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% cant lose situation.
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.
Then you have to like scatter it across several bookies, but still, this bookies has system to recognized when there is something awry with bets and where it's coming from and where the bets is going.
So in any case if there is really a big suspicions in their end, they might confiscate your winnings and worst, even the money that you put, that big $1 million, might not return to you.
