People stopped using fax because it's inconvenient, slow and shitty quality.

You'll be shocked to know that as a dev, I had to fax Apple several documents a decade ago just to publish in the App Store. They had zero facility to accept it via the internet. Not a joke. Fax from the UK to USA.

same with my bank in the UK when I had to apply for a mortgage, what a pain was to find a service or working fax machine it was

Sounds like bitcoin and its countless variants.

If your organization cares about its carbon footprint it won't use airplanes. If your organization cares about its carbon footprint it won't use cars.

Why not take this argument all the way?

You appear to be attempting hyperbole, but this is actually a serious concern for lots of charities.

Mozilla already promised to do that. https://blog.mozilla.org/en/mozilla/mozillas-climate-commitm...

The mentioned examples don't have reasonable alternatives in many scenarios.

Fax usage is growing every year though: https://finance.yahoo.com/news/fax-services-market-revenue-e.... I'm not sure about the carbon footprint of fax, but I think it can't be worse than sending paper through slow mail.

More than 95% of cryptocurrencies are not energy sensitive. This is very misinformed. When people think cryptocurrencies they think Bitcoin which is rapidly falling in market share.

95% is kind of misleading as there are so many shitcoins. I would be more concerned about the energy profile of the TOP X coins by market cap.

From top 10 blockchains by market cap eight are not energy sensitive. Ethereum will stop proof of work this year. So it will only leave Bitcoin to be the carbon monster.

Also, by the usage and transaction volume Bitcoin is already behind Ethereum and others, so it is no longer even top 1 and has been falling against others for the last 4 years.

They aren't wasteful because they are hardly used.

95% of 10 k. Coins. 66% still buys mainly Bitcoin

Ethereum alone transfers 35B daily vs. Bitcoin 20B daily, so this statement is absolutely false and Bitcoin is not even number one in the usage.

Ethereum is PoW too at least until some undetermined moment in future.

Is that true? I don't doubt you, just haven't seen any numbers pointing towards that being true is all. If you have some resources I can check out, I'd be very grateful.

In terms of "Total Market Capitalization", Bitcoin currently sits around ~39%[1], which feels unlikely if "66% still buys mainly Bitcoin". But again, you could be right.

I got it from a research per US holder: https://finance.yahoo.com/news/half-us-bitcoin-holders-got-1...

Which assumes both that everyone owning Bitcoin are from the US and that everyone using Bitcoin self-report their ownership.

I can ensure you the number looks very different in reality.

Your assurance, as a cryptocurrency advocate, has less than zero value.

Way more than 95% of the 8900 cryptocurrencies are jokes, like CumRocket.
