#预测世界杯巴西VS海地 Don't buy when Brazil has a 90% probability, because the risk-reward ratio isn't worthwhile. You instinctively earn 0.1 with a 0.9 chance, but the winning probability hasn't reached over 90%.

If you buy Haiti with a 5% chance, and sell when it reaches 7% or 8%, its ability and probability to make money are higher.
Because as soon as Haiti scores one or two goals, its victory probability is no longer below 10%.
In terms of risk-reward ratio, it's very good.
If you bet on football long-term, you'll find that events with high probability will only give you two chances to profit before you can't recover,
while low-probability events can be read many times.
Last time I bet on Brazil, it was clearly a high-probability win, but they lost and even drew, I forgot.
Anyway, I was so angry.
I read many high-probability scenarios, but in the end, I still lost money.
It's better to bet on 50% or 40% chances, like betting on the first half with no goals scored by either side—it's a different feeling.
