He always tweeting about dogecoin nonstop maybe testing his influence? but if he already did that for months doesn't that means he's just trying to hype up dogecoin and increase the demand somehow?
Honestly the one who knows whether he's just shilling or not is elon himself but considering that he's already a billionaire I think he just doing it out of trolling or to relieve stress it's like a dang game after all.
What he does can't be just ignored, he makes another story anyway in the crypto world. He is supporting it now and supposedly we are happy, everyone has their benefits for what he did.
