The GP comment falsely implies that PoW is the only kind of cryptocurrency (and, well, the obnoxious and anti-intellectual tone).

There are many reasons to dislike crypto in general, but "it destroys the environment" only applies to PoW-based systems and not crypto in general.

Also, you should read the guidelines: "Please don't comment about the voting on comments. It never does any good, and it makes boring reading."[1]

What percentage of cryptocurrencies usage is not PoW? What are the negative environmental impacts of the other approaches? Being better than PoW doesn’t necessarily mean they stopped being wasteful.

I rephrased that first sentence to remove the reference to HN voting. I was simply remarking how the tone will cause people to object to it quicker regardless of the merit of the underlying thought.

Bitcoin is obviously the top. But Ethereum and Cardano are 2nd/3rd and ETH is moving to PoS while ATA already is. Tether is 3rd and is a stablecoin, so it is PoS or PoW depending on the backing contract.

So quite a bit actually. We are talking hundreds of billions in market cap at least.
