True. 0% is always desired.
The thing I don't get is, if you kept BTC in your local laptop offline and tried to pay out, it asks "0.0005 transactions fees". And there is no guarantee that BTCGuild will process it, so might end up in a pool that charges. So does a transaction cost by default for all trades at the moment?
Triple mining does 1% fees with weekly jackpots of 1.5 BTC. You can join my mini pool if you'd like, all the info is in m sig.
