While home-based mining is possible, professional mining setups generally generate higher returns due to their ability to use industrial-grade equipment. Most high-performance miners require industrial voltage (380-480V) and specialized cooling systems, which are challenging to implement in a typical home environment. However, some smaller miners like the Bitaxe Gamma 601 are designed for home use, though they offer significantly lower profitability.
