Litecoin seems to be the forgotten son, does it's own thing as and when it wants to. Give it time and I am sure we will see it catching up although I did expect a lot more from litecoin after it got lightening.
It is just a part of its development i think because just like other crypto-currency litecoin can make and establish a development and growth in terms of its price , value, transaction in the market. As long as people will continue to chose bitcoin as a part of trading in trading site which can make a movement on its stock on the market and can give a good thing for its development and progress on the market on the future.
