Yeah, that makes absolutely no sense as a rationale behind Tesla no longer accepting bitcoin. No sense whatsoever--and you're absolutely right, Musk ought to have known all of the facts behind how bitcoin is mined and so forth; he's by no means a stupid person.
Rationale..
We're talking about the guy who after getting finned by the SEC didn't spend too much trolling quietly indoors and came back to Twitter with this:
Now we're having the same reactions a tesla's share owners in that topic, "Dude, what the f* is wrong with you?"
But there is nothing wrong with Musk, it's not a bug it's a feature!!! He simply is this kind of person, and everyone seeing his first comments about crypto years ago when he was trolling with Doge should have been a little cautious on how this guy does things. He is not the usual WS investor, he is sometimes even more dislikeable than Warren, at least that guy is simply stating his beliefs, Musk likes to cover everything in a fog of half-truth half lies.
The moment Tesla published their filling showing they have bought Bitcoin I tough that at least temporarily he will stop with the non-sense as his usual attitude will get him in trouble with the SEC but nope, it didn't work. Right now with all this BTC drama, he will get away even without the slap on the wrist but it come a day when his trolling will lead him into serious troubles.
