I could be wrong but I personally believe that Elon Musk buying massive amounts of Bitcoin publicly was all theatrics.

It’s the same reason RFK Jr. acts like he’s a democrat and supports leftist organizations.

If he didn’t [they] might try to harm him.

RFKJr makes sense, but I dont care what political affiliation he is he is a great man that has risk everything to save the planet from evil Bill Gates and the cabals vaccine plan to kill of the population.

As for Elon Musk Nana has two main images in my head with him.
One is the satan symbol his baby mama had inked on her large baby bump.
And the other was a statement that VK made a long time back at a time when it seemed Musk moved away from her and into helping the white hats. VK said that how it turned out with Musk depended a great deal on his handlers being able to control him and keep him focused on the white hat side.

what else do you need to know about his interests

Seriously! What else? It's like people want to idol worship Musk even though ALL the evidence suggests that he does not have our interests at heart!
