Will you bet on fixed games if you get the tip early?
The very essence of gambling in the first place is to win and maximize profits from your wins, so for every opportunity the game avails, it's mostly expected you use it judiciously as it doesn't come often because the casino will not pardon you either if you loose on any bet they don't make refunds rather they take it's as their own profit made from your bet which you placed.
In essence I'm saying if I am faced with such opportunity my straight answer is a big yes I will make good use of the opportunity and stake as much as I can afford to lose just if it later turns against me, because there are occasions the casino has taken from me not minding how I will feel so if I see such opportunity to stake on a fixed game I will stake and win
In other sense I don't see you staking on a fixed game tip you received early before the game commenced as been bad, rather I see it as an opportunity because the intention of the people who gave you the tip is for you to win so why should you denied yourself of the opportunity to win because you feel it's not right. To add, I don't think it's not right because that can't be seen as cheating or stealing.
You've hit on a universal human motivation: the drive to increase one's financial gain and seize every available chance. However, we must always keep firmly in mind that casinos, not we players, are the primary beneficiaries of gambling's inherent profit-seeking nature. You are correct; casinos do not provide refunds for money lost. The house has a built-in advantage that guarantees long-term financial success. Betting on a rigged game may feel like you're even the odds, but keep in mind that the world is a murky place.
If you know what you're doing, you're being financially responsible by just betting what you can afford to lose. However, the ethical considerations cannot be ignored. Engaging in set games affects the fairness and integrity of gaming, and may lead to more severe penalties in the future, even if not seen as cheating or stealing by everybody.
