I'm sorry. I don't think you're too stupid.
It's just that at this point, "Bitcoin is a waste of electricity" comes across as trollish behavior. We've all seen that a million times. It's been explained a million times why that arguably isn't the case. So either engage with the actual argument people are having, or don't say anything.
Saying "bitcoin is a waste of electricity" doesn't contribute to the conversation at all anymore. It's the exact equivalent of posting a comment that says "boo bitcoin" or "bitcoin sucks."
So yeah, if you say that, I'm going to poke at you. And then I'm going to give you the actual argument, in case you haven't seen it. As I did.
