Dogecoin has been my favorite alt coin for quite a long time. It serves as a good cryptocurrency for tipping others, as well as being a fun and inexpensive medium of exchange.
However, I'm worried what might happen to Dogecoin in the future, since it has been quite some time that no new version of the QT wallet has been mentioned, neither some innovation to keep it going for the long term.
It would become ideal for Dogecoin to add SegWit to its code, and gain traction if it gains acceptance from the miners. Then, if it manages to become the first cryptocurrency to accept the scalable solution, it could rise in popularity once more (not to mention that transaction will be near instantaneous).
Nevertheless, Dogecoin is a great cryptocurrency being inexpensive and relatively stable, making it a great way to tip others or send micropayments faster than BTC at a fraction of the cost.
Looking forward to your opinion.

Dogecoin has a strong supporting community and well developed network. Its fast and reliable confirmation and cheap tx fee are outstanding among the thousands of alt coins. I can't say if and when its price will go up, but I do believe it'll stay alive. Lips sealed Lips sealed
