I think Dogecoin is a very strong project and the main point is that a Alon musk support of this project so they show that it will be a successful project in future.
According to my experience is that one the market situation is good so the project definitely achieve their goals.
Even if Elon wouldn't support it, Doge will rise. Doge hash rate is even rising more and more because more people are getting into it than investments they can't afford. It's one of the most googled coins.
The success of Doge can be compared to the success of LTC. Although they may not really rise high like thousands in just a decade like BTC, they are going the long game.
