A lot of bettors say “fade the public” like it is already a sure strategy. If many people are betting on one side, they quickly look at the opposite side.
That's the most ridiculous and ludicrous way to gamble. It will be a blind way of betting. Usually, such thought come to some gamblers mind when they have had losing streak and out of frustration, they start looking for different strategies. I know of some gamblers who tried that once or twice but they consistently failed.
But honestly, how do we even know where the public is betting if we don’t check any real data?
You can know this if you bet offline. Like you see gamblers discussing the game they have bet on. By such discussion, more people can sample their opinion and that will give you the insight of public sentiment of a particular game and even the options they are betting on.
Still, it does not mean we should blindly bet the other side. Sometimes the public is right too. But at least if we check the numbers first, we are not just guessing or following what people say.
