There is nothing wrong with using energy. Do you live in a dark cave and eat raw vegetables?
Users of electricity are not polluting. The polluters are the generators of electricity. If electricity generators switched to solar or wind, you would have nothing to complain about.
Yes! and it's not like coal is the only source of energy anyway. A lot already use alternative and renewable energy to provide electricity to people.
To OP, why don't you criticize the resource usage of the banking system? they pollute more than Bitcoin, weak security, and has extremely high fees. It's like doubles or more the resource usage of Bitcoin.
Everytime u trade btc u are basically killing a few chipmunks (or equivalent weight of other animal/s).
Yeah, whenever you use a fiat currency, you are basically killing an entire habitat along with the animals in it.
