I think Litecoin would die in the next few years if there is no innovation at all. The only thing that Litecoin is good for is trading and holding it for long term. In the end, Bitcoin will stay for plenty of years to come. Just my opinion. 
That is my main concern for litecoin. There is no active development at all. We do not need bitcoin No2. In terms of innovation, lite coin is inferior to Monero, Ethereum and Dash. The user base has shrunk a lot since the introduction of ASIC. I used to mine litecoin, not any more.
