I remember hearing someone at a pasta night event talking about how bitcoin algorithm stuff is wasting computing power and how he didn't think that was ecological or sustainable.
you should have asked him how sustainable gold mining is
Why'd you brought it up then? Fiat is unsustainable, as it's based on blind faith and backed by servile obedience. Isn't arguing for something you're agnostic/ignorant about, unwise?
i'm not for or against gold: truth is there is no stopping its mining. we'll go to outer space to get it. i'm pointing out that the argument that bitcoin is anti-ecological is naive.
yes, bitcoin mining burns energy (less than fiat though). this is what makes it secure and what makes it money. those wishing for a eco-light alternative don't understand the system.
