The electricity is used to verify transactions, which has a massive added value many times exceeding the cost of the electricity invested. Calling this a waste of electricity is the same as calling the hundreds of thousands (if not more than a million) of employess of central banks, regulation authorities, payment processors, etc waste of air. Really really naive and childish. P.S. Did anyone ever calculate the carbon footprint of all these people whose jobs are going to be taken over and compared it? I haven't done the approximation/calculation, but I am pretty sure that cryptocurrencies are going to be a massive improvement over the current system in that aspect as well.
