To buy an Antminer S9 in China, head directly to wholesale market stalls in Shenzhen’s Huaqiangbei or Guangzhou’s Shiqiao areas. These spots offer immediate hands-on inspection and negotiation on spot stock. For the freshest units and lowest prices, visit physical stalls to check the device’s fabric—the aluminum casing texture—and the stitching of the hash board’s soldering. Soudangkou aggregates verified stall listings to help you find reputable sellers.
Where to Find Antminer S9 Spot Stock
Shenzhen’s Huaqiangbei is the epicenter for mining hardware. Stalls here often have hundreds of used or refurbished S9 units in stock. In Guangzhou, the Shiqiao wholesale market also offers competitive pricing. The key is to avoid intermediaries—buying from a stall means you can touch and test the unit before paying.
Inspecting Physical Quality
Check the aluminum casing for dents and corrosion—a smooth, clean surface indicates careful handling. Examine the stitching on the hash board’s soldering points; even, shiny solder joints suggest quality refurbishing. Ask the stall owner to power on the unit and run a hash test. Most stalls have a test rig ready.
Negotiation Tactics
Start by asking the price per unit for buying 10+ pieces. Stalls often have tiered pricing: single unit prices are higher. Bargain hard, but be respectful. Mention that you’re comparing with other stalls nearby. Pay attention to the power cord and fans—genuine Bitmain fans have a specific sticker and sound.
