MicroBT

MicroBT Whatsminer Bitcoin miners stand as the most established alternative to Bitmain at industrial scale, with the M-series consistently competing on efficiency at the high end of the SHA-256 market.

The M60 launched the current generation at 170 TH/s and 19.9 J/TH, with the M60S stepping up to 186 TH/s at a leaner 18.5 J/TH. For buyers prioritizing maximum efficiency, the M60S++ pushes to 226 TH/s while actually improving efficiency further, to 15.9 J/TH among the most efficient air-cooled SHA-256 miners on the market. At the top of the lineup, the hydro-cooled M66 delivers 250+ TH/s, built for operators with existing liquid-cooling infrastructure who want to push density and performance further than air cooling allows.

Every Whatsminer model targets the SHA-256 algorithm for Bitcoin mining, backed by MicroBT’s standard factory warranty. Whether you’re running a single unit or scaling a farm, the M-series offers a genuine, well-documented alternative when Bitmain stock is limited or when specific efficiency numbers matter most to your electricity cost.
