Hi i mine eth and change them rvn, atm my 24h eth is 0.00138106 and 24h rvn is 24.86467232?

I was thinking i should get more rvn?

Only mining rvn my card whattomine says i can get 27rvn per day so im losing atm.

People says you get more rvn when mining eth and change them rvn but i wont get more that way, why?
