#Polymarket预测市场 Wait a minute, I just saw a crazy case that I need to sort out 😅

There is a trader on Polymarket who bet $32,500 that Venezuelan President Maduro would step down, and less than 24 hours later, he made over $400,000??? The return rate exceeded 1200%! Is this some kind of divine operation, or did he have insider information in advance?

According to the news, the price increase of this bet happened several hours before the official announcement from Trump, so now U.S. Congress members are pushing a bill to ban such "insider trading" activities. I start to understand—prediction markets are originally platforms for ordinary people to participate in, but if someone gains access to important information early because of their job and then trades on it, that’s unfair.

As a complete novice like me, I feel both excited and a bit scared. On one hand, seeing such high returns is tempting; on the other hand, I realize that the water in prediction markets might be very deep. I think I need to learn more about the platform’s trading rules and risk control mechanisms, or I might just get caught off guard and get cut.

Can any experts explain to beginners how to participate correctly in prediction markets?
