First watch this vid.
https://www.youtube.com/watch?v=3LSBZtL_sLsCrypto is incentivising people to destroy the planet.
At the moment the world is focused on getting rid of plastic, I'd say crypto is what we need to get rid of next.
If your crypto isn't green it's going to be taken out and shot. If your favourite coins don't destroy the plane they might have a future.
You sounded more philosophical if you ask me because taking what you type here literally would mean someone who is not communicating anything but beyond that I guess you talking about environment impact of crypto but that should not be a concern at all. Crypto does not use a special form of energy. If today, we no longer on plants or dams to power our houses, and we using something else so also would mining use such energy nothing more or less than that. So other thing can kill crypto but not based on your theory.
