I also see the move as a hedge against Bitcoin's "bubble fears" and network issues. As more people flood into BTC, it might get more unstable, and Litecoin is likely a also safer mid-term storage while the futures markets are being established. Litecoin is "supposed" to be 10% of Bitcoin, so it might also be market sentiment starting to level that price discrepancy relative to it's Golden handcuff. It's due for a pump in general from vloggers spreading their "picks" for 2018.
