i believe it's not dead yet. the doge community is active and doing good since a few years ago. then elon musk came and made a high impact for doge price. i think the doge community can handle it even if elon musk is gone.
I think you overestimate Elon's current influence on DOGE. His words don't worth much now and until he makes it as a payment method on Twitter or something like that DOGE won't see a big pump.
I don't think there are changes in the price even if Elon do something on his memecoins to pump. We are in a bear market and if Elon try to pump doge then you know what most investors would do if there's a pump. His influence has nothing to do with what is happening in his memecoins, it's just that we are in the bear market and every coins in the market are suffering from losses.
And I don't think doge would be out of the market if they have Elon Musk as influencer of this coin. Things might change a little if Elon would do something but remember that almost every altcoins would follow the trend of Bitcoin.
