So when the bitcoin halving occurred it seemed logical to me that my payout to the miners would have decreased by 50%.
However my payments decreased by roughly 3.5 times
The payout before the halving was 0.00111840, so I was expecting my new payouts to be about 0.00055920.
However I got paid 0.00032694 yesturday and 0.00032072 today.
It seems to me that genesis-mining is using the halving as an excuse to scrap off additional coins that should be paid out.
Did you include the maintenance fee in your calculations? The mining revenue decreases by 50%, but the income will be reduced by more than 50% after fee.
