seems like someone pulled his buywalls
Maybe. I still see plenty on the bid side on Cryptsy though. This looks like a normal correction to me. I mean the price just did over 2x in the last month.

right. nevertheless i don't like the artificial touch this rise had driven by huge buy walls by a single person. smells a little like manipulation if you ask me. buy walls weren't touched and everytime the price got near those walls they were pulled and set a little lower.
There are walls on Cryptsy DRKBTC just off the visible chart at 0.01,
Finex DRKBTC &
DRKUSD, also as of yesterday on
BTer DRKCYN
You don't like them which is fine, plenty of people do though and if the price retraces to 0.01 then they will not be pulled or moved down what ever the volume, I'd consider that a healthy correction after the last few weeks of rises and especially the jump up from 0.008 to 0.016
Anyway they are what they are so you may as well accept that or move away if you can't, as it's unlikely that you can do much about it apart from whinging.
