Not many people want this coin,the buy side has been low compared to other coins for months.
The coin is great,maybe people fear that the main selling points of DRK is also it's weakness because of the Bitlicence proposal that is comming,regulation does not want complete  anonymous transaction,i think big investors stay away from this coin because they are afraid that they will loose money if the outcome of the proposal is negatif about the complete anonymous transaction aspect of digital currency and that some aspects will be useless anyway.

Also if you look at the chart from Darkcoin you can see a big spike and then a large downfall,people will think the coin is a pump and dump coin,they stay away.

i highly believe it's aslo better for this coin to ditch the Dark part in the name of this coin and name it Privacycoin,the name is more soft and you do not think strait away to a coin thats being used only by people that want to buy drugs,guns and other criminal things and do not want to be tracked.
Also if we and the team are doing marketing for this coin it's better to promote it like it's you are paying in the same way as cash at the store,realy make it less criminal intended and promote it more positif,also if you are making graphics for promotion dont put a guy with a hoody on and hide is face in the picture like they did on cryptocoinsnews,i was so disapointed they took that route,it's the worst thing you can do to attract big investors or new users to make the afiliation to shady persons that want to hide there criminal behaviour.Just promote it like a person that does not want people to know how much money they spend on a new TV etc.

just my 2 cents for the day.
