What's the best intensity to set for ccminer cuda9. How can I reduce the rejected shares. The rejected shares is around 75% at the moment.
What GPU are you using? I have mine set to 17 - 18 (I have a 1080 Ti), not much hashrate lost from 21. Also try adding --submit-stale, it could help (well at least in my experience). Also I think your ping to pool server matters too. They say <300ms is recommended.

From which block will the MN payment be activated?
If I understand it correctly it's at block 5000 when full rewards are activated. 60 coins go to miners and 60 coins go to MNs.
