Keep in mind that there are not 100% correct and also any prediction site asking you to pay a certain amount of money to be added to a premium subscription for the prediction they make is most likely going to scam you - premium or not, they won’t always give you a game that’s 100% sure so if you believe them and then proceed to stake large amount on them you’ll only end up losing your money.

Make sure you always bet on sports you have knowledge of - don’t go around a bookie looking for sports like juicy odds to stake on and also don’t bet if you didn’t do proper analysis unless you just want to have fun and see if your guessing will come out well [as I do sometimes] - but if your goal is to minimize your loses then don’t try it make sure you know the teams you’re betting on, their weaknesses and strength, previous matches they have played in and their performances, the changes that were made and what impact it will have in their next performance make sure you out that in mind before you make any bet - don’t just go with “they have always come out victorious whenever they play against this team so they’ll surely win this round” don’t bet like that, check if theirs anything new.
