Mind you that when you ask about things like this, people who hodl the coin are going to tell you to keep on hodling, at least it helps the coins performance if more and more people are hodling it.

Dogecoin is a meme coin and i noticed that the hype around meme coins is slowly fading away, and they are basically pump and dump coins that can be easily manipulated, even by something as flimsy as a tweet. If you can make ROI in the short term i would advice you sell once you make profit, because there is no use cases that can make meme coins sustainable for the long term.
