What problem is it solving for people? Especially people who are going to disproportionately suffer the impact of climate change (ie poor people)?

* Escaping inflationary fiat currencies * Avoiding capital controls * Avoiding financial censorship * Not growing poor slowly

That's great news... so how do I opt-out of the CO₂ that BTC is generating?

How do I opt-out of the CO₂ exhaled by the 7 billion other humans on the planet, or the CO₂ from Facebook or TikTok data centers (as IMHO both are very harmful for the planet)?

Same way?

What a non sequitur.

The claim being put forth is that crypto's environmental cost FAR outweighs its utility.

Your counterargument is that such concerns are unraisable simply because one can avoid personally using BTC. Or to put another way "if WE destroy the environment it's none of YOUR business"

And that is wrong -- the atmosphere is shared by all. Changes to its composition are everybody's shared concern.

If you want to argue that some other business's activity are too damaging to the environment to be allowed to continue... fine, make those arguments. But don't bat away concerns about crypto's absurd environmental cost as "none of your darn business"

Whatahoutism doesn’t make Bitcoin useful.

Bitcoin is a force multiplier for ransomware.

Unpatched vulnerabilities, Network Access Brokers and Ransomware as a Service are all force multipliers too.

"Money is a force multiplier for crime".

Are the consequences of the massive energy usage also opt-in?

If this person had 1 BTC, I suddenly think they would not find it so useless. I think they would find a use for it rather quickly.
