Crypto miners have been invited to join this year’s Earth Hour campaign by turning off some of their hardware between 8:30 and 9:30 pm on March 24. The initiative to take part in the WWF’s annual event comes from the Russian crypto community. The “Crypto Hour” organizers hope to focus attention on the need for eco-friendly blockchain technologies.
