Imagine someone comes and wins 100 btc and wagered 1000. Like some have done, you would get 1 btc from that (maybe 2 if you have the boosted one) and you would have to pay the whale 5 btc. Would that be fun for you to have to pay that whale or lose your trust rating on this forum?
Maybe use a more realistic % next time.
Also it clearly says 500% of commission on the title and that could mean anything. Is it 500% of the commission you get? Or is it 500% of the original commission? Make things clear for people.
I agree with acidyo, this can be easily unfortunate for you...
