There is no argument here, only ranting. I'm not even sure if I agree or disagree with the sentiment. It's so completely devoid of substantive reasoning I can't tell one way or another.
1. Climate change is very bad and should be avoided at all costs.
2. Atmospheric CO2 causes Climate change.
3. Most electricity that is generated, releases CO2 into the atmosphere.
4. Crypto currencies in their current proof of work form, use an excessive amount of electricity.
5. Therefore crypto currencies cause Climate change and should be avoided at all costs.
