Elon Musk is an entrepreneur, what he tells or does is meant to help his business grow and not promote others. He meant nothing with his tweet, it was a troll.
I am sure he is not Satoshi 😀
Yet he made Paypal (and Tesla, SpaceX, Boring, yadda)... But jokes aside, i wonder if that mysterious tweet was some sort of tip. He is the opposite of McAfee, few words and lots of action.
Anyway we have been expecting a "bull" of sorts before the halving, if nothing because of the simple expectancy of it.
And he is certainly not clueless about Bitcoin. Hopefully he has some stashed without telling anyone. The moderator can't take the joke about painting the bitcoin (
BTC) logo in one of SpaceX rockets, but you will see.
