FAQ

Find answers to common questions.

How long does shipping take?
In-stock orders ship within 1-3 business days after payment. Pre-sale orders follow customer service notification. Hong Kong delivery usually arrives next day; international orders take 5-15 business days depending on destination.
What payment methods do you accept?
We accept bank transfer (local Hong Kong & international), USDT and major cryptocurrencies, and wire transfer (T/T). Large orders can negotiate L/C terms.
What is the warranty policy?
New miners come with a 12-month standard warranty covering manufacturing defects. Labor is free during warranty; shipping costs are shared. Liquid cooling modifications and physical damage are not covered.

Bitmainoffer.xyz specializes in exclusive channel discounts. Contact our sales team for a custom quote. Bulk orders (10+ units) enjoy additional discounts and priority shipping.
