in my perspective it is not right to say LITECOIN is "dead" otherwise we can say it is sinking and going to be lower in value... but as of now there are still many miners of litecoin. i dont think about the dev if there are still update to it...
I think the price difference between the bitcoin and litecoin will be more in the future.
There are only a few coins that are able to battle with bitcoin.
I don't see any surprise in that if the difference in value between ltc and btc widens in future as the price in insanely increasing which ltc isn't and even if ltc increases, the % of increment are not the same. Ltc us not necessarily dead or sinking. We mistaken this by comparing with btc value which is wrong.
Litecoin is the coin, for safe and sure btc storage. Most use this when they dont know what to do or invest they put coin in lite cuz coin is stable they wont lose much or gain much. This is something that is good for some people cuz they search for stability but rest are just here when they see rise opportunity for easy money.
