Battling climate change is already very alarming and I wish that a new way of mining - one that does not consume that much energy would be discovered really soon. I'm concerned as to how humans have been consuming non-renewable energy at such a fast rate when renewable energy is not yet a thing. This should be given more attention given the effects that this would bring and the possible aftermath if we do not resort to more environment friendly options.
For the bitcoin to be your own bank, the electricity consumption is worth it. How much power does the world's bank consume every day? Much more than Bitcoin.
