Profitability Comparison
iBeLink BM-K1
iBeLink BM-S3 Siacoin Miner
Based on BTC price of $76,908 and current network difficulty as of May 18, 2026. Actual results vary.
Verdict
Weighing six performance factors, the iBeLink BM-S3 Siacoin Miner comes out ahead — it takes 4 of 6 (hashrate, home mining score, noise level, price-performance). Where it pulls away hardest is 258% more hashrate (5.3 vs 19.0 TH/s). That said, the iBeLink BM-K1 isn't beaten everywhere — it still wins efficiency and power consumption. 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 BM-S3 Siacoin Miner sit on each measurable spec:
- iBeLink BM-S3 Siacoin Miner 258% more hashrate (5.3 vs 19.0 TH/s)
- iBeLink BM-K1 73% better power draw (835 vs 3,100 W)

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 BM-S3 Siacoin Miner |
|---|---|---|
| $9,855 | Upfront cost (MSRP) | $1,330 |
| -$1.82 | Daily net profit | -$6.77 |
| -$10,518 | Net after 1 year | -$3,800 |
| -$11,181 | Net after 2 years | -$6,270 |
| -$11,844 | Net after 3 years | -$8,740 |
| 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.
