Electricity costs, equipment maintenance, etc. are quite large costs, if the results of small mining even lose.
Miners are looking for a low cost mining solution, they install mining equipment in cold places and install savers to reduce electricity consumption.
Absolutely. In mining, electricity and equipment maintenance are the largest cost components, significantly impacting profitability. If the mining scale is still small or crypto asset prices are falling, the resulting yields can sometimes be insufficient to cover operational costs, potentially leading to losses. Therefore, many miners seek ways to minimize operational costs as much as possible.
