In fact, while I own some DRK, I think its a TERRIBLE decision by Finex. (ducks)
Look at the volume on Mintpal. DRK has held those levels for the better part of the last month regardless of price swings. That is rare in the land of altcoins and bitfinex wants a piece. Doesn't seem too off-base to me.
Im betting it's more to do with possible legal attention rather than anything with the actual coin itself.
edit: i was too slow on the post
