I don't think Litecoin has a future long-term. It achieves nothing more than Bitcoin.
If the whole market goes up 4x soon, then yeah, LTC will hit $400.
But I don't think the market will make even 2x this year.
You do not understand we should not see litecoin as an innovative coin we should look at it as a backup to bitcoin in case something goes wrong and in the case everything goes right and bitcoin becomes extremely valuable litecoin could become the most circulated of the two coins similar to what happened to gold and silver.
