I don't think LTC will die. Silver and gold co-exist. As far as I know, Litecoin is next to Bitcoin. We just need to wait for the developers to do their magic.
We still don't know the Silver on cryptocurrency market is Ethereum or Litecoin or Bitcoin Cash. At now, we have 3 subjects can become to silver after the price of Bitcoin stable. And very difficult for predict one of three coin as my list become to silver.
