The company is into the production and design of high-end 28nm/16nm/7nm working chips and provides developments/assistance in fields such as blockchain technology, cloud computing, and artificial intelligence.

The Whatsminer M21s mines with the SHA-256 algorithm can produce up to 40 coins, but the top coins are Bitcoin(BTC) and Bitcoin Cash(BCH). With an average hash rate of 54Th/s, it uses 3200W-3500W of power.

The board is an Ethernet interface, TF card slot, IP button, reset button, and status indicator on the control. But the most impressive is the fact that the MAC address is attached to the control board for convenience when looking for the device's IP address. This feature aligns with Whatsminer’s pledge to produce miners that are easy to use for everyone.
