I'm giving nicehash a shot with my 5 AntMiner S2's. I've only been on an hour but getting about a 5% reject rate. Also, I should be having 5TH but it's seems to only show about 4.3ish...
Is that a normal reject rate? Most on there seem to have less than 1%. I'm using Westhash because I'm in the USA.
Sometimes it depends on what coin they are mining, some coins gives higher reject then others. I suggest you to find a bitcoin pool instead....
