US and Canada delivery, included items and support check
- United States: the current BT-Miners policy says international delivery typically takes 5–10 business days by DHL from Shenzhen or Hong Kong, with tracking. Confirm the dispatch warehouse, final shipping charge, import taxes or duties, and delivery estimate for the selected unit before payment.
- Canada: the same international estimate is published, but confirm service to the destination province, carrier, GST/HST and customs responsibility, plug/electrical requirements, and the written delivery estimate before payment. US availability or timing is not evidence of Canadian availability or timing.
- Included items and warranty: confirm the exact PSU, cables, cooling hardware, condition, factory or seller warranty, DOA process and repair path in writing for the selected batch. Do not assume that accessories or warranty terms are identical across variants.

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.
Frequently asked questions
Is this the same as every L9 or L11? No. Hashrate, power, voltage and cooling differ by exact model; use the family links above.
Can it mine LTC and DOGE? The listing identifies Scrypt and the LTC/DOGE family. Verify the selected pool’s exact configuration and merged-mining terms.
Are earnings guaranteed? No. Recalculate with current inputs and operating costs.

(1) The hashrate value, power on wall, and power efficiency on wall are all typical values. The actual hashrate value fluctuates by ±3%, and the actual power on wall and power efficiency on wall fluctuate by ±5%.
(2) Caution: Wrong input voltage may cause server damaged.
(3) The noise is loudest when the fan is under maximum RPM(rotation per minute).
(4) When the server is used at an altitude from 900m to 2000m, the highest operating temperature decreases by 1℃ for every increase of 300m.
