Keep calm, and Hodl.  Remember that the most recent darling of the crypto world, ETH, had a flat price 6 months in.  Now everyone can't get enough of it.  You can't declare a project dead just because it didn't go up like a rocket from the very beginning.  Coins that do that don't seem to last that long anyway.  HODL will have its time if you have the patience.  And if you have no patience, Hodl for a year and the patience comes built in (along with some nice interest).
