Elon singlehandedly crashing BTC right now. Isn't the reason stated is nonsense anyway?
It seems pretty disingenuous that he has just come to this^ supposed realization now--right after he has made huge waves with his Bitcoin investments and doge coin pump. If memory serves he has been in trouble with the sec for his potentially illegal comments regarding Tesla on Twitter as well.
Interestingly, Tesla is in a unique position to take advantage of crypto mining(this was pointed out on a YouTube channel guy who is a silver bug) with their solar and battery technology, not to mention their access to raw materials where they could potentially own the mining silicon and manufacture profits with free electricity.
