American scientists compared the cost of electricity for mining and metal mining.
It turned out that it is more expensive to mine cryptocurrency. This was stated by scientists Max Krause and Thabet Tolaymat.
According to the study, which was published in the journal Nature Sustainability journal, mining entails a very large expenditure of energy. For example, the energy consumption of the entire Bitcoin network, according to various estimates, varies from 4-5 TWh per year to 26 – 44 TWh per year and even 46. These figures are comparable to total electricity costs in Hong Kong and Ireland.
