I have been observing this for the last few days and never brought it up on purpose. I cannot think of a single reason why this is going on. There could have been some Bitfinex explanation, but it was always Mintpal leading it and come to think of it didn't DRK/USD market open today in Craptsy?
Either way this thing needs to correct itself.
Its definitely got something to do with Litecoin as we have been tracking against their price for a while now. Dont see why we should be. Possibly once the market realises Litecoin is a dead horse we will shoot back up very quickly.
