I saw this strategy online for guaranteed profit from online gambling.
Since it is well known that gambling is a sure way to lose money, there must be something wrong with this strategy, but I cannot see it at first glance.
The strategy is:
Find an event that can only have two outcomes, for example a football game.
Then bet the same amount on both sides.
You are guaranteed a profit no matter who wins!
Maybe I don't get it but you aren't guaranteed a profit but rather break even if there is no vig?
