#预测世界杯巴西VS海地 Today I saw in the group that someone bought a match between the United States and Australia. He predicted the US to win, but it showed he lost $900. What was the reason? Because he bet on the US to win in the second half. The score at halftime was 2-0, and the second half was 0-0, so he ultimately lost. He told us a principle: if you predict a World Cup match next time, like Brazil vs. Haiti, you need to see what type it is. Is it first-half win, second-half win, full match win, or first-half win? If you choose "no" for first-half, as long as it's a draw, you win. If the other team scores, you also win. The same applies to the second half. But if you bet on full match win, it means the entire game, and a draw doesn't matter which side wins; you lose. However, you can bet on a draw if it's not a draw. In that case, if it's a win or loss for either side, and you don't know which side to pick, you just bet on it. For example, Messi vs. Mbappé, the game is unlikely to be a draw, but you can bet on both sides having goals. This generally won't lose. Watching the game is similar to another kind of investment, which also depends on the risk-reward ratio. For example, now Brazil's probability is 89%, and when you buy, it needs to be at least 90% to make a purchase. The risk-reward ratio is very poor. At this point, you should buy Haiti at 3.7 and hold on longer; the higher the win rate, the better. If you wait four or five times, you can sell and make about one-third profit. This increases the chance of winning.
