Hmmm. Given the fact that the post talks extensively about electricity use for mining in an attempt to justify it, I concluded you didn’t understand what mining was.
As for GPU mining, that hasn’t been cost effective for Bitcoin since 2012 or so. The blow up in GPUs in the last few years is not due to Bitcoin mining.
No the blow up is still related entirely to bitcoin and its ilk. Mining is still going on for the hundreds of OTHER cryptos out there. I know everybody likes to pretend it’s just bitcoin, but it ain’t.
