A Polymarket trader has achieved a remarkable profit of approximately $280,061 over three days by trading 15-minute coin markets, focusing on Bitcoin (BTC) and XRP. The trader's profit and loss chart showed a dramatic increase, driven by strategic bets on short-term price movements. Key trades included a $36,799 bet on XRP, resulting in a $40,218 profit, and two BTC trades with profits of $26,494 and $25,461, respectively. These trades were executed with entry prices of 48 cents, 45 cents, and 60 cents, showcasing the trader's ability to capitalize on market volatility. The consistent success across multiple trading windows raises questions about how long such opportunities will remain available on Polymarket.
