That's for the thought of the dollar using more energy. The composition of the dollar is proprietary composition of different plants and maybe cotton Is in it if you look it up you will not find the exact formula for the "paper" bills. It is not available for obvious reasons. It makes sense the doge coin maybe more efficient than "paper bills"
PEOPLE, this is not about going green or saving energy just because a car maker is trying to promote his electric car. This is about control of your money and what you do with it. Governments everywhere could care less about saving power. They want control. Plain and Simple. You people following Elon are sheep. Headed right to the slaughterhouse.
