I woke up to a bunch more grayed out "Mined" amounts. These are the ones with the little hammer icons. A couple at midnight, 2am, 3am, 4am, etc. You get the idea. They, along with the first 7 I saw from last night, still say 0 confirmations or, more precisely, "Generated but not accepted mined."
Is there a possibility that the interest payments will, for some reason, not pay as I'm seeing here? In total, 20 "Mined" entries. 19 have 0 confirmations; 1 was paid.
Do I just have to wait a really long time or is something broken?
I got two grayed out minting like you. However most of them confirm. I think it's like orphan problem in mining. All is lost if it happen. You can mitigate your lost by search orphan problem in p2pool. You will understand why. 1. Set your zeitcoin wallet to high priority in window task processing manager setting. ( press control+Alt+Del). 2. tune up you internet connection in your router setting
