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.
The last thing that you don't want to happen to your account is getting frozen with millions on it if you are in Drake-like status and you are a high roller betting you can escape getting your account tagged, but if you are thousand dollar bettors and you usually bet earlier and never a last minute bettor, they will question your motives.
So bet within your betting range if you have accounts on many sports bookies then spread your bet to avoid suspicion, casinos will trigger an alarm for any usual bets this is something high rollers and old gamblers know, they can proceed at their own risk, but the risk is too high.
