I am a strong supporter of Litecoin. And currently it can be explained very simple why Litecoin is still worth (and will be worth).
You want to do a transaction now:
1. Ethereum - I don't think so, network has been clogged since crypto kitties and so, and even now it is not stable
2. Bitcoin - transaction fees are a killer, even the Bitcoin conference itself stopped Bitcoin transactions
So it is simple, at least I use only LTC for transactions for the time being. It is widely accepted almost everywhere, so it is not a problem to exchange it for the coin of choice after the transaction is done.
