I don't think it has anything to do with energy or the environment. I think Elon Musk distancing himself from Bitcoin is a consequence of the recent spat of highly publicized ransomware attacks using bitcoin. Elon Musk is connected to the military-industrial complex; it is plausible the federal government has given him forewarning of an impending war on crypto currencies, to make sure their asset, the guy who launches lots of their satellites, doesn't get caught in the crossfire.

This is pure speculation of course.

Yeah, this is more plausible. I think it’s multiple factors simultaneously including the bad PR from the environmental footprint. And it’s kind of funny because Musk has never been a full throated promoter of cryptocurrency ever. Social media is full of people pumping crypto and yet Musk has regularly made technically-accurate skeptical comments about bitcoin or similar cryptocurrency.

I think the Colonial attack has made many people think about cryptocurrencies and the potential for more regulation given the publicity and impact to society. There is no need for him to get any special "tip" to make that determination, or at least have it part of the mosaic of information he uses to evaluate cryptocurrencies.
