Mining for a few hours – nothing received

Hi,

I wanted to try mining on my RX5700XT, I setup Teamredminer and let it run for 5-6 hours. According to what I read on the Internet, you should have 1 Ravencoin every 1/2 hour.

I still haven't received anything in my Raven Core wallet. I was mining with the Cruxpool.

I see the minimum threshold for Cruxpool is 50 RVN.

– Does this mean I have to mine 50 RVN before I get a payment to my wallet?

– Does this mean that the 5/6 hours that I mined for Cruxpool have gone to waste? Or is there an invisible balance on Cruxpools side which will grant me my coins eventually? I feel like this setup is kind of a scam to make people mine for free. If someone mines 49 RVN and he turns off his rig for maintenance for example, he gets nothing and the pool keeps the 49 coins.

Thanks in advance for your clarification.
