If someone here ask me about my opinion on Litecoin, at the moment, I will say that: Litecoin is a very good altcoins, and should always be considered for our portfolios. However, at the moment, I think that there are so many other better options to invest (only top altcoins) and get better profits. I don't say invest in Litecoin now will not give you profits, but profits if you actually receive might be smaller than what you might get by invest into others top altcoins, like DASH, Bitshares, or Dogecoin. It's my two cents for current situation, but honestly I always keep my eyes on Litecoin to find good chance to invest in LTC.
Some people don't want to risk their Money in high risk altcoins that potentially give more rewards. They prefer to stick with the oldest, largest and most secure networks like bitcoin and litecoin.
Litecoin has always followed bitcoin so when bitcoin was at it's peak back in 2013 trading at $1200 USD, litecoin was $50 USD. When Bitcoin was trading at 20k USD, litecoin was $400 USD so one can speculate that litecoin can be trading at least 50k usd if bitcoin one day reaches 1 million dollars.
