Whatsminer ASIC mining

Whatsminer Models

Whatsminer, manufactured by MicroBT, is the second-largest ASIC miner producer in the world and Bitmain's closest competitor in the SHA-256 Bitcoin mining space. Whatsminer machines are widely used by industrial-scale miners and hosting facilities for their strong hashrate-to-power efficiency and reliable hardware design.

About MicroBT

MicroBT (officially Shenzhen MicroBT Electronics Technology Co., Ltd.) is a Shenzhen, China-based semiconductor and mining-hardware company founded in 2016 by Dr. Zuoxing Yang, a former chip designer at Bitmain. Despite starting several years after Bitmain, MicroBT grew rapidly to become the clear number-two producer of Bitcoin ASIC miners worldwide, and its Whatsminer brand is now a direct, high-volume alternative to Bitmain's Antminer line in essentially every market segment — air-cooled, hydro-cooled, and immersion-ready machines alike.

Company History and Market Position

MicroBT entered the ASIC market with the original Whatsminer M-series and steadily closed the efficiency gap with Bitmain through successive generations (M20 → M30 → M50 → M60 → M70). Each generation has typically matched or slightly undercut the equivalent Antminer generation on joules-per-terahash efficiency at launch, which is why many of the world's largest industrial mining operations and hosting providers deliberately run mixed fleets of Bitmain and MicroBT hardware — both to compare performance and to avoid depending on a single supplier for spare parts, firmware updates, and future allocation during supply shortages.

In 2025, MicroBT expanded its direct-to-customer presence by launching an official US WhatsMiner online store with dedicated service centers and tax-free storage facilities on both coasts, a sign of the brand's growing footprint outside of China and its push to compete more directly with Bitmain's retail and hosting partnerships in Western markets.

Official MicroBT / Whatsminer Resources

Always buy directly from MicroBT's official store or an authorized reseller — the second-hand and grey-market ASIC trade has a well-documented problem with counterfeit units and look-alike domains impersonating official MicroBT sites.
