates meaningful daily profit. Kaspa's fast 1-second blocks create very smooth reward curves, making income more predictable than slower-block coins. Use our live Kaspa mining calculator with 21 TH/s and 3,150 W for current profitability estimates.
Can I mine coins other than Kaspa with the KS5 Pro?
No. The KS5 Pro is an application-specific miner hard-coded for the kHeavyHash algorithm used exclusively by Kaspa. It cannot mine Bitcoin, Ethereum Classic, or any other coin. If KAS price declines significantly, this hardware has no fallback algorithm — factor this single-asset risk into your purchase decision.
How does the KS5 Pro compare to the IceRiver KS5L?
The IceRiver KS5L offers 20 TH/s at 3,400 W (170 W/TH) versus the KS5 Pro's 21 TH/s at 3,150 W (150 W/TH). The KS5 Pro is more efficient by ~12%. If both are available at proportional prices, the KS5 Pro is the better choice on a per-TH basis. Compare current market prices and apply them to our KAS calculator to see the ROI difference.
What is kHeavyHash?
kHeavyHash is the proof-of-work algorithm used by Kaspa. It is a variant of the HeavyHash algorithm designed to be compute-intensive with moderate memory requirements, making it efficient to implement in ASIC silicon. Kaspa launched in late 2021 as a GPU-minable network, but dedicated ASICs became available in 2023–2024 and now dominate the network hashrate.
