Multiple bets have their advantages and disadvantages, but if you are a person who knows sports well and has a good streak, it is best to evaluate that multiple bets is what you need to do to improve your performance and perhaps win more, unlike Personally I am not very good at multiple bets, I always usually bet 1 time and 1 bet and based on my knowledge I do it that way, in my country there is a typical saying that says: "He who covers a lot, squeezes little" and I believe that making a strong bet on a sport, with some knowledge of what is being done, is worth a lot, however I think that I admire those who make multiple bets because their capacity raises them to the maximum.
Betting multiple times simply decreases your chances of winning anything, but increases your bet multiply. It's just math as always.
Instead of getting 50% chance to win x2, you have 25% chance to win x4. If you like the odds it's up to you. Most people either play with low bets, low probability, high payout, or choose to bet high with lower multiply but higher chances to win. Or you can go high bet low chance with high multiply if you like to go YOLO.
