It shouldn't be though, and it's gonna take influential cryptocurrency people wising up fast to divest from btc into those other projects before righteous public sentiment gets used by central banks against all cryptocurrency projects. All of their effort and hype will be entirely in vain if they don't think hard and fast about the real human impacts of what they're investing in.

The cause and effect you describe hasn't applied to significant investors in oil or coal up to this point that I'm aware of, despite the disastrous effect those two revenue sources have had on the environment. I'm not sure why Bitcoin would be significantly different when its negative externalities are effectively invisible and a bunch of the mining occurs in mystery data-centers overseas, outside of the reach of central banks.

Ethereum is used more than bitcoin (measured in transactions per day), so that'd make it more likely to be considered the de facto cryptocurrency, no? It'd also make it more "popular" with cryptocurrency users, though definitely not as well known by the layman.

I'd argue the one that sees the largest "value" of transactions per day.

Ethereum is used as a computer, but it can also be a way to transfer value. So I don't agree on using that as a that metric.

It would seem that Bitcoin is more popular amongst those who don't use cryptocurrencies, and Ethereum is more popular amongst those who are. Just a thought.
