Yep forget about depositing ANY coin at cryptsy when the market for that coin gets busy
QRK, DOGE, LTC are the worst, but really any market that gets a price spike will immediately result in deposits taking forever to arrive..... some say this is to help build the spike and stop people dumping. I believe this to be the case myself. However if it really is true this is market manipulation and should not be tolerated.
You will be lucky to see your doge there in 20 hours time if the price spike continues..... with slowing down deposits the prices rises and builds frenzy, good for an exchange the holds bags of doge themselves ..... then time for them to sell then just after that release all of the deposits..... watch price tumble as people who have been waiting hours all hit the sell button. Mostly i hear the same thing, just as the price crashes or just after your deposit will show up.
