So I have run into the problem before with Cryptsy. I have determined that they are holding coins and putting higher conformation times on coins they want to. It seems they will put a higher conformation time on coins such as Doge to push the coin down and then release them into the market when they are not as profitable. This is why I no longer trade with them. This has also been reported by alot of other users. Also they put limits on how many coins you must have before you before you can trade. This seems to be a trait of Cryptsy. I would look at trading with another exchange.
Agreed. I have had this problem with Doge and Infinite coin on their exchange when I was pool mining and transferring large amount of coins from my wallet to my cryptsy. Their support line all but verified this was the case as well. Some BS about "keeping the market value and market amount fair and balanced" which really meant doing whatever they wanted. I do not trade there anymore.
