I like this realist, skeptical, Machiavellian perspective.
Is it a money game, or is there something more to it? https://bitcointreasuries.org/ is a site I use to try to determine if this is a legitimate trend or not. At $1.5B, Tesla's initial position is 1.31x the original position of MicroStrategy, which was the previous largest position for a public company. Granted, MicroStrategy's position has since appreciated to about $3B, so Tesla is about half that in terms of current market value.
It seems Tesla's position is serious, not just a token. But I suggest everyone try to look at the data and make up their own mind.
I'd be surprised if this turns out to be more than a celebrity endorsement pump and dump.
