Everybody knows that Dogecoin was created as a joke, but now it is worth real money. Do you think it is real to earn on it or it's all a big bubble?
It's still a joke even it's worth real money. As long as it has trading volume, there are people who will trade it.
But to hold DOGE because of its fundamentals? I doubt the majority thinks of it that way. They are trading that joke coin because it's good for short-term trades and easy to manipulate. With just one action to make it hype again, the DOGE market reacts right away. That's the risky part of trading that coin.
