Nobody wants to lose their money easily and gamblers are not exempted from this fact, that's why people will want to bet on specific sports they have good knowledge of so they can have a good chance of winning in their different trials. I'll be very confident in placing an accumulator bet on a sport am knowledgeable of for it's that confident that creates the believe that I can have a chance to win compared to when I would be betting on sports I am a novice to.
Very well said my friend, betting on sports one completely have no knowledge of is like like someone who have never traded all his or her life before, and on the first day he or she wants to learn to trade, he or she goes into futures trading and uses a whole $100 or even more to long or short a coin, and without even knowing what long and short mean, that money is gone for good 😂..
I sometimes out it curiosity and wanting to try something new, bet on games I have completely no knowledge about, and so far, I can attest to the fact that ive lost most of such games, far more than the ones I've been lucky to win, so preferring to bet on certain kinda of games could also mean preferring not to throw your money away unnecessarily.
