With Bitcoin looking at a soft or hard fork in the next few weeks I can see Litecoin shooting towards $70. It is already moving up the market but at the same time there are other things going on in the background beyond the Bitcoin forking.
There is also the fact that Charlie lee the creator of Litecoin has returned full-time and left his role at Coinbase. So that he can concentrate on the development of Litecoin.
Add to that the interest from Ben Davenport (Chief Technical Officer) at Kraken who is also taking a major interest and looking to support Litecoin these factors are showing some promising signs of growth for Litecoin.
Beyond that it has close links to Bitcoin being on the same Segregated Witness along with Litecoin currently being faster and cheaper I can see it being a good investment short and long-term.
