Question 5

Is it safe to copy trade on Polymarket?

Accepted Answer

Copy trading on Polymarket through Polycopy includes several risk controls: you set your own position size limits, you can enable auto-close to automatically exit positions under certain conditions, and you maintain full custody of your funds at all times. However, all trading involves risk — you can lose money even when copying profitable traders. Past performance does not guarantee future results. Always trade with amounts you can afford to lose.
