Profitability Comparison
iBeLink BM-K1
iBeLink DSM7T
Based on BTC price of $77,929 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Run the numbers across every spec and the iBeLink BM-K1 edges it: 3 of 4 factors go its way (efficiency, power consumption, home mining score). The standout gap is 60% better power draw (835 vs 2,100 W) in the iBeLink BM-K1's favour. The iBeLink DSM7T holds the edge in hashrate. The right pick still depends on your power cost and noise tolerance — the breakdowns above make that call concrete.
Spec Deltas
Stripped to the numbers, this is how far apart the iBeLink BM-K1 and iBeLink DSM7T sit on each measurable spec:
- iBeLink DSM7T 32% more hashrate (5.3 vs 7.0 TH/s)
- iBeLink BM-K1 60% better power draw (835 vs 2,100 W)
- iBeLink BM-K1 47% better efficiency (158 vs 300 J/TH)
- iBeLink BM-K1 58% better weight (6,600 vs 15,600 kg)

Cost & ROI Over Time
Hardware cost is only half the story — here is how each miner's upfront price plays out against cumulative profit at a $0.10/kWh rate.
| iBeLink BM-K1 | Metric | iBeLink DSM7T |
|---|---|---|
| $9,855 | Upfront cost (MSRP) | — |
| -$1.81 | Daily net profit | -$4.79 |
| -$10,517 | Net after 1 year | -$1,748 |
| -$11,179 | Net after 2 years | -$3,496 |
| -$11,841 | Net after 3 years | -$5,244 |
| Does not pay back at current rates (negative daily profit) | Payback period | — |
Projections assume continuous operation, a flat $0.10/kWh rate, and no hardware degradation, pool fees, or BTC price change. Real-world ROI varies.
