You are right. To be precise, we can say that Dogecoin is just a meme coin. If we currently expect big profits on Dogecoin, it won't happen again. Dogecoin is only famous for the figure of Elon and does not rule out Elon will also feel tired of all these scenarios.
Dogecoin has been famous for a long time before Elon Musk knew it, because in the past many people used Dogecoin for certain things even though the price was very cheap, because whether or not a coin is famous is not only seen from the side of the price spike, but also must be seen from in terms of age and durability in the market.
