Litecoin is a very good cryptocurrency. It's fast, secure and has a lot of fans. The capitalization is big which makes it very interesting to buy for a long term. Since it is a serious currency, I think the speculation will not touch it very much. The creators are a very good team, well known developers.
The price is too high for short term traders, because it's almost in its all time high price. This is a better chart to look at, don't let coinmarketcap chart confuse you :
So don't listen to those who keep telling you to buy litecoin right now, it may go down also, it's the market. Of course it may go up as well, but if you are risking all the money you have, I don't advise you to buy it. For long term traders it's good, because they don't really care about that and they know that most coins are cheap now. I believe in the future of the cryptocurrency world. It still has good perspectives.
As always, the money is yours and you do with it whatever you want, I am just sharing my opinion !
