Sigh, the timing of this World Cup match is really unfriendly. Last night, I bought a wealth-management product that bets on Iran not to win. I crawled out of bed around 3 or 4 a.m. to watch the game. I was hanging on to my heart, feeling gloomy, and kept watching for an hour, and then—because my head wasn’t clear—I accidentally clicked a phishing link. In the end, the prediction market was correct, but all my past returns plus the principal were transferred away by hackers. I sincerely hope everyone will stay up as little as possible to play prediction markets—at the very least, avoid any actions. (Firsthand experience: your brain really won’t be able to handle it—you just fall into a trap without even realizing it.)
