to me, Litecoin is just a tool for me to transfer money from exchange to wallet with cheaper fee. Besides, I don't see it making any contribution to our lives. The withdraw fee for Litecoin is very cheap, so in the past people used it a lot, it has a simple algorithm and is not as fussy as XRP.
Maybe that is why it has such great value, or possibly followed by the great whales always supporting it.
I only use Litecoin because the coin's transaction fees are very cheap and used a lot in transactions. One more thing, Litecoin's value is very low and I can be sure LTC will hit $100 soon by the end of the year if market conditions are good. Of course, there are still many things you need to consider but overall Litecoin is still a good choice for investors.
