SealMiner — frequently asked
How does SealMiner compare to Antminer / WhatsMiner?
On the A2 PRO line the efficiency is competitive with the latest S21 and M63 generations, especially in hydro.
Is it good for small farms?
SealMiner is industrial-focused. For very small setups, Antminer or Avalon home models are usually a better fit.
