Maybe its not officially dead, or maybe its just waiting its time to boost up and build it's name like BTC now when it's time comes. There are lots of coins right now and the competition is really crucial. Every coins needs to survive in order raise more investments and projects and became stable. Because of that competition lots of coin will collapsed and that's the time for Litecoin to make a come back.
i dont see litecoin as dead cause i se some improvement on it then also i see this coin that having a great potential in the near future so better to wait and see and not by judging this coin when you see a little dump on it.
