I dont know if i would buy litecoin to be honest, I thought it was kind of dead as well due to it not really being needed because of bitcoin. I know you could argue it the other way round since it came after bitcoin.
I just thought maybe theres a darkhorse out their that hasnt been given enough hype for people to buy into, kind of like ethereum before it kicked off. I had ample oportunitys to buy into it at really low prices but never bit, maybe the altcoin world is just going a bit stagnant for now.
LiteCoin is one of the best alternatives, but to be honest all the alternative cryptocurrencies are dead compared to Bitcoin. Bitcoin is the only legit cryptocurrency (with SOME alternatives such as LTC , PeerCoin perhaps, because they are stable and have decent prices for an altcoin).
