ok so there is pooled mining.. i have that tab open.. so is it better to pool mine or solo?
is cpu mining worth it if i have a gpu rig? or does the hashrate from cpu mining pale in comparison?
what is "GRC address" do i leave that blank?
Why don't you read the first post? There's a lot of information about the coin and also tutorials how to mine. I think this is the most profitable coin there is available and sure use all your cpu:s:
https://cryptocointalk.com/topic/1922-cpu-mining-tutorialtopic/The idea is that you calculate boinc with cpu and get paid grc (max 150grc/day/pc). Very profitable. You can also solo mine and 3MH would get you quite a good amount of coins per day. Also pool mining is possible it's up to you.
