It is very possible that DGB is one of the many altcoins that people are buying to try and get out of Cryptsy, since because there is a problem with withdrawing BTC. This is why we are seeing the huge price difference between Cryptsy and the other exchanges. they have to buy a lot (usually >1 million), exchanging BTC for DGB, withdraw them and then quickly sell them off on other exchanges to get back BTC but at a loss.
Easily one of the reasons why we have been witnessing several dumps (between 10-40 millions) happening on Poloniex for the past 1 month. if this is the cause of price going down and had Cryptsy not run into any withdrawal problems, DGB would still be around >70sat.
Anyway, Cryptsy has been in this state for way too long, to the point that i feel like adding it to one of my "Trading Tips" to tell people to stay away from Cryptsy. I was already out of there in Late September 2015.
