Why are there lots of coins listed on Cryptsy but with no markets to sell them, like ARG, CAP, DGC, GDC, MEC, MNC, NVC, PXC, all of which I have balances of on multipool? What's the point in being able to deposit them with Cryptsy if they can't be traded? Is there anywhere else to sell them, as if not it seems rather pointless mining them?

Coinwarz even quotes it's prices for those coins from Cryptsy but I can't see where it's getting them from.
