People who think quantitative trading is amazing and mysterious usually have low levels of education and cultural awareness. To be clear: the best quantitative firms are extremely low-key—that’s a rule for survival. Have you ever seen representatives from Hypersphere or Nine坤 appearing publicly? Earnings in the hundreds of millions or billions come with strict compliance and confidentiality requirements. Last year, Perp DEX farming yielded returns far exceeding 1,000% APR—Lighter isn’t the only one with returns like that. In every field, the most profitable players tend to stay quiet, because revealing strategies has negative expected value (EV). On-chain PVP requires visibility; copy-trading liquidity generates positive EV. Therefore, anyone claiming to be a top-tier quant can almost certainly be dismissed as a “dog.” Not 100%, but at least 99%. What about Li Xinye, the quant legend who once printed millions daily, ran his strategy for three years, and lived in Central Park, New York—do you think he ever talks about quantitative trading? Instead, you’re constantly chatting about dating guides for married women. P.S.: Li Xinye graduated from Tsinghua University’s Yao Class in Computer Science; Jin’s teacher studied at Jilin University, not in Computer Science.
