About this miner : 

In April 2020, MicroBT, one of the leading crypto mining hardware companies, released the MicroBT Whatsminer M30s, the first in its M30 series. It was clear MicroBT meant business this time, as shown in the improvements from the older M20s version and the wide acclaim that followed the release. MicroBT has quickly built a reputation for being one of the leading equipment providers in the space, with a commitment to transparency and reliability .

They're the necessary backbone of Bitcoin, and their products should be any farm's first choice. The MicroBT M30s is an ASIC mining hardware machine, which works with the SHA-256 algorithm. The Whatsminer M30s can mine top coins like Bitcoin(BTC), Bitcoin Cash(BCH), but it's also able to mine coins like TerraCoin(TRC) and Unbreakable(UNB), to mention a few. The M30S was one of the first miners to boast the beginnings of the 3x joules per Terahash generation .
