Been mining Slush for 10 days or so and my confirmed goes to say $2.34 (I have it set in US money) then down to $2.14 then goes back up a few cents I have been off and on tweaking my Bitmain U3's and have had ZOMBIES,,and other such errors as I learned about hotstarts,,,driver issues ect....
Am I fined for my sudden flucuations in Hash Rates.?
No, it does not matter if your hashrate is 10gh within a given hour and 100gh in the next. I'm pretty sure that in a daily thing, you're just being hit by the obligatory payout variance. Look at the dashboard you will see last day luck, etc.
One day the pool simply find X block, on a worse day, the pool find less than X block, hence variance.
