I'll keep an eye on it to see if the threshold ticks down more. Solo mining I'd probably never find a block. At least the Apollo II is a solid node compared to the Raspberry Pi's. I tried running my Raspberry Pi with Umbrel and Start9 but both would crack out after a couple days.

Thank you for your continued input.

I was thinking about trying ViaBTC because it looks like they have a .0001 BTC payout. Still learning.
