Has it occurred to you that if you're really that confident you could be making money on bets

It occurred to me that I might be making money from Pringlescan on this issue, if I was willing to bet with him, and if he was willing to bet with me. But I don't even know whether he's a legal adult -- and either way he was too obviously biased in favour of his idea. I arrived at the same conclusion as pedanterrific that it might be unethical to bet with him.
