Yes, right now it's all buyers and few sellers putting pressure on the price. I'm sure much of the current hoarding revolves around the 10% payout for Masternodes. Once that accumulation levels off it will bring the sellers back in and you should see some consolidation. If a shitcoin alt clone like AuroraCoin with zero innovation, a 50% premine and roughly the same coin total as DarkCoin could reach $90 earlier this year, it's certainly possible for DarkCoin to reach it and have a much better chance of staying there IMO.
It's difficult to say where Drk eventually will end up. It could get some anonymous coin/wallet competition, level off around $10-$40ish, or go completely crazy. It's the sort of coin that could get to $300+ one day without a person sounding completely insane for saying so.
So it's a risky coin to sell, unless you really need the money right now. I expect plenty of btc people sold off when the coin hit $10-15 or so, and felt it'd never go any higher.
I just know that unless the price goes really crazy, I'll never feel comfortable selling. I'd like to sell high and buy back in low, but beats me as to when we hit those marks. I should probably spend this weekend looking at how to set up a masternode.... my coins are wasted just sitting there otherwise. Less temptation to sell them too if they are working for me.
