Point to a real production cryptocurrency using proof-of-stake right now. All the big ones are still using PoW and we're what, over a decade in to the history of cryptocurrency?
Once even one of the major chains is on Proof of Stake or Proof of Space or something we can talk about how associating cryptocurrency with PoW is unfair. AFAIK the closest we've come is that Ethereum people started experimenting with proof of stake in December? Things like that are progress but don't do anything to put a dent into the massive electricity and resource squeezes being created by cryptocurrencies.
