Cryptsy was one of my first crypto-exchanges, I stopped using it months ago because it was too slow. Anyway, I have seen reliability problems in virtually any exchange and I hope Cryptsy have solved its issues.

What I have observed is that any coin has its own reference market in one particular exchange. I don't know why, may reflect big investors' preferences or simply people are attracted by the volume/depth of the market making it larger. In my opinion, Whitecoin has lost its reference market when Mintpal was closed. Now I'm trying to figure out how many investors are trapped in Mintpal and which exchange will host the main WC/BTC market.

I'm trying to be diplomatic but Mintpal shutdown is a real pain in the ass
