For the early miner, the earning was $90 a day.   We gave out 2000 medic coins each day.  One person with a 1080ti got 30% of the pool's points.  So he got 600 medic coins a day.  At 15 cents per medic coin and his 600 medic coins got  $90.  Like everything else, early miners got the rewards because of low difficulty.
