Pool fee will be increased to 4%. Due to the current hashrate etc and the fact that with math you should get 4x as much orphans as on btc, i cannot sustain a fee of 3%. Most day's all of the "profit" goes lost into orphan blocks. And this only got worse as the pool grew, up to 4min/block currently. I'm not doing this to "make more money", but to stop the pool from losing money.
Still too low, if you are paying for orphans and invalids, it should be 6% fee. 4% is good only if you are not paying for orphan/invalids.
The pool isn't paying for stales/orphans.
