Dogecoin is a coin meme that was popularized by Elon Musk at that time, so the price of Dogecoin could grow or rise very significantly, just because Elon Musk made a similar post on twitter recently.

But I can't imagine how people can equate dogecoin with bitcoin, even though the two have very far differences, too many people even call the two have something in common, what is the reference so that they can be equated, I don't know the exact reason from the people who mention that.
