How Does Electricity Cost Impact Profitability?
Electricity costs play a crucial role in mining profitability, as high rates can quickly offset profit. Therefore, it is vital to access local electricity costs to determine if mining is viable. With high electricity costs and high liquidity of digital assets, investing in an energy-efficient miner becomes even more important.
