Doge coin deserves it because it's a old crypto coin now, I think as old as BTC if I'm correct, what I would like to share is everyone should remember that doge coin is a meme coin, there is no utility or use cases to this project and it's impossible to add one now so be smart and know what you are doing
Did you just say an old coin with zero utility deserves to be listed on Coinbase pro? That really sounds contradicting 
I would give Doge more credit because it has its own blockchain, you can mine it, and gambling platforms accepts it. There are so many jurassic coins tha haven't made it to bigger exchanges.
