On the 14th June payout I got 0.051 BTC mined with 801 GHS. That was a bit over 0.0072 BTC/day.

Next week I reinvested all my payouts and got an extra 66 GHS.

This week, with 867 GHS, I'm getting 0.006 BTC/day!!!!

I can understand some fluctuation in the payouts, that is the nature of crypto minning, but this is something else... something completely different!

Is this legit? Is this plausible?

Or is it something else?
