Bitcoin's not a waste of energy at all. Think about it. How much power do you think every single bank facility and banking-related office building in the world uses up each day?
I'd wager if you were to see a direct comparison between the total daily power consumption of Bitcoin's PoW and the average daily power consumption of, say, Goldman Sachs... you would then find the statement "Bitcoin's PoW is a waste of energy" completely laughable.
Argument that if one shit requires a lot of electricity then Bitcoin is not a waste of energy is quite... illogical.
no it's really not in this case. I am directly comparing the power consumption of one method of financial bookkeeping (the banking system), with another method (bitcoin). In this comparison, bitcoin clearly is the far more power-efficient way to go.
Do you need to be reminded of how many different, competing bank companies there are? and that EACH of them separately uses up about as much, or more power than the global Bitcoin PoW system uses each day? There's not even room for argument, Bitcoin is far greener than any other alternative we have at the moment.
