Please consider dropping cryptsy exchange rates wherever possible. The spread between cryptsy prices and other exchanges is a bit of a bad joke, because everyone is using whatever altcoin they can to get their coins out. It's a bit like using the mt gox btc rate just before they went pop, and it severely distorts any profitability calculations.
Indeed I have noticed this, didnt connect the dots though with recent cryptsy problems.
The problem is that so many coins are *only* listed on cryptsy from supported exchanges.
Removing cryptsy would remove so many coins from the list.
I will try to add all missing exchanges today and see how it looks.
