There is no real use case other than as a meme, it is used as a pump dump coin from whales. painful enough, but even $1 is a pretty tough number to doge. Unless they make a breakthrough and get Doge into a great use case I'm sure there might be some hope, but at the moment it's almost impossible to break that number.
Even if they get a usecase, why would someone use dogecoin instead of other cryptocurrency? I know I wouldn't because a currency that contains the word DOGE and has a shiba dog as a logo does not inspire me trust.
I believe we are talking about Dogecoin today because of Elon Musk. Not for use case and the community, I also observed that the coin has very few longterm holders. Some even think the whales are dumping the token for the last time, I dont doubt that. Elon musk in one of his tweets make a mockery of the coin and the funny response of the market.
