When Did You Start Mining RVN?

I was sort of late to the party starting 3-15-18. I had not done any mining prior; the learning curve and preparation took me awhile to understand. I knew about RVN in January 2018 but through dithering and lack of knowledge it took me a bit longer than most to get started. Since then I have been mining without interruption with between 2-14 cards, now I am back to four or five.

When did you start?
