Profitability Comparison
Antminer K7
Antminer S19 Pro+ Hyd
Based on BTC price of $79,032 and current network difficulty as of May 15, 2026. Actual results vary.
Verdict
Run the numbers across every spec and the Antminer S19 Pro+ Hyd edges it: 5 of 6 factors go its way (efficiency, hashrate, home mining score, noise level, price-performance). Where it pulls away hardest is 212% more hashrate (63.5 vs 198.0 TH/s). That said, the Antminer K7 isn't beaten everywhere — it still wins power consumption. The right pick still depends on your power cost and noise tolerance — the breakdowns above make that call concrete.

Cost & ROI Over Time
Sticker price versus what the miner actually earns back: the table below projects cumulative net profit at a $0.10/kWh electricity rate.
| Antminer K7 | Metric | Antminer S19 Pro+ Hyd |
|---|---|---|
| $3,500 | Upfront cost (MSRP) | $6,000 |
| -$5.08 | Daily net profit | -$5.87 |
| -$5,355 | Net after 1 year | -$8,141 |
| -$7,210 | Net after 2 years | -$10,283 |
| -$9,065 | Net after 3 years | -$12,424 |
| Does not pay back at current rates (negative daily profit) | Payback period | Does not pay back at current rates (negative daily profit) |
Projections assume continuous operation, a flat $0.10/kWh rate, and no hardware degradation, pool fees, or BTC price change. Real-world ROI varies.
