The recent extreme price rise is worrisome and it is very obvious that trade volume has decreased so as the post above has pointed out it btc needs to be spent. On the other hand, I don't think "hoarders" will sink the ship so to speak so I really would not worry about it too much. Does anybody not save up currency? Of any kind? You have to spend it here and there but the goal is to save it up... spend a little to get some more...
