BTC actually has a purpose unlike many many other software products that are just pure waste and net loss to society (FB).

  Yeah, it's purposefully wasting energy. Facebook is only incidentally wasting energy as a side effect.

    Perhaps you should compare the usefulness of bitcoin versus Facebook when you consider the energy usage of both, intentional or otherwise.

      I find both useless.

        Unlucky I guess. I would hazard a guess you find crypto overall to be useless. https://www.mastercard.com/news/perspectives/2021/why-mastercard-is-bringing-crypto-onto-our-network https://www.mastercard.com/news/perspectives/2021/why-master...

          >I would hazard a guess you find crypto overall to be useless. No, I quite like cryptography.

            The context is clearly cryptocurrency here, not cryptography :).

  I don't disagree that FB is mostly a waste (the chat and photo/video sharing are probably useful to some people) but on the other hand BTC has absolutely no utility. They are just computing arbitrary hashes and the result of this computation is useless to anybody.
