You have two options, someone give you..
A: The Duel at Dawn bonus worth $15,000
B: or $7,500 straight to your wallet
Well I think it's way logical and smarter to go for a guaranteed cash instead. With the real cash you could very much take a small percentage of it and take some little risks and make a pretty lucky win . But as for the first option you are simply betting on a bias idea that probability sticks on your side.
Even if the second option calls a bigger probable win I don't really fancy it since losses too are inevitable.
