I'm looking to source Bitcoin mining equipment for a project we're working on. Ideally, I need details on the specifications, performance metrics, and pricing for your products. It would be great to know about the energy efficiency, hash rates, and any warranty or support options available. Additionally, if you have any recommendations or best sellers in your line that cater to different scales of mining operations, please include that info. We're also interested in lead times for order fulfillment, and any discounts for bulk purchasing would be appreciated as well. Looking forward to your detailed response!
