Nah, I will still do the same. If the price is too low to pay in order to gain that much profit, in my mind it's obviously a scam. I don't know what you think about this, but for me this is what comes to my mind. So no. I won't take the bet. And it's not based on any current situation or decision-making flaw. If you take this opportunity, then you are just greedy and making decisions based on your emotions.
You're going to assume scam even in the purely hypothetical scenario??
So if the winnings are EV+ but are too small - you're not going to take it because it's not worth it, but if there are too high - it must be a scam. Fine, not judging. Is there any optimal stake/chance/winnings ratio of a one-time opportunity, or do would you reject anything by default?
