hmm so basically for every BTC 144 pounds of carbon dioxide are created (1kwH creates about a pound on average)?! why is it necessary to waste so much energy and create such a huge carbon footprint?
It's not a waste. It's a price for having decentralized cryptocurrency. Also, I don't get why a huge carbon dioxide footprint would be bad. Plants require carbon dioxide to conduct photosynthesis. More CO2 - more plants growth. Are you against nature?
