BlockBeats News, December 30th, according to crypto KOL @gemchangeltd, an address signed as "JaneStreetIndia" on Polymarket's high-frequency trading crypto asset "15-Minute Guess Up or Down" has accumulated nearly $360,000 in profit. @gemchangeltd believes that this address is a bot developed by the well-known quantitative trading firm Jane Street. According to their analysis, this account often predicts both ways simultaneously and only places bets when the total cost is below $1. For example, an upward prediction at 48 cents, a downward line at 46 cents, totaling 94 cents. After market settlement, the odds for one of the lines are 1 dollar. Subsequently, if volatility opportunities arise, it will choose a single direction. This account has now been renamed to "Account88888".
