And one year after Lite Coin is still standing even still gathering discussion although not leaving to expectation, but because its still being talked about is a development in the direction there are several coins that have come after LTC and no where to be found today. So I believe, there is still a future as we still have exchange site listing it while some gambling site still accepts it...
I guess you are right. If Litecoin remains tradeable at exchanges, and useful among gambling sites, then there should be nothing to worry about. Also, I have seen that Litecoin has implemented the SegWit scalable solution into its codebase, so it should be a matter of time before it gets approved by the miners, making LTC faster than ever before.
One of the many things that I have admired about Litecoin is that transaction confirmation times are much faster, than Bitcoin. But other than that, it lacks constant development and innovation, in my own opinion.
Nevertheless, I hope that LTC would remain widely used among users, making it grow as time goes by. Just my opinion.
