What we are waiting for? Elon's tweets? I don' think it will bring big impact on Doge price anymore. If we only rely on Elon Musk, I think it won't be safe for the reason of invesing in Dogecoin. It is not 2021, we are already in 2025. People already know well about the connection between Elon Musk and Dogecoin. There is nothing massive there, Elon Musk is only playing around with Dogecoin. I personally have no longer intention to invest in Dogecoin.

I agree with your POV as before it was a big deal for investors that a big celebrity with huge money is investing and promoting a token and many people thought that this is something huge as Elon is backing this project and it won't rug pull etc. etc These thoughts were really there in past and if we revisit them now it feels like they have no value now.
As you already said currently the adoption is so high that people might not be speculating on Doge and Elon's tweet anymore but still even in the recent events whenever Elon posted something about Doge it pumped which is proof that people might be speculating still, as many meme coin hunters follow Elon and if they don't then they make a big mistake.
Well, the point is Doge still has great potential but yeah investing in BTC on someone's suggestion is not a good idea we should do our own research, I if have some money I would do DCA in Doge as I expect it to hit $1 at least. I can be wrong so NFA.
