Think of it this way, how much effort do you think any tech company is going to put into creating a serious use case for Dogecoin, or Bitcoin, or Ethereum? There are multiple answers to this simply because there are multiple crypto currencies. We're literally ON a use case for Steem right now. It doesn't matter in the time period of a day, a week, or even a month if Dogecoin grows a few percent more than Bitcoin. What matters is adoption, and I just don't see Dogecoin making it long-term.
