I see some resemblance on what you are saying, but with cryptocurrency and bitcoin they are the center of attention themselves, what i mean is that news are created around them with companies and governments accepting them or banning them or using them as a payment method, and the price change and the popularity are what actually affect these news, and the news themselves along side the users influence the price so it is a cycle, so crypto and bitcoin don't need news from outside its own environment to stay alive.
