That’s a rude way to say “thanks for clarifying, I agree with you.”
“doesn’t scale” usually refers to technical difficulty with throughput. If you meant that Bitcoin et al cause massive environmental damage, you sure didn’t say it clearly.
I suggest that you would get a lot of mileage out of improving your writing skills first before trying to flame people. As it is, you’re just playing yourself.
You probably didn't even read my comment. Because it wasn't about whether PoW or PoS is more efficient.
