Start a Giveaway and maybe you would get more people interested again instead of hoarding, maybe NovaExchange can work something out with the Espers Dev's to have Espers as a usable token on their exchange for Lotto, Dice, Double or Nothing, etc a bit like DOT on Cryptopia, could bring good things.
with a giveaway ESP just would end up with a bunch of dumpers.
Besides ESP has already made 2 earlier Giveaways. What ESP need is a good marketing and promotion campaign.
