This year, on the prediction platform Polymarket, a trader turned $1,000 into over $2 million. A return of more than 2000 times sounds like a fairy tale, but the way this guy makes money is much more realistic than you think.

Careful analysis reveals that his secret to profits isn't about accurately predicting the outcome of matches, but rather monitoring platform quote delays through a program, capturing microsecond-level price differences for high-frequency arbitrage. In simple terms, it's about "tech-based money-making"—that's the real logic behind earning.

This reflects a harsh reality: top traders make money from cognitive advantages and execution ability, not from directional judgment or high leverage. Comparing this to the recent surge in Ethereum contract trading volume—a bunch of retail traders jumping in with 5x, 10x leverage—only to find the price didn't rise as expected, but instead became highly volatile and got liquidated—it's a stark contrast. One is fueled by market frenzy, the other quietly digging for profits in price gaps.

For ordinary traders, the lesson from this case is clear: don't always fixate on candlestick ups and downs to gamble on contracts. Instead, cultivate a mindset of "sniping" opportunities—pay attention to rule loopholes, price difference opportunities, and other details easily overlooked. Even if you lack high-frequency trading technology, understanding this principle is crucial: stable profits come from information gaps and precise execution, not from blindly increasing leverage after betting on the right direction. In the long run, the former is the true path to wealth.
