Goldshell SC-BOX II: Siacoin mining and BTCB2 compatibility
Goldshell SC-BOX II is listed for Siacoin (SC) mining using BLAKE2b-Sia hardware. Select the exact condition and variant before ordering.
| Mode / network | Rated hashrate | Rated power | Basis |
|---|---|---|---|
| Siacoin (SC) | 1.9 TH/s | 400 W | Existing store nominal rating; not a BTCB2 measurement |
Can Goldshell SC-BOX II mine BTCB2?
AlphaPool business status: PASS — OWNER_CONFIRMED. This applies to the related Goldshell SC model set, including this exact SC-BOX II listing, based on BT-Miners ownership confirmation. Independent firmware and accepted-share evidence: PARTIAL. An exact firmware archive and an independent accepted-share, credited-reward and payout record were not verified in this review. This does not prove compatibility with any other pool. BTCB2 is the independent Bitcoin BLAKE2b chain; it is neither SHA-256 Bitcoin (BTC) nor Siacoin (SC).
No BT-Miners hardware test is claimed. Network connection, accepted shares, pool reward credit and a completed payout are four separate checks. Confirm the exact firmware, work mode and pool protocol on one unit before expanding.
What should I check before buying?
Confirm the selected unit’s electrical input, circuit capacity, wall power, ventilation, condition and firmware. Store ratings do not establish BTCB2 earnings. Use a wallet explicitly supporting this chain and keep its setup separate from BTC and SC.
Are the displayed earnings BTCB2 income?
BTCB2 estimate unavailable. No reliable BTCB2 valuation and end-to-end mining data were verified for this listing. Do not interpret a Siacoin, Handshake or rental estimate as BTCB2 revenue. Check the calculator’s selected coin, data time, fees and electricity assumptions; profitability and payback are not guaranteed.

Goldshell SC-BOX II: exact-model BTCB2 evidence status
Model identity: this page covers Goldshell SC-BOX II; the current Siacoin-mode listing shows 1.9 TH/s and 400 W. Goldshell SC-BOX product page.
AlphaPool business status: PASS — OWNER_CONFIRMED, confirmed by BT-Miners ownership for the related Goldshell SC model set. Independent evidence status: PARTIAL because an exact firmware archive and independent accepted-share/payout record were not verified in this review. This status does not prove compatibility with any other pool. Matching BLAKE2b alone is not compatibility evidence.
Checked: October 12, 2026 against the owner-confirmed compatibility ledger and the exact product listing. Test one exact unit and firmware, then verify connection, authorized worker, accepted shares, credited rewards and payout separately before scaling.

How to estimate profitability
Profitability is an estimate, not a guarantee. Recalculate with the exact hashrate and wall power of the selected unit, current network difficulty and reward, coin price, pool fee, uptime, electricity rate, cooling and hosting costs, taxes and other operating costs. Record the input values and calculation time; do not treat a calculator result as a promised return or payback period.

Goldshell SC-BOX II overview
Siacoin ASIC. 1.9 TH/s at 400 W nominal; confirm the selected batch and mode. BTCB2 / AlphaPool: PASS — OWNER_CONFIRMED for the related Goldshell SC model set. Independent exact-firmware and accepted-share evidence remains PARTIAL; this does not establish support on other pools. Check the evidence and test sequence. Income currency: For Sia mode, read revenue as a Siacoin (SC) estimate, not BTCB2 earnings. BTCB2 estimate unavailable. Verify the selected coin and operating mode before comparing costs.
Comparison with SC-Box
When comparing the Goldshell SC-Box with the SC-Box II, there are several notable differences. In terms of performance, the SC-Box II has a significant advantage in computing power, with its default mode reaching 1.9TH/s (±5%) compared to the SC-Box’s 900GH/s (±5%), even its low-power mode at 1.45TH/s (±5%) still outperforms the SC-Box. However, this higher performance comes with higher power consumption, with the SC-Box II’s default mode consuming 400W (±5%) and low-power mode 260W (±5%) versus the SC-Box’s 200W (±5%). Physically, the SC-Box II is slightly larger and heavier, but both have a similar low noise level of ≤35dB. Functionally, both use the Blake2b algorithm, with the SC-Box mining Siacoin and SC Prime and the SC-Box II mainly focusing on Siacoin. The SC-Box II has an advanced management system providing more detailed operational data and a new cooling technology for better stability during long-term use, while the SC-Box has a newly-upgraded management software. Overall, the SC-Box II offers more powerful performance and advanced features, but at the cost of higher power consumption and a slightly larger size, while the SC-Box is a more compact and lower-power option with relatively lower computing power.

FAQs
-
What Is The Lifespan Of This Mining Machine?
The lifespan of mining hardware is influenced by usage intensity, environmental factors like temperature, humidity, and dust. Proper maintenance and optimal conditions can significantly extend its longevity.
-
How Does Electricity Cost Impact Profitability?
Electricity costs play a crucial role in mining profitability, as high rates can quickly offset profit. Therefore, it is vital to access local electricity costs to determine if mining is viable. With high electricity costs and high liquidity of digital assets, investing in an energy-efficient miner becomes even more important.
