ASIC Manufacturers: Bitmain, MicroBT, Canaan and Other Mining Brands

The ASIC market has several major manufacturers plus many resellers, repair shops and hosting providers. For a miner, a brand is not just a specification number; it also means access to spare parts, firmware and support.

What to compare between brands

Compare devices under the same conditions: actual hashrate, wall power, energy efficiency, temperature, noise, warranty and delivery time. Nameplate values may be measured in different operating modes.

Also check whether service is available in your region, whether hashboards, fans and power supplies can be sourced, and whether the firmware is tied to a closed ecosystem.

Bitmain — one of the largest manufacturers of SHA-256 and other ASICs
MicroBT — known for its WhatsMiner line
Canaan — manufacturer of the Avalon series
for Equihash, model and service availability may be more limited

A reseller and a manufacturer are not the same

A marketplace listing may come from an official partner, broker, hosting company or private seller. Before paying, verify the serial number, condition, warranty terms, customs charges, contents and return policy.

The used ASIC market can make sense, but the discount should compensate for the risk of worn fans, hashboards and power supplies.
