I do refer few sites for reference and then take a call but I wouldn't recommend relying on it if you are placing bets with high amounts.
It's better to do a thorough research in such cases and then place a bet.
Using predictions sites as reference at time can be misleading because the sport bookers can collaborate with the predictions sites to mislead people into relying on their false predictions and when you use them you are going to lose your bets. To gamble on sport games is not that hard to do, just follow up the sports and you will know how to gamble and who is likely going to win. You should not be gambling on a sport you do not watch as you will have no idea on how to gamble then you go to rely on predictions site or use them for reference and they will mislead you into picking the wrong team to win. Although sport betting does not rely on luck but at times you can just depend on your luck as it can give you a better probability than prediction sites. So instead of depending on predictions sites for correct scores, you should depend on your luck.
You are right mate, using the prediction site as reference can be misleading because they themselves are not also very sure how the match is going to end. People that owns to prediction site are also just experienced gamblers or sport experts that uses different strategy to come up with their prediction but it doesn't mean that their prediction can bring 100% accurateaccurate results. Like you said, sport betting is not working difficult, just follow up sports activities and fixtures and the gambler can be able to at least know the team that can win or lose a match.
Now, the odds could actually tell which team or player could win the game but it also doesn't mean it is a sure shot. Even the x1.05 - x1.20 favorites could lose the game and I had my share of winning large amounts by betting against them.
The better way would be to do it ourselves when it comes to predicting games. That way even if we lose we won't blame anything or anyone but just us. However, the feeling that we will have when we win that game because of our analysis will be entirely different from just copying a prediction site. I can tell because I've done it so long and it's still the feeling of success when I won my own bets.
