Newbie, mining RVN on HiveOS, No payouts yet.

I'm averaging 13-16 mh/s on single RX 570 on HiveOS. Have been mining for about 18 hours and no sign that any thing has accumulated for a possible payout in the future. Getting message that "have never found any blocks. Sad!" . Is this normal? Btw, using Minermore with Team redminer on Hive.
