Those are good points, and don't worry it didn't really come across as dismissive of the environmental damage.

I do know most of the newer cryptocurrencies are much less destructive that Bitcoin, but they're all still like, thousands of times worse than just, Visa.

You're also right to notice that there are all these mother fucking billionaires peddling crypto and NFTs and shit. They will absolutely keep it afloat longer, but from what I've read they can't keep it going forever. It's still ultimately a pure speculative asset that has no underlying value other than the ponzi scheme itself.
