I may have misunderstood how it works then. I thought that merged mining meant the miners work on both BTC and NMC.
I want my miners to work solely on BTC.
Why?
With BTC only mining if you get X BTC then w/ merged mining you get the same X BTC PLUS some NMC. Even if you threw away the NMC you wouldn't earn any less than a BTC only pool.
It would be like if your boss paid you 10 BTC and 50 NMC per hour. You don't like NMC so you quit and work for a company which pays you 10 BTC per hour. How exactly did you come out ahead?
