I believe that this sudden rise of Litecoin is a pump and dump, with the goal to pump it has high as possible in the next three days, and them let it drop to around $100 level. Why? because Litecoin Cash fork scheduled for Feb 17th. At the moment of the fork, whoever is holding Litecoin in their Litecoin core wallet will receive 10 to 1 Litecoin-cash coins. So, I see this as a maneuver of some (well played) to increase Litecoin holdings. I'm glad for you if you are riding this wave. Be careful, as always, of buying when the is above 70.
I expect Litecoin to get dumped like trash this Sunday, And when it hits bottom you will see a massive re-buy wave (people increasing their coin amount).
