A very good take on Elon from a Redditor, explaining his psychology:
"I think it’s more than a game to him though, I think he’s trying to find his next buck. He knows the Tesla narrative is super risky, he knows SpaceX is very expensive, and he knows that if things go south he could be in a lot of trouble. So, he dabbled in crypto.
Cryptos are unregulated and worth something and he knew it could help Tesla, but he got more than he bargained for. He knew the pump would work but the increase in BTC was TSLA like. So, being the narcissist that he is, and just like every prior company he was in, he felt like he should own it and be considered a founder. Who else could do what he did! One problem: it’s too late to be a founder of Bitcoin.
But what if he showed that Bitcoin was trash and that he had something better? In comes Doge. Now he’s savior Elon, just like how he’s the savior of tesla.. and one day people can consider him the founder. Hence his “working with the devs”. What if “the devs” don’t listen? (Read: that narrative doesn’t work?). He already gave the answer on Twitter: his own crypto. Yeah it would be a pain as he put it, but such is the life of being a hero right?
So Elon’s own coin becomes just like all his prior endeavors: he gets to skirt the law and claim others work with ridiculous claims to deliver a product that people still genuinely like and corp America doesn’t want to offer and make ridiculous profit. Even better, not only is he skirting the law but there really isn’t any law at all. And on top of that, the value he creates is literally open ended and undefined. Let me put it this way: why go through sleepless nights trying to make the model 3 which, let’s face it, has competition coming and will be hard to ever scale… when you can make a crypto do some tweets and get the same hundreds of billions?
So yeah I think it’s still about the money. And yes he likes to f around for sure. But I think this is more than that."
