Hey Product Hunt! 👋 I built PolyCopSim because I almost lost $35K copying a "profitable" Polymarket wallet. The wallet had $192K in profit. 55% win rate. Looked perfect on the leaderboard. But when I dug deeper, it was an arbitrage bot — its edge vanishes in milliseconds. If I had copied every trade, I would have been down $35K. That's when I realized: profitable wallets ≠ copyable wallets. Three things kill your returns when copy trading: → Execution delay (even 5 seconds can destroy 90%+ of alpha) → Slippage (your order moves the price against you) → Strategy type (arb bots and market makers are structurally uncopyable) PolyCopSim lets you paste any Polymarket wallet address and simulate what would have happened if you copied it — with realistic delays, slippage modeling, and automatic detection of arb bots. It grades every wallet from A+ to F, so you know in 30 seconds if it's worth copying or a trap. Free tier: 3 backtests/day. Pro: Unlimited runs, $39/mo. Would love your feedback — especially if you trade on Polymarket. Drop a wallet address and I'll run a backtest for you! 🧪
