And that doesn't speak well about the coin because it counterparts and some of them just came new and making wave (trending) in the cryptocurrency space. If a coin is doing well definitely people would talk about it. It I have not heard anything about dogecoin for a long Time.
It can be possible that it is being talked about but just not in the spaces that you don't frequent in. But usually, if a coin grows exponentially, it is everywhere. Dogecoin definitely has not reached that level of growth to be the constant topic of everyone everywhere but I don't think it's doing that bad.
There are so many cryptocurrencies out there that you cannot expect for everyone to be talking about the same thing all the same time.
