Whether he still owns Twitter in the future or not, it was not a factor for Dogecoin to die. And I don't think Dogecoin will simply die for that reason.
Remember that we are in bear season, the entire market is suffering a huge price markdown and Dogecoin had not escaped from it. Yet, it was not how we measure if the project is dying or not because I know that this coin will still survive even without Elon Musk's support
But when it comes to Dogecoin, it has a lot to do with Elon Musk, If Elon Musk has resigned from his post. The Dogecoin Army's aspiration that Dogecoin will be used as a means of payment on Twitter can be destroyed, the plan was traded before the purchase of Twitter so that the last two weeks in November many bought dogecoin.
I think most investors will pay attention to this and withdraw their investment funds.
