Proof of stake crypto is not great but arguably worth the environmental impact, if proven useful. I'm not convinced it's useful or positive for the society in general but some people enjoy crypto and will claim the oppositive.

The consensus about proof of work crypto is that it's terrible for the environment. I know someone who crypto mine in winter to heat up his home but it's more for fun, and he would rather invest in new windows than cryptominers.
