Ndnh are you on both leaderboard? Congrats, never think you are a sports betting guru, if you like, please share you tips to us, players will be happy to be your referrals. 
I don't think there is any type of luck or expert-ism involved to get ranked on the leaderboard without any risk of losses.
All you need to have is a great investment and strategy to use it
Well they still have the esports cashback (which I love betting on) thats coming soon this month you could make an arb on that one and gain huge roi like the one you did on us open.
Cool, I didn't know. Mind sending me a PM when they post the esports cashback promotion?
