I am a newbie and have am delighted I chose this pool for my 17.5 ish TH/s.
I just noted a kind odd thing, has anyone noticed that the last 15 payouts were paid with the same price for bitcoins? ($1212.03 USD).
Yes, I am trying to learn and do keep a spreadsheet of my data/payouts, etc.
Up until these last 15 payouts, the prices was always different, reflecting the current bitcoin price at the time of the payout, this "anomaly" just caught my detailed oriented eye.
Anyway, Mine On!!! (I still need a few more months to realize my ROI and become mostly profitable).
I'm not sure exactly what the question is

But the BTC/$ price is certainly considered random

If you are referring to your BTC reward, well that of course will also appear somewhat random due to pool luck vs pool hash rate vs your hash rate.
Haha, that's funny! Last 15 were payed with the same price for Bitcoin??? How is that? You get payed certain amount of BTC, it is up to you how much you sell it for.
