As long as we’re still burning fossil fuels to create electricity anywhere on earth, wasting any kind of energy is bad.

So your saying that if I use solar power to power a lightbulb that then I forget to turn off, that’s bad?

It doesn’t add any value to anything. It’s expensive (in terms of energy cost) and absolutely, 100% useless.

Uh actually it is not useless, no idea where you got that, there’s tons of things you can buy with it. Other than drugs (which alone provide a use case, but il continue anyway), you can pay for protonmail, buy computer and other stuff. and theres a few lists (https://monerica/ .com/ is one) with a bunch of more stuff you can do with it. (I’m not endorsing anything here, just saying it exists)

crypto just facilitates more trade over the internet, thats how its useful
