I saw that video too and while I have great respect for Linus I believe (my own opinion) he was a bit downplaying the impact miners are having. Not to say the other factors aren’t contributing, but think carefully about 2018, it’s the same story except worse. Check out some of the YouTube video on the little home grown diy setups with 30+ cards running. Then think about what people with a little organization, connections and money are doing. Slightly off topic but there’s a small northern country whose bitcoin mining operations consume more electricity than the rest of its country’s consumption combined. That truly shocked me and illustrates the scale at which some of these operations are running.
