Is Bitcoin a wasteful use of energy?
Of course not! Every system has financial and ecological costs, but how many systems are measuring practical ROI?
People focus on Bitcoin’s consumption, but not Visa’s, for example. Have you considered what Bitcoin can create per kilowatt compared to what the centralized economy can do with the same kilowatt? All systems have consumption which is repurposed in the attempt to create extra value so that efficiencies can be sold to the world in order to make profit. But the real question should be if there’s more profit to be made by using Bitcoin as a tool for efficiency rather than other existing solutions.
