litecoin in my opinion is a pretty good coin after ethereum
there are coins that are literally good after etherium . as for now the ranking goes like this : btc , eth , xrp , bch and last should be ltc . i could say that ltc is good after bch .
Talking about the price for 2019 I think it's quite potential,
I personally feel the price of Litecoin will be pretty good in early 2020 so I think investing in Litecoin can now be profitable.
rumors said that there will be a halving by this year for litecoin . having is said that it can up the price of cryptos . so your right , investing on ltc now can be profitable because others will also buy ltc in preparation for the halving .
