Litecoin is considered as the silver to bitcoin's gold and has massive potential in the future. The coin currently has a market captial of $5 billion and can cross the $400 marl easily by the end of 2018. The coin has been accepted by Coinbase, which has increased its market capital a lot.
In the future, the coin with its blockchain of 2.5 minutes will make transactions much more speedier and secure. Segwit activation has helped a lot with that. It is a good coin and one can expect good returns from it.
I also believe on litecoin and many other coins that have good potentials. Litecoin is one of the most used coin online and this will surely noticed sooner than later.
Litecoin is often used to send in a fast way other than bitcoin. because the fee is not large and also fast. will become bitcoin competitors later on
