Can anyone explain me how I managed to get negative profit from placing an order on nicehash with a price of 1.06 BTC/PH/day to zpool showing average profit estimate 0.00148 mBTC/GHs/day ? (sha256, no errors, no rejects)
You lose on nicehash fee.
You lose on payment tx to NH.
24hr estimates are for the previous 24hr with x hashrate; not 24 with X plus your rental.
Many ways to loose on a rental. If t was as easy as you think, machines would be rented 247 by the same people all tihe time earning profit.
I also agree: argon2 is crap. I don't mine it anymore.
its better to be seller in NH than a buyer, renting.
