The claim that bitcoins consume more electricity than several developed countries has become as popular on the internet as the cryptocurrency itself. Approximately 3,600 new bitcoins are created daily through a complex process called "mining", which consists in awarding a bitcoin to computers that process complex mathematical equations through specialized software. A popular formula for calculating energy consumption is that of the Digiconomist cryptocurrency blog, which is based on the performance specifications of the most used technology for mining. As a starting point it takes all the income from mining, estimates the operational costs of the miners as a percentage of their income and converts them into expenditure for energy consumption based on the average prices of electricity.

This methodology yields an annual electricity consumption for the production of bitcoins that is currently equivalent to 32.56 kilowatts per hour (TWh), while Eurostat figures show that in 2015 Denmark consumed 30.7 TWh of electricity and the Republic of Ireland 25.07 TWh.

You could say that if it is true, it consumes extreme energy, but this is an exaggeration ... The above information is a summary that I have found of additional information, but the problem is to generalize so much when in fact less than 30% are the ones that are In charge of mining, most prefer trading.
