It does not have anything special, in fact, litecoin is only attractive because it is like the "silver" version of bitcoin, and that is why everybody is buying them in bulk, because they think that it can reach or at least, have the same price that bitcoin has at the moment.
I have some litecoins at the moment, i bought them at $30 on July, it was incredible.
I bet all my funds in that probably no one knew that the price of each ltc was going to reach $100 during this year.
Probably it is one of the best altcoins of this year.. It was less than $6 on January.
Lucky you, also you're wrong by saying "litecoin is only attractive because it is like the "silver" version of bitcoin"
Litecoin is the second oldest and most robust cryptos. Age is very important in cryptos, like in banks. It proves reliability.
Litecoin is faster than BTC, and BCH, thus if speed is a factor as BCH folks claim, LTC wins over BCH.
Litecoin has 4x capacity of BTC.
Litecoin has very low fees.
Litecoin is nimble in development. It implements new and well tested tech readily.
Litecoin will be part of the second layer LN revolution together with BTC.
Litecoin is pretty well known and accepted next to BTC, and ETH in most places, if more than BTC is accepted.
Still not really sure if i want to just in it right now. Lots of people look scared of that dip, im fresh in this crypto world, so might wait and see what happens
