About QB Mining: Your Trusted Bitcoin Mining Hardware Partner

Neatly arranged brand-new mining rigs, professional packaging equipment, and quality-inspection stations)

Since the early days of Bitcoin mining, QB Mining has focused on one mission: delivering high-performance, cost-effective mining hardware and reliable support to miners worldwide.

We were born from the real needs of the mining community—we’ve seen new miners struggle with inefficient rigs and non-existent after-sales, and we understand seasoned operators’ pursuit of stable hashrate and cost control. That’s why QB Mining sources only from top manufacturers (like Bitmain and WhatsMiner), conducting 3 rounds of hashrate, power consumption, and runtime tests for every unit. We also run a 7×24 technical support team, covering everything from rig selection advice to on-demand troubleshooting—so you can focus on mining, not headaches.


Our Commitment: "Hashrate + Support" Dual Assurance

  • Rig Quality Assurance: Every unit undergoes strict validation (no refurbished/defective gear) to ensure stable operation right out of the box;
  • Transparent Pricing: Sync with global market rates, no hidden fees—we also offer "coin-specific rig recommendations" (e.g., BTC/ETH-compatible models) tailored to your goals;
  • End-to-End Support: We provide setup guides, hashrate optimization plans, 1-year warranty (extended coverage for core components optional)—turning your hardware investment into consistent returns.
