To be honest I doubt Elon Musk will mention much about cryptocurrency give the US Presidential Election is underway. Think about it, he is willing to commit $45m per month to an election candidate (Donald Trump). The last thing on his mind right now is pumping doge coin. Despite his jokes with doge coin though, I do believe he holds a lot of Bitcoin. He believes in the technology, but now is not the time he will be pushing it to the media.
Elon Musk is an opportunist. He's only into crypto to make a lot of money. Not because he truly believes in it. Now that Musk announced his full support for President Trump, he hopes to obtain the crypto industry's attention. After all, Trump presented himself as a pro-crypto candidate.
We can only imagine Elon's companies rising all the way to glory during a second Trump term (and a bullish crypto market). Perhaps, even DOGE will benefit from this. Who cares about what Elon Musk does? Crypto doesn't need him to survive. As long as it stays decentralized, there should be nothing to worry about.

But he has a lot of money already. So his motivation for getting into it is not for any sort of financial gain from it.
He did agree to donate $45 million a month to the Trump campaign last week.
Now his profile picture has changed to laser eyes to make fun of when Biden did it:
There is also a coin already called ELON MUSK HAS LASER EYES DARKELON worth $0.01usd.
