Misc

I am interested in zero-sum environments, including both markets and games. In my spare time, I engage in trading activities in markets such as cryptocurrencies, U.S. stocks, and prediction markets, as well as games like Texas Hold'em and Mahjong.

I enjoy analyzing these competitive settings and trying to gain an edge through strategy and reasoning. It's just for fun — don't gamble. Recently, I have also been exploring how to use LLMs in these trading markets, including factor mining and automated trading systems, etc., to assist trading decisions.

I also enjoy video games, including single-player games on platforms such as PlayStation, Nintendo Switch, and Steam, as well as cooperative multiplayer games. My favorite game is The Legend of Zelda: Breath of the Wild—the 100+ hours I spent playing it are among the happiest moments of my life. For multiplayer games, I particularly enjoy League of Legends, which is probably the game I've spent the most time playing.
