This tool is for informational purposes only. Copy trading on prediction markets carries significant risks including but not limited to:
- Execution latency — you may get worse prices than the copied trader
- Slippage — especially in low-liquidity markets
- Past performance ≠ future results — a trader's history doesn't guarantee future success
- Market risk — prediction markets can be highly volatile
Always do your own research (DYOR) and never invest more than you can afford to lose.
