Recently, a certain exchange's trading competition mechanism changed, and it looks quite interesting. Originally, there were a total of 8,460 prize spots, now divided into two periods, with only 4,230 each. On the surface, it seems participants have more opportunities since one person can join twice and receive two rewards. But in reality? The spots have been cut in half, and the rewards per period are only around 23U.

From the platform's perspective, this is indeed a good move—extending user activity from one period to two, increasing user stickiness. But for participants, the competition has become more intense. The number of registrants won't decrease; in fact, it might even increase, which means the chances of winning haven't improved much, and it might be even more crowded. In the end, many people become mere spectators, with trading fees treated as costs.

Whether it's worth participating or not, everyone should weigh it themselves. Anyway, the return on investment should be carefully calculated before taking action.
