I kept missing copy trades by 10 seconds. Always a worse price. Always too late. PolyBot is what I built to fix it — a self-hosted Docker bot that mirrors top Polymarket wallets in real time, or trades 15-minute BTC windows using an AI ensemble (LightGBM + ExtraTrees). Your private key never leaves your server. No subscription. Kill switch + daily loss limits built in. Start free in paper mode. Go live when you're ready.
