There are serious environmental concerns being raised about the amount of electricity being used to mine Bitcoin (see, e.g.: https://news.ycombinator.com/item?id=27135776). My comment does assume that less electricity use is good, because that's the context in which Ethereum posted this.

I'm mining crypto (very small amounts) as I as I type this, so I'm definitely not going to make the case that all crypto mining is an immoral waste of electricity. But I remain very interested in transition to a PoS system, so as to reduce the strain of crypto on the environment.

All human economic activity that uses electricity should be judged by the same standard then. I think the unstated premise of most of these arguments is that crypto provides no meaningful economic benefit to society, and thus the use of real resources (that sometimes produces pollution as a byproduct, depending on the source) is immoral.
