Litecoin has the power of Bitcoin & DOGE combined. It is deflationary with fixed supply like Bitcoin. Again, it's transaction fees are cheap and has a quick settlement time like DOGE. There is no reason for it's untimely death.

Only drawback I see in Litecoin is that it's community is not as apprehensive to new projects as Bitcoin/DOGE. Openness to the new & untested is required for growth.
