I think we have to accept that this may be DRK's settled price range - at least as far as the market against bitcoin is concerned.
It will be only when big sell and buy walls support that price range... say 1000 BTC buy on 0.0075 and another 1000 sell on 0.0085 so that it finds equilibrium in 0.008.
With no walls, the price can move wildly with off-the-book buying and selling of large quantities. If one wants to buy 10k DRK for example, what's the settled price of DRK?
