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.
That's why I said wherever possible. To be honest though, any coins that only trade on cryptsy are of very limited interest for the average profit-seeking miner. If you can't subsequently move the btc that you trade them for....
Has this already escalated to all btc withdrawals?
I have never had problems with withdrawals there, both BTC or altcoin.
Anyway about WTM solution.
I wanted to expose exchanges filtering, turns out it wont be as easy as I have expected.
Need to redo some part of the coding that handles rates caching to be done on the fly.
