If you were told the outcome of a soccer match, hours before the match was scheduled, and you were assured that it would 100% win, how much would you be willing to bet on it? Assuming it was a 100% can’t lose situation.
This is a lie and not possible, no one can tell you it's 100% guaranteed, if they do so, they wanted to scam you, deceive you or attract you to their website for gambling or gambling prediction odds, betting in gambling involves taking risk and no bidy will take that risk on your behalf except they want to deceive you.
Assuming you had millions of dollars that you could put on the match, where would you place the bets? Bookies often limit players. How could one successfully place millions of dollars in bets without drawing up suspicions or having their money frozen? Just curious.
One has to be careful because how will they know that you have such amount of money at hand to bet with, they will also persuade you to bet the entire money into gambling because they said it's hundred percent sure, that's a pure way to express scam, only risk gambling with the amount you can afford to loose, your account can definitely be frozen if you're using a KYC casino, which means they can cease such huge amount or reported you to AML agencies.
