Based on BTC price of $79,949 and current network difficulty as of Aug 28, 2026. Actual results vary.
Verdict
The legendary Antminer S9 versus the modern Bitaxe Supra. Old-school industrial ASIC power versus new-wave open-source solo mining — could not be more different.
The S9 produces vastly more hashrate but is loud, power-hungry, and requires 240V. The Bitaxe Supra is silent, runs on USB power, and embodies the decentralized solo mining ethos. Choose the S9 for raw hashrate or the Supra for the home solo mining experience.

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.
| Bitmain Antminer S9 eight-bin OEM reference | Metric | Bitaxe Supra |
|---|---|---|
| — | Upfront cost (MSRP) | $89 |
| -$1.95 | Daily net profit | -$0.00 |
| -$713 | Net after 1 year | -$89 |
| -$1,425 | Net after 2 years | -$90 |
| -$2,138 | Net after 3 years | -$90 |
| — | 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.

Frequently Asked Questions
Can a Bitaxe Supra compete with an S9 on hashrate?
No. The S9 produces roughly 13.5 TH/s versus the Supra's ~0.6 TH/s. They serve completely different purposes — the S9 is a mining machine, the Supra is a solo mining lottery ticket and decentralization tool.
Which is better for home use?
The Bitaxe Supra, by far. It is silent, draws under 15W, and sits on your desk. The S9 is a 75+ dB industrial machine that requires dedicated infrastructure.
Is there any advantage to the Bitaxe over the S9?
The Bitaxe is silent, portable, open-source, and uses minimal power. It decentralizes Bitcoin mining by enabling anyone to participate without industrial equipment.
