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.
I seem to agree. Winter is here and the bear season may last the whole 2019.
It's good that we have LiteCoin as a backup to Bitcoin but more platform coins with better techs are coming out.
