I've been trading on Polymarket for a while, and every time I wanted to backtest a strategy or analyze past BTC up/down market behavior — I hit a wall. There was simply no clean, structured historical dataset available. So I built one myself. I've been recording Polymarket's BTC prediction market data at 5-minute intervals — capturing the real-time odds (up/down prices) that traders were actually betting on. Over time, this became a surprisingly valuable dataset for anyone doing quantitative research, building prediction models, or just trying to understand how the crowd sentiment evolved around major price moves. What started as a personal tool turned into something I realized others needed too. If you're a quant, a researcher, or just someone curious about prediction market dynamics — I'd love to hear how you'd use this data. Happy to answer any questions! 🚀
